Why Can You Get The Flu Twice In One Season?

The flu isn’t caused by a single virus. Instead, it’s caused by different strains of the influenza virus, primarily classified into influenza A and influenza B. Within these groups, there are numerous subtypes. For example, you might get infected with one strain of influenza A early in the season and later encounter a different strain of influenza B. When you recover from the flu, your body develops immunity to the specific strain that caused your illness. However, this immunity doesn’t necessarily protect you against other strains circulating in the same season.

Factors That Can Increase Your Risk of Illness

Certain factors make it more likely to contract the flu twice in one season, including:

1. Multiple Circulating Strains: Each flu season typically sees several strains of the influenza virus circulating at the same time. If you’re exposed to a strain different from the one you initially contracted, you could become infected again.
2. Weakened Immune System: If your immune system is compromised due to illness, stress, or other factors, you may be more susceptible to a second infection.
3. Timing of Vaccination: While the flu vaccine provides strong protection, it takes about two weeks for immunity to develop fully. If you’re exposed to the flu before the vaccine has taken effect– or if the vaccine isn’t a perfect match for circulating strains– you may still contract the flu.

How To Recognize a Second Infection

Distinguishing between a second infection of the flu and other illnesses– such as a cold, RSV, or COVID-19, can be challenging. If you experience symptoms again after recovering from the flu, it’s important to consult a healthcare provider to determine whether you have contracted a new strain of the flu or if you’re dealing with something else.

Common symptoms of the flu include:

• High fever
• Body aches
• Fatigue
• Sore throat
• Cough
• Runny or stuffy nose

Prevention Strategies

To reduce your risk of getting the flu twice in one season, follow these tips:

1. Get Vaccinated: The flu vaccine is the best way to protect against multiple strains of the virus. While not foolproof, it significantly reduces your risk of severe illness.
2. Practice Good Hygiene: Wash your hands frequently, avoid touching your face, and disinfect commonly touched surfaces.
3. Maintain a Healthy Immune System: Eat a balanced diet, get enough sleep, and manage stress to keep your immune defenses strong.
4. Avoid Close Contact With Sick Individuals: This reduces the chances of encountering another flu strain.
