Flu Season Update: What You Need to Know

As we navigate the current flu season, it's essential to stay informed about the latest developments and tools available to help you stay healthy. The United States is experiencing a second peak in flu cases, with doctor's office visits for flu jumping past the previous season's peak at the end of last month. The US Centers for Disease Control and Prevention (CDC) estimates that there have been at least 20 million cases and 11,000 deaths from flu this season.

New Tools to Help

Fortunately, there are new tools available to help you identify whether your illness is caused by Covid-19 or influenza. Over-the-counter tests that can detect both viruses are now available for purchase at most pharmacies or online. These tests use self-collected nasal swabs and provide results within 15-30 minutes. Several companies have received emergency use authorization from the US Food and Drug Administration, and one test, Healgen, has received authorization for marketing outside of emergency use.

What to Do If You Test Positive

If you test positive for flu or Covid, it's crucial to isolate yourself as much as possible to protect your loved ones and get in contact with your doctor, especially if you have underlying health conditions. Experts stress the importance of isolation to stop the spread of illness. Dr. Sarah Nosal, a primary care physician, notes that "it's really about helping both prevent other exposures and the basics of caring for you."

Getting Treatment Faster

The home tests may also help patients get treatment faster. Dr. William Schaffner, an infectious disease expert, says that his emergency department is currently full of people with respiratory infections, the majority of whom are sick with the flu. He notes that "if the testing were widely available... then that might motivate patients to contact their providers earlier."

Differentiation Between Flu and Covid

The differentiation between flu and Covid is critical when determining treatment and managing symptom expectations. Covid-19 can cause more serious illness in particular cases, and patients who test positive for Covid could also be at risk of long Covid. Both viruses have different antiviral treatment options, and antiviral medications like Tamiflu and Paxlovid are more effective when given within the first two days of symptoms.

Adoption Takes Time

While the new tests are available, experts note that adoption takes time. Mara Aspinall, a professor of practice in biomedical diagnostics, says that she has seen these combo tests in every pharmacy she has entered this season, but purchases have only increased in recent months. The cost of the tests, which are not covered by insurance, may be a barrier for some people.

Stay Informed and Stay Healthy

As flu cases continue to rise, it's essential to stay informed and take steps to protect yourself and your loved ones. By using the new over-the-counter tests and following the guidance of healthcare experts, you can help prevent the spread of illness and get the treatment you need if you do get sick. Remember to isolate yourself if you test positive, and don't hesitate to contact your doctor if you have any concerns. Stay healthy, and stay informed!
