2 charts show how Omicron symptoms differ from Delta and past coronavirus variants

People with Omicron are more likely to have sore throats.

Omicron patients report fewer cases of cough, cough, and loss of taste or smell.

The Omicron symptoms are shown in the charts below.

Doctors noticed slight differences in their patients' symptoms as soon as Omicron spread. Mild, coldlike symptoms were becoming more common. The hallmarks of COVID-19 had dwindled.

The most reported symptoms of Omicron are similar to a cold, especially in people who've been vaccine-vaccinated, according to a scientist.

Hundreds of thousands of people in the UK are being tracked by the study using a smartphone app. The advent of the Delta and Omicron variant has changed the symptoms of COVID-19.

The chart shows how Omicron symptoms compare to their predecessors.

The top five symptoms for people who had a positive COVID-19 test in the past few weeks were nausea, headaches, fatigue, sneezing, and sore throat. A majority of people in that group had a persistent cough and a high temperature. The chart shows that loss of taste or smell was less common.

70% of the UK population has had at least two vaccine doses as of Thursday, according to the data.

A sore throat, headaches, and congestion are some of the symptoms of omicron cases.

There has been an increase in COVID-19 cases recently at the outpatient clinic of Dr. Jorge Moreno. He said that most of the patients were vaccine-free, so their symptoms were relatively short-lived.

Many patients start out with a dry throat that makes them feel pain when they swallow.

"It's a very prominent symptom, and it's something that you should be aware of," said the assistant professor of medicine. It's not like a tickle in the throat. If they're reporting it, they're saying that their throat feels raw.

He said that a sore throat was often accompanied by headaches and a cough a day or so later. Ryan Noach, the CEO of Discovery Health, the largest private health insurer in South Africa, said at a December news briefing that Omicron patients commonly reported a scratchy throat first.

"Cough is still part of the symptoms," he said. He said, "It's not as bad as it was." He said that people who are vaccinated don't have respiratory symptoms as much.

Dr. Carlos Ramirez was in Oakland, California, on May 12, 2020, to examine Juan Perez.

Omicron patients have a relatively rare loss of smell.

Less than 20% of people in the UK who recorded a positive COVID-19 test were logging the symptom into the app. When the Delta variant was dominant in the UK, the loss of smell was the sixth most common symptom. In March, before Delta was detected and vaccines were widely available, 60% of UK adults ages 16 to 65 on theZoe app reported loss of smell at some point in their illness.

Outpatients who reported feeling tired and achy more often reported fatigue.

He said that he has seen more people report fatigue as one of their main symptoms. They're young people that push through things. They need a break. They need to sleep. They are napping more.

Why are symptoms different?

The scientists don't know why the symptoms are changing.

Vaccines help reduce the severity of disease, but Omicron might be a less virulent virus on its own. Two recent lab studies suggest that Omicron may not be as effective at attacking lung cells as before. Omicron was found to reduce the risk of death or hospitalization from COVID-19 by 25% compared with Delta.

The way the virus replicates in the body may be changed by Omicron. A December study from the University of Hong Kong found that Omicron replicates 70 times faster in the main airways than Delta, but 10 times slower in the lung tissue. A study released earlier this month showed that the Omicron viral load peaked in saliva one to two days before it peaked in nasal swabs, a sign that the Omicron may be spreading.

A person's vaccine status can lead to a series of symptoms.

The people that are unvaccinated go through a longer course. People who are vaccine-free have a middle-of-the-way course. It's almost like an old cold for the boosted people, with symptoms like the sore throat.

Patients used to feel sick for around 10 to 14 days before Omicron. He said that people who received a booster shot reported shorter bouts of illness than people who received fewer shots.

He said that those individuals who are boosted within five days will have their energy level return. Their symptoms have been solved.

Less than 20% of people in the UK have reported losing smell recently. The symptom was a hallmark of COVID-19.

The omicron variant is less severe than the delta.

Polish scientists have found a gene that doubles the risk of becoming severely ill with COVID-19, a discovery they hope could help doctors identify people who are most at risk from the disease. With vaccine hesitancy a major factor behind high coronavirus death rates in central and eastern Europe, researchers hope that identifying those at greatest risk will encourage them to get a shot and give them access to more intensive treatment options in case of an infection. "After more than a year and a half of work, we were able to identify a gene responsible for a predisposition to becoming seriously ill with coronaviruses," said Health Minister Adam Niedzielski.

The World Health Organization said Friday that it recommends two new drugs as treatments for COVID-19 and that the extent to which they can save lives will depend on how widely available and affordable they will be. The first drug that is recommended for patients with critical or severe disease is baricitinib. It is part of a class of drugs that suppress the over stimulation of the immune system.
