Flu cases are surging across the country, with over half of states now at “very high” levels of activity. But can some people get the flu twice in one season? According to infectious disease experts, it is possible.
The flu is caused by influenza viruses that can lead to mild to severe illness and even death. There are four types of flu (A, B, C, and D), but only Flu A and Flu B contribute to the annual “flu season” that typically starts in October and lasts until March or April.
This year’s flu season feels worse than normal, with dominant type Influenza A making up 80% of lab-confirmed cases. However, it is possible to contract a different strain, such as H1N1 or H3N2, even if you have immunity from the previous strain.
Dr. Amesh Adalja, an infectious disease expert at Johns Hopkins Center for Health Security, says that getting two strains in one season can happen. “You could get influenza A and then get influenza B, yes,” he said.
To prevent the spread of flu, experts recommend proper handwashing, avoiding touching your eyes, nose, and mouth, avoiding people who are sick, wearing masks when necessary, and staying home from work or school until fever-free for 24 hours.
If you’re experiencing symptoms that could be the flu, it’s essential to get tested. The Centers for Disease Control and Prevention (CDC) recommends starting antiviral drugs like oseltamivir (Tamiflu) within one to two days of symptom onset.
