Latest coronavirus news as of 1pm 31 March

In the UK, the risk of being reacquainted with the disease is 10 times higher with omicron.

Between July 2020 and March 2022, the ONS estimates the number of re infections in the UK.

When omicron was the dominant variant, the risk of reinfection was 10 times greater than when delta dominated.

There are different definitions of reinfection. The positive test result is defined by the ONS as a result of a number of negative test results. The number of negative results depends on when the reinfection occurred.

People are more vulnerable to reinfection when covid-19 immunity fades. Omicron has evolved to be more resistant to immunity.

Sarah Crofts from the ONS said in a statement that the risk of reinfection from omicron is higher than any other previous variant.

There are other coronaviruses news.

Over time, the WHO expects covid-19 to become less severe. A report by the World Health Organization shows how countries should respond to a worst-case, best-case and intermediate-case scenario. Booster vaccines will be unnecessary in the best-case scenario. In the worst-case scenario, a more harmful variant will evolve.

The most likely scenario is that the COVID-19 virus continues to evolve, but the severity of disease it causes reduces over time as immunity increases due to vaccination and infection.

The emergence of the less severe omicron variant made many people optimistic that the disease was evolving to be less dangerous. This does not happen often in evolution.

The risk of being hospitalized with omicron is reduced by up to 68 per cent if youvaccinate 5- to 11-year-olds. In the US, Pfizer/BioNTech vaccines have been available for this age group since October 2021, despite young children being at very low risk of severe covid-19. Two Pfizer/BioNTech doses have been found to cut the risk of being hospitalized in a nationwide study of 1185 children. The vaccine risks of immunising children are unclear, but the UK recently started offering it.

The self-isolation rate dropped after the legal requirement changed.

According to the ONS survey, less than two-thirds of people who test positive for covid-19 choose to beolate.

When the legal requirement to self-isolate in England was dropped on February 24th, the number of people who tested positive for covid-19 increased. They were interviewed between February and March when self-isolation was not required.

Less than two-thirds said they were self-isolated, compared with 80 per cent in a similar survey last month.

The legal requirement to self-isolate after a positive test for coronaviruses has been removed in England, according to the ONS.

When self-isolation was a legal requirement, compliance with self-isolation rules was much higher.

Past records in Wales and Scotland have already been surpassed.

The UK has a record number of suspected covid-19 cases.

According to the Office for National Statistics, 4.26 million people in the UK had the disease last week, just shy of the record 4.3 million infections in the first week of the year.

The number of covid-19 cases in England is approaching a new record, with an estimated 3,485,700 people having the disease in the week ending 19 March.

In Wales and Scotland, an estimated 192,900 and 473,800 people had covid-19 last week. In the week ending 19 March, an estimated 108,700 people in Northern Ireland had covid-19, equating to one in 17 people.

The number of true cases is much higher than what is reported. Over half a million people have tested positive for covid-19 in the last seven days across the UK. Deaths within 28 days of a positive test are relatively low, with 950 recorded deaths in the past seven days.

The rise of the Omicron BA.2 variant has led to an increase in the number of infections in England, Wales and Scotland.

In this rising variant, Northern Ireland was a few weeks ahead of the rest of the UK. Scotland has reached the highest level of any UK country in our survey.

In England, infections have increased in all regions and age groups, notably the over 50s who are at their highest levels since the survey began.

There are other coronaviruses news.

According to the data, less than half of the immunocompromised people in England have received a booster jab.

Three months after receiving a third full-dose jab, the Joint Committee on Vaccination and Immunisation recommends a reduced-dose booster for people with a weakened immune system. The number of people in England who had received a booster was just over half a million.

A Freedom of Information request by Blood Cancer UK shows that white British people with a suppressed immune system were the most likely to have received a booster jab. This is compared with 2 per cent of their counterparts from a Bangladeshi background and 4 per cent from a Black Caribbean background.

The omicron surge will be curbed by a two-stage, nine-day lock down. 70 per cent of China's total incidences were reported by the city yesterday.

The western and eastern parts of the city will be locked down from today until April 5.

The European Union approved a preventative therapy produced by AstraZeneca a week after it was approved in the UK. The combination of two long-acting antibodies that attach to the SARS-CoV-2 virus prevent it from entering human cells.

Adults and children over 12 who have a suppressed immune system are recommended to use Evusheld. People in an adult clinical trial who received Evusheld were 77 per cent less likely to develop covid-19 if exposed to the SARS-CoV-2 virus.

There were more than 60 cases recorded in one day.

China is continuing with its zero-covid strategy despite recording a record number of cases today.

Different provinces have introduced different restrictions due to the surge of the omicron variant. The nurse who died of an asthma attack when the hospital was closed for covid-19 was from Shanghai.

A record 1609 cases were reported today in the city of 25 million people, an increase of more than 60 per cent in just 24 hours.

Health officials are sticking to their strategy despite the surge.

By doing dynamic zero-COVID, we can eliminate the hidden dangers of the epidemic, avoid the run on medical resources that may be caused by large-scale infections and prevent a large number of possible deaths of the elderly or those with underlying diseases.

There are other coronaviruses news.

The study found that the vaccine gap between ethnic minority groups and white groups in the UK was due to the former having lower levels of trust in the medical establishment and poor past healthcare experiences. The proportion of white people in the UK who were not living in a care home had been vaccine free as of 13 January 2021. The researchers write that low trust and poor past experience may explain a quarter of the vaccine gap.

According to the University of Florence, long covid symptoms may differ depending on the variant that caused the initial infections. The team looked at more than 400 people who were hospitalized with covid-19. 76 per cent of the participants reported at least one symptom at 4 to 12 weeks after discharge.

When the original SARS-CoV-2 strain was circulating, it was more likely for people to experience a loss of smell, hearing and swallowing. When the alpha variant was dominant, more of the participants experienced muscle aches, insomnia, brain fog and depression or anxiety.

The BA.2 sublineage, which has caused a surge in cases and hospitalisations across Europe, could pose a risk to the US, where vaccination rates are lower. In the US, 66.19 per cent of people are fully vaccination, compared with 73.83 per cent in the UK. Anthony Fauci, the US Chief Medical Adviser, said that he was not expecting a surge.

In February, Covid-19 caused 5.6 per cent of deaths.

Covid-19 was the third leading cause of death in England and the sixth leading cause in Wales last month.

Covid-19 was the main cause of deaths in England in February, according to the Office for National Statistics. The leading cause of deaths last month was dementia, with an incidence of 11.6 per cent. Ischaemic heart disease, brought on by narrowing of the arteries, was the leading cause of death in Wales.

According to government data, the number of recorded cases of the respiratory syncytial virus increased in the past week. The more-transmissible omicron BA.2 sublineage is probably the reason for this. Deaths within 28 days of a positive test increased by 17.9%, but covid-19 may not have caused all of them.

A survey by the ONS suggests that almost all of the people in the UK have an immunity to the disease. It's not clear what threshold is required to protect an individual from different covid-19 variant.

The vast majority of the UK population now have antibodies against COVID-19, which will hopefully protect most from developing severe symptoms.

There are other coronaviruses news.

A person who is immunocompromised has been found with a variant of the disease that is resistant to the drug. After six months, the person needed supplemental oxygen because they had covid-19 for six months. Their viral load went up while they were being treated. A team from the Yale School of Public Health found that anidase that is involved in the replication of the coronaviruses had changed, making it resistant to remdesivir. The person's immune system couldn't fight off the virus for so long that it is thought to have caused this.

Albert Ko said that the threat of antiviral resistance is a critical concern.

Moderna plans to apply for regulatory approval in the US for its vaccine for children under 6 years old. Two doses of the jab were found to be effective at preventing infections in young children and in children less than two years old. The covid-19 vaccine is the first to be approved for under 5 year olds in the US.

The global Covax scheme donated 2.2 million jabs to be used in Africa, but almost 840,000 of them expired before they could be used.

Almost half of UK adults don't see friends and family as much as they used to.

A survey suggests that life may not be normal on the two-year anniversary of the UK's first lockdown.

A survey done by Bobby Duffy and his colleagues at King's College London found that just under a third of adults said they feel more alone now than they did before the epidemic. Almost half said they see their loved ones or leave the house less.

A third of people say their mental and physical health has deteriorated, with 36 percent saying they have gained weight and 32 percent saying they have lost sleep.

These findings, marking the two-year anniversary of the first national lockdown, are further evidence of how life in the UK has changed for many people, affecting a range of aspects of our physical and mental health.

Positive changes may have been spurred by the Pandemic. More than a third of the adults interviewed said they are exercising more, while more than a quarter said their mental health has improved.

There are other coronaviruses news.

Danny Altmann told The Guardian that long covid could cause a generation to be affected by disabilities. According to the Office for National Statistics, 1.5 million people in the UK were experiencing symptoms more than four weeks after catching covid-19. The lifting of restrictions suggests that the impact is not being taken seriously.

More than 10 million covid-19 cases have been reported in South Korea. The daily recorded cases of the more transmissible omicron variant increased from 5100 on 20 January to 404,665 on 18 March. The number of covid deaths has doubled in about six weeks, which has led to increased demand for funeral homes. South Korea's case numbers and death toll are relatively low compared with other countries, which is probably due to the fact that 87 percent of its population is double-vaccinated.

A small study shows that covid-19 can't be transmitted via an organ donation. Four recipients who received organs from four donors who had tested positive for the disease were looked at by Emily and her colleagues at Duke University School of Medicine. According to the results presented at the European Congress of Clinical Microbiology and Infections in Lisbon, none of the recipients contracted covid-19. In February 2021, a different team reported that a lung donor had transmitted the disease to a recipient.

Covid-19 is linked to an increased risk of type 2 diabetes.

People who have had covid-19 within the past year may be more at risk of developing type 2 diabetes for the first time or being prescribed medication to manage their blood sugar levels.

The VA Saint Louis Health Care System in the US used data from the US Department of Veterans Affairs to review the medical records of 181,280 people who tested positive for covid-19 between March 2020 and September 2021. The team compared the number of new diabetes cases among these veterans with the number of people who had no evidence of a covid-19 infection. None of the participants had diabetes at the beginning of the study.

People with a mild or no covid-19 infections were more likely to develop type 2 diabetes.

The body can't make enoughinsulin or the hormone that is produced doesn't work properly, which leads to type 2 diabetes. The Washington Post reported that Al-Aly said that the virus may inflame cells and decrease their efficiency.

Al-Aly said that the link between covid-19 and type 2 diabetes was observed among all the groups.

In August 2020, a different team uncovered a link between covid-19 and type 1 diabetes in children, with four trusts in London seeing around double the usual number of new cases during the early months of the pandemic. When the body mistakenly attacks cells in the pancreas, it causes type 1 diabetes.

A team in Germany recently linked covid-19 to a higher risk of type 2 diabetes among adults.

People who have tested positive for covid-19 are more likely to have a baby with a birth defect. The medical records of 43,886 pregnant individuals were analysed. Premature birth, clot and sepsis were three times more common among people with a known covid-19 infection.

The most important thing people can do to protect themselves and their baby is to get vaccinations, according to the co-author.

The number of people with covid-19 in Scottish hospitals has reached a record high, with 2128 cases on 20 March. Scotland recently lifted many of its covid-19 restrictions. Not everyone in the hospital is admitted for covid-19.

The vaccine is thought to have helped a person who was immunocompromised.

Two doses of the Pfizer/BioNTech vaccine are thought to have cleared a person who had tested positive for the virus more than seven months before. This is the first time a covid-19 vaccine has been used to treat an infectious disease.

Wiskott-Aldrich syndrome is a rare genetic disease that weakens the immune system. In December 2020, he tested positive for the disease. His immune system was unable to fight off the infection for 218 days.

Stephen Jolles at the School of Medicine at the University of Wales said that they decided on a unique therapeutic approach because of the positive tests.

We administered two doses of the BioNTech Pfizer vaccine one month apart, and very quickly saw a strong antibody response, much stronger than had been caused by the natural infection.

After the first vaccine dose, it was confirmed that he was free of the disease.

Mark Ponsford said that this is the first time that a vaccine has been used to clear persistent COVID-19 infections.

There are other coronaviruses news.

People aged 75 and over, care home residents and people who have a weakened immune system can now get a booster jab. One in 20 people in England had covid-19 in the week ending 12 March according to the Office for National Statistics. The booster programme is supposed to protect people from the omicron BA.2 sublineage. Some groups in Scotland and Wales are already getting boosters.

China reported two covid-19 related deaths in March. Both people died of underlying medical conditions, with mild covid-19 symptoms, according to the National Health Commission of China. More than two-thirds of the country's cases have been reported in the province of Jilin. China's reported new infections hit a rolling seven-day average of 2333 on 19 March.

There are more than 5000 new cases of Covid-19 a day in China.

The number of new cases in China yesterday was more than double the previous day's count and its highest daily tally since the start of the epidemic. The surge has led to the introduction of full or partial lock downs in many cities.

Until recently, China had largely kept outbreaks under control. The current surge is probably caused by the omicron variant, which is more transmissible than previous ones.

Cities across the country are locked down. Jilin is the worst affected province, accounting for more than 3000 of China's new reported cases. Jilin's governor promised to achieve community zero-covid in a week.

China's rising cases are related to a global increase in the disease. The number of infections reported by the World Health Organization increased by eight per cent between 7 and 13 March. The number of new weekly cases had been decreasing.

There are other coronaviruses news.

There are face covering rules in Scotland. Scotland reported 38,770 new covid cases on 15 March, up from a daily average of 6,900 three weeks ago. There will be no covering on public transport or in shops on 21 March. The BA.2 omicron sublineage is more transmissible than the initial omicron variant and accounts for 80% of Scotland's cases. There is a link between covid-19 and cardiovascular changes among unvaccinated people. A group of 38 people who had been exposed to the disease less than six months before were looked at by a group of researchers. Mild or moderate infections were linked to cardiovascular changes that resulted in a raised heart rate, which affected some of the participants' ability to climb stairs or walk.

The surge in cases is thought to be the result of waning immunity, as well as the more transmissible omicron sublineage.

The scrapping of England's React study at the end of March has been criticized. Each month, react randomly tests 150,000 people for the disease. One scientist told The Guardian that the move was about as far away from the science as you can get.

Older people should be offered a fourth vaccine dose. In England, people with a suppressed immune system, living in a care home or over the age of 75 will be offered an additional jab in April. The age requirement is being called for to be lowered. A small Israeli study of healthcare workers found that a fourth dose increased some levels of antibody, but it did not increase immunity.

There are other coronaviruses news.

China's covid-19 cases have doubled in 24 hours. There were more cases reported on 13 March than on the previous day. The biggest city in China, Shanghai, has been forced to shut down due to this. Omicron and a rise in infections are thought to be behind the surge in cases.

The sotrovimab has been linked to a drug-resistant variant of the disease.

A study in Australia suggests that sotrovimab, a treatment for covid, may cause the coronaviruses to acquire a resistance to the drug.

Sotrovimab is able to stop the virus from entering cells. Sotrovimab can be given to people within five days if given through a drip.

The first 100 people who received sotrovimab at a healthcare facility in New South Wales were reviewed by Rebecca Rockett and her colleagues. Eight of the people who were treated persistently tested positive for the disease, and had airway samples collected before and after they received sotrovimab.

The drug sotrovimab was effectively inactive in four of the patients because of the spike mutations that developed after it was administered.

The researchers don't want to see resistantviruses in the community because that will mean that a lot of other people can.

The World Health Organization has warned that the pandemic is far from over. The number of deaths in the week of February 28 to March 6 fell by 8 per cent compared to the previous week.

A programme that looks for the disease in wastewater has been rolled out in Northern Ireland. Wastewater samples from 31 sites are collected every day and sent to a Queen's University lab for testing.

After the peak of the omicron surge, covid deaths and new infections declined.

The number of covid deaths in the week of February 28 to March 6 decreased by 8 per cent. The WHO reported that the number of recorded new infections decreased by 5 per cent.

More than 10 million new covid cases and 52,000 deaths were reported across the WHO's six regions.

The Western Pacific Region saw a 46 per cent increase in case numbers. The Western Pacific and Eastern Mediterranean regions sawvid deaths rise by 29 and 2 per cent, respectively.

The omicron variant appears to have peaked in February. The WHO stressed that countries vary in their testing strategies and therefore any trends should be taken with a pinch of salt.

There are other coronaviruses news.

In the UK, reported coronaviruses cases have increased by two-fifths week-on-week. The number of people who reported a positive test between 2 and 8 March increased by 90,944 from the previous week. There were 8763 people admitted to the hospital between 26 February and 4 March, an increase of 11 per cent from the previous week. The number of deaths has slightly declined. Between 2 and 8 March, 729 people died within 28 days of a positive test, 12 less than the previous week.

According to the National Cancer Research Institute, the number of cancer research studies funded in the UK fell in the first year of the pandemic. The money given to these projects was slashed by 57 per cent. The closing of charity shops is thought to have contributed to the problem.

Booster jabs increase protection against omicron, but efficacy begins to fall after two months.

After two months, the vaccine protection against the omicron variant starts to decline.

The period in which the omicron variant started to spread widely in the UK was studied by researchers at the UK Health Security Agency. The data showed that over one million people had been affected by the variant.

The researchers only looked at whether people developed a mild illness or not.

They found that a booster dose increased protection against illness from the omicron variant. The Pfizer/BioNTech vaccine was only effective against the omicron variant for 25 or more weeks. The third booster dose increased the protection to 67.2 per cent. After 10 or more weeks, this dropped to 45.7 per cent.

After two to four weeks, the Moderna booster was 73.9% effective against mild illness from the omicron variant. After five to nine weeks, this dropped to 64.4%.

There are other coronaviruses news.

China had its highest daily number of coronaviruses infections in two years yesterday. China reported the highest number of domestic transmitted cases in a single day since March 2020.

The death toll from covid-19 has passed six million. As of Monday midday, the toll stood at 6,000,394.

This number is likely to underestimate how many people have died from the virus. Many parts of the world have poor reporting and testing mechanisms.

Immune-Suppressing treatment reduces deaths in people who are already taking covid-19 medicines.

The arthritis medicine baricitinib has been shown to help people with severe covid-19. In the later stages of covid-19, over activity of the immune system can cause damage to the lungs and the blood clotting system.

Adding baricitinib to the other treatments reduces the death rate by 13 per cent, according to a large UK trial. Dexamethasone is the first medicine shown to reduce deaths in covid-19 and it is already being given to most people in the study. It suggests that baricitinib could reduce deaths by one fifth.

Baricitinib works by blocking the actions of an immune system compound that is raised in severe covid-19. It is easier to give than tocilizumab because it is in tablet form. More than a third of people in the trial received tocilizumab, and they still had a reduction in deaths from baricitinib.

Baricitinib is an oral agent that has a short half-life and is less expensive than steroids in low/middle-income country settings.

There are fears that Hong Kong will be locked down as cases of covid-19 and deaths due to the virus are soaring. The city in the middle of an omicron surge has relatively low vaccination rates for its elderly. Two of Hong Kong's largest retail chains are rationing some food and medicine.

A study used a genetic technique called Mendelian randomisation to link people's genes with their risk of illness, and found that measuring fourteen proteins in the blood can help predict if people will get severe covid-19. The study found that there are at least six proteins that cause higher rates of hospitalisation or death. Previous studies have shown that people with blood group A are more likely to be admitted to hospital with covid-19.

Depression andemic anxiety are linked.

Women and young people are among the worst affected by depression and anxiety, according to a WHO briefing.

The rise in social isolation, as well as grieving loved ones, financial worries, and fear of infections, is partly to blame for the rise in mental health issues.

Most of the countries surveyed have included mental health support in their recovery plans, however, the WHO has stressed there are still gaps in care.

The information we have now about the impact of covid-19 on the world's mental health is just the beginning, according to the WHO.

There are other coronaviruses news.

The first oral antiviral drug for people with non-severe covid who are most at risk of hospitalisation, such as older age groups or people who are immunocompromised, is recommended by the WHO. There are six studies with a total of 4796 participants. The review found that if you give four molnupiravir tablets twice a day for five days, you can reduce the risk of hospitalisation by 30 per cent.

It is thought that covid restrictions resulted in 720,000 fewer infections of the disease in 2020. The team behind the work was surprised by their findings, having thought that the rates of mosquito-transmitted infections would increase when people were forced to spend more time at home. The latest results, published in The Lancet Infectious Diseases, contradict previous research by a different team, who warned that an additional 2008 dengue cases may have occurred a month in Thailand amid its 2020 restrictions.

Pre-existing inequalities between the sexes may be intensified by the Pandemic. Between March 2020 and September 2021, researchers from the US reviewed data on issues like healthcare access, economic concerns and safety for 192 countries. Girls were more likely to drop out of school than boys, and women were more likely to report an increase in gender-based violence than their male counterparts.

The coronaviruses have pushed back fertility treatments in many countries, with Scotland facing some of the biggest delays.

From October 2020 to September 2021, a team of researchers sent surveys to fertility clinics in Asia, Africa, Europe, North America and South America.

In 34 countries, people wait an average of 59 days for in-vivo fertilization or a sperm injection, when a single sperm is inserted into an egg in a laboratory. 60 days was the average for frozen embryo transfers. These occur when the embryo from the previous cycle is put into the womb.

The largest delay in fertility treatments was reported by a clinic in Scotland. Only Austria, China, Germany, Hong Kong, Norway and Portugal reported no delays.

The European Society for Human Reproduction and Embryology advised people to avoid procedures like in-vivo fertilization due to uncertainty about how the coronaviruses affect pregnancies. The American Society for Reproductive Medicine delayed any but the most important care cases.

The need to reduce the burden of non-essential medical treatments in hospitals to allow resources to be allocated to dealing with people with COVID-19 guided the need to stop or delay treatment.

There was a lack of advice regarding the provision of psychological support and how to prioritize patients.

Care home staff in England will no longer be required to have coronaviruses vaccines. Anyone working in a Care Quality Commission-registered care home was required to have two vaccine doses if they were medically exempt. The government has said that the public's immunity to the coronaviruses is high due to widespread vaccine use and people recovering from the omicron variant.

Some cases of long covid may have damage to the nerves. A small study of 17 people with long-term symptoms found that 59 percent had signs of nerve damage.

Preliminary laboratory studies suggest that modified T-cells could help treat covid. T-cells of people who had recovered from covid-19 were genetically modified to be resistant to the drug tacrolimus, which is often given to people who have had an organ transplant to prevent rejection. The modified cells attacked the coronaviruses in a laboratory experiment.

Children between five and 11 years old are less protected from two doses of the Pfizer/BioNTech covid-19 vaccine.

The Pfizer/BioNTech covid-19 vaccine protects against infections in children younger than 11 years old.

There were over one million fully vaccine-vaccinated children who lived in New York and researchers analysed covid-19 cases and hospitalisations. There was a surge of covid-19 infections from the omicron variant.

The Pfizer/BioNTech vaccine's protection against hospitalisation fell for older children by the end of January, according to the team. Protection against hospitalisation for children aged five to 11 fell from 100 per cent to 48 per cent.

In the 12 to 17 age group, the effectiveness dropped from 66 percent to 51 percent.

The difference between the two age groups is striking, according to the New York Times.

Some of the discrepancy in the vaccine's effectiveness could be explained by the fact that those in the younger age group receive a 10 microgram dose of the vaccine.

There may be a case of deer-to-human transmission in Canada. The team traced at least one case of covid-19 in humans to a strain of the virus found in white-tailed deer.

White-tailed deer have been found to have covid-19 in the US and Canada. 17 deers were found to have a previously unknown strain of covid-19 in a study.

One person who had been in contact with deer tested positive for the same strain.

Hong Kong reported the highest number of new infections and deaths since the beginning of the Pandemic. The city has seen a huge surge in covid-19 cases. Hong Kong's fatality rate is one of the highest in the world and may be due to lower vaccination rates in older age groups. The city will begin mass testing its 7.4 million residents in March.

There are previous updates from February to January, November to December, September to October, July to September, and June to July.
