As winter approaches, cases of respiratory illnesses, particularly influenza, Respiratory Syncytial Virus (RSV), and COVID-19 are expected to surge. To better understand why these infections spike during colder months and how Philadelphians can help protect themselves, we spoke with Dr. Karanvir Singh, Medical Director of AFC Urgent Care, about the factors driving the anticipated seasonal rise in respiratory illnesses, the role of vaccinations, and practical ways to stay healthy throughout the season.
Q: Can you explain why respiratory illnesses like the flu, RSV, and COVID-19 tend to spike during the fall and winter?
A: Respiratory illnesses like the flu, RSV, and COVID-19 tend to spike during the fall and winter months for several reasons. People spend more time indoors in close proximity to others, which facilitates the spread of viruses. Cold, dry air can weaken the body’s natural defense mechanisms in the respiratory tract, and viruses may survive longer in colder temperatures with lower humidity. Also, reduced sunlight exposure during the winter months can lead to lower vitamin D levels, potentially weakening the immune system.
Q: What are the most effective ways people can protect themselves and their families against respiratory illnesses this flu season?
A: To safeguard yourself and your family this flu season, it is essential to take proactive measures. Getting vaccinated is crucial; annual flu shots and up-to-date COVID-19 vaccines significantly reduce the risk of severe illness and hospitalization. It is also important to practice good hygiene by washing your hands frequently and thoroughly with soap and water. Maintaining a healthy lifestyle through adequate sleep, regular exercise, and a balanced diet supports your immune system. Lastly, staying home when you’re sick is vital to avoid the spread of illness to others.
Q: How important are vaccines in preventing flu and other respiratory infections, and can you combine vaccines for COVID-19 and flu?
A: Vaccines play a crucial role in preventing severe respiratory infections. The CDC recommends everyone ages 6 months and older receive an updated 2024-2025 COVID-19 vaccine and updated 2024-2025 flu vaccine to protect against the potentially serious outcomes of COVID-19 and to reduce the risk of influenza. Importantly, individuals can get a COVID-19 vaccine and flu vaccine during the same visit, making it convenient to ensure protection against both viruses without compromising effectiveness or safety. Please always check with your healthcare provider about your vaccine options and which is right for you.
Q: What are the different options for COVID-19 vaccines and where can Philadelphia residents get them?
A: In Philadelphia, residents have a few options for COVID-19 vaccines, including mRNA vaccines made by Pfizer-BioNTech and Moderna, and a protein-based non-mRNA vaccine made by Novavax. Remember, your next COVID-19 vaccine does not have to be the same type as the last one you received. So, if you’ve already had an mRNA vaccine, you can get boosted with a protein-based vaccine, and vice versa. Vaccines are available at pharmacies, clinics and doctor’s offices. To find a vaccination site near you, residents can visit the Philadelphia Department of Public Health website or search by ZIP code at Vaccines.gov. Please speak to your healthcare provider and do your research to determine which vaccine is right for you.
