How to protect yourself from the Flu, RSV, and Covid-19 this winter

With colder weather driving people indoors there is increased exposure with decreased immune responsiveness. Subsequently, during this winter season, hospitals are experiencing high cases of RSV, flu, and even COVID-19. While all three viruses are present, some have referred to this as a “Tripledemic.” While the Flu, COVID-19, and RSV are all respiratory viruses, there are some differences in how they spread. Continue reading to learn more.


RSV is a common and highly contagious respiratory virus that is spread primarily though droplets and causes cold-like symptoms in young children. Due to all the COVID-19 precautions, many young children haven’t been exposed to the virus in the last few years, but now with restrictions lifted, many are being infected. While children under the age of two are most likely to contract RSV, it has been reported that more adults over the age of 65 have been contracting the virus. RSV is especially dangerous for younger children it can lead to breathing difficulties because their lungs aren’t fully developed. While there is currently no vaccine for RSV, babies born prematurely or with an underlying medical condition may qualify for RSV antibody injections to help prevent severe disease.


 Flu infections are significantly higher than in the past two winter seasons additionally due to the lifted COVID-19 precautions. With this season’s flu outbreak being the worst in a decade, the CDC reports that there has been at least 15 million flu illnesses so far. The flu can spread from respiratory droplets, aerosols and though contaminated surfaces. Vaccines to protect against influenza are tailored each season, based on the prior season’s flu strains, to minimize risks of infections, complications, hospitalizations, and flu-related deaths. 


COVID-19 spreads when an infected person breathes out droplets and then breathed in by other people or land on their eyes, nose, or mouth. People who are most likely to get very sick from COVID-19 are older adults, people who are unvaccinated, and people with certain medical conditions. The newest Covid-19 variant XBB.1.5. (a descendent of Omicron) is quickly spreading in the U.S. and has been described as the most transmissible form of the virus yet. Compared to the flu, COVID-19 may take longer to show symptoms and be contagious for longer periods of time. Anyone infected with COVID-19 can spread it, even if they do not show symptoms. It is a good idea to test for COVID-19, but even if the test is negative, keep in mind that it will not rule out RSV or other infections.

Experts warn that the simultaneous presence of RSV, flu and Covid-19 could become the normal during winters for years to come. Vaccines, testing, antiviral treatments, and everyday hygiene measures remain the best tools to slow transmission of the viruses and limit the severity of infections. Since RSV, flu and Covid-19 are all respiratory viruses, they are difficult to distinguish when symptoms start. All of those viruses carry similar symptoms.
