Rise in Flu Cases: Timing and Reasons Explored by Medical Experts for Flu Vaccination
The Southern Hemisphere has recently experienced a severe flu season, which may signal a similar situation for the United States. According to Dr. Strange, the influenza virus has been spreading around the country for approximately a month, with Texas and New York both reporting high flu activity.
Dr. Chang has also noted a significant increase in outpatient numbers of positive flu tests in the last two weeks, earlier than usual to see a spike in flu cases. This season, the flu shot includes protection for an influenza A H3N2 strain, H1N1 strain, and two types of influenza B.
As the cold weather sets in, we can expect to see increases in flu cases and other respiratory viruses. To minimize the risk of severe illness and severe outcomes, it is recommended to get vaccinated, practice hand washing, wear masks in crowded areas, isolate if sick, and control underlying health conditions.
Unfortunately, a recent survey found that nearly half of Americans do not plan to get vaccinated against the flu this year. This could potentially increase the severity of the flu season, as fewer people are protected against influenza. The absence of prevention measures from the pandemic, coupled with a drop in routine health interactions and vaccinations, could set up for a potentially bad flu season.
Texas, Georgia, and Washington D.C. are already seeing unusually high flu activity for this time of year. If sick or having flu symptoms, it is crucial to stay home to minimize the risk of infecting others. The Southern Hemisphere's flu season was more active than the prior two seasons, and this year's flu shot appears to be matching well to the circulating influenza virus in the US, but vaccine uptake is lower than desired, especially in older populations.
A decrease in immunity to seasonal flu due to historically quiet flu seasons could lead to a higher rate of severe illness this year. To prepare for a potentially intense flu season, it is essential to stay informed, take precautions, and prioritize health. The flu vaccine remains the best way to minimize the risk of severe illness and severe outcomes.
