2023. This prediction is largely due to the waning immunity following reduced exposure during the pandemic and the emergence of new viral variants. Think of it like this
after a period of relative quiet, the flu virus is likely to make a more noticeable comeback.
Predicted Prevalence of Different Influenza Strains
Experts predict a notable increase in the circulation of Influenza A(H3N2) viruses. This strain is often associated with more severe illness and hospitalizations, particularly among the elderly and those with underlying health conditions. Influenza A(H1N1) pdm09 is also expected to circulate, though possibly at lower levels than H3N2. The proportion of influenza B viruses remains uncertain, but we anticipate a presence, potentially contributing to the overall burden of disease.
Remember the 2017-2018 season? The dominance of H3N2 then led to a particularly challenging flu season. We need to be prepared for a similar scenario.
Factors Influencing Flu Season Predictions
Several factors play a crucial role in shaping the predictions. Firstly, the level of population immunity is a major determinant. Reduced exposure during the pandemic has lowered immunity in many individuals, making them more susceptible to infection. Secondly, the emergence and spread of new viral variants, with potential for increased transmissibility or virulence, significantly influences the severity and strain distribution.
Thirdly, environmental factors, such as temperature and humidity, can affect viral survival and transmission rates. Finally, vaccination coverage plays a critical role. High vaccination rates can help mitigate the impact of the flu season, reducing the number of severe cases and hospitalizations. Think of it as a multifaceted puzzle, where each piece – immunity, viral evolution, environment, and vaccination – contributes to the overall picture.
A concerted effort in all these areas is key to a smoother flu season.
