The following essay is covered in The Conversation, an online publication.

Kids are out of school and social activities when there is a cold or flu. More children are going to emergency departments and hospitals this year than in the past.

The Orange County health department declared a state of emergency due to a record number of hospitalizations for respiratory infections in children. Emergency rooms in Maryland have run out of beds because of the high number of respiratory syncytial virus infections. Emergency departments are having to refer patients to other departments.


The winter respiratory virus season in the US started earlier this year than in the past. This early wave suggests that the situation could get worse for people of all ages, especially children, since peak infections usually occur in late December or January.

We are experts in epidemic analysis for respiratory infections. When the patterns are unusual, we watch them closely. Over the last few months, we have become more concerned about the number of hospitalizations for children.

The ‘triple threat’

The Centers for Disease Control and Prevention issued a health advisory about respiratory infections in children. The CDC and other health experts warn that there is a triple threat of respiratory illness from the flu, respiratory syncytial virus and carbon dioxide.

The increase in infections so early in the season is not yet clear. Health experts have some clues about what it means for the coming months.

The pattern of infections seen in 2020 and 2021 is expected to repeat in 2022. There were a number of factors that contributed to the previous winter surge, including the emergence and spread of new viral variant, more people gathering indoors, and people coming together for the holidays.


Most COVID-19 precautions, such as avoiding group activities or using masks in public, are more relaxed than before. It's difficult to say how big the next wave of COVID-19 will be.

The seasonal flu almost always hits in late October. The flu season arrived earlier than in the past. Our read of the data shows that the number of kids hospitalized for the flu is close to 10 times what it has been in the last decade.

The flu tends to peak in the winter months. There was an unexpected summer wave that was well before the start of the fall respiratory virus season.

In a typical year, the media doesn't pay much attention toRSV. Mild illness is usually caused by it. Most kids get the virus before they are 2 years old.

There are serious consequences for children under the age of 5 when it comes to respiratory infections such asRSV. It is the most common cause of lower respiratory infections in young children, and more severe illnesses can lead to pneumonia and other serious problems.


Why children are particularly at risk

Young children are more likely to get sick from flu and other diseases. Babies less than 6 months old stand to suffer the most, with nearly double the risk of death compared to other children less than 5 years of age. It is four to five times more likely for infants to be hospitalized than older children.

The immune systems of the youngest children are not fully developed and don't produce the robust immune response seen in most adults. Babies younger than 6 months are too young to be protected against flu and COVID-19.

The viruses present challenges on their own, but their co-circulation and surge in infections creates a perfect storm for multiple viruses to enter the same person at the same time. It is possible that Viruses act together to cause damage to the Respiratory Tract.

Co-infections are usually rare. Children are more likely to get co-infection than adults. It can be difficult to diagnose and treat co-infections, which can lead to more serious illnesses.

Factors behind the triple threat

There are a number of reasons why the US may be seeing a surge in respiratory infections in children. The COVID-19 protection strategies help prevent the spread of respiratory pathogens. Children are usually exposed to respiratory viruses in school and daycares.


Efforts to stop the spread of COVID-19 seem to have suppressed the circulation of other Viruses. The flu season in the U.S. was almost completely absent in the winter of 2020.

The decrease in viral activity means that children missed out on some of the benefits of being exposed to pathogens in the first few years of life. Immune debt can contribute to an excess of respiratory infections in children.

The emergence of new COVID-19 variant and the natural evolution of seasonal influenza viruses mean that we could be seeing a combination of strains that cause more severe illness.

Proactive steps people can take

The importance of prevention is highlighted by the surge in respiratory infections. Vaccination is the best way to prevent diseases. Everyone over 6 months of age can receive a vaccine that protects against COVID-19 and flu. They have been shown to be effective and safe.

The most recent data on the newly updated bivalent COVID-19 booster vaccine suggests that it produces a more rigorous immune response than the original COVID-19 vaccines.


If you want to protect infants younger than 6 months old against flu and COVID-19, you should get a vaccine while you're pregnant. Maternal antibodies cross the placenta to the baby, which reduces the risk of hospitalization in young infants. Vaccinations can help protect infants.

Other preventive measures, like hand- washing, covering sneezes and coughs, staying at home and isolating when sick, can help to protect the community. Paying attention to local public health advisers can help people keep themselves and others safe by giving them the most up to date information.
