When attending social gatherings, such as parties or weddings, it's not uncommon to worry about catching the flu if someone nearby is coughing and sneezing. If symptoms appear less than 24 hours after exposure, it is unlikely that you contracted the virus from them.
The flu virus spreads easily through droplets in the air when an infected person coughs, sneezes, or talks. Symptoms typically develop one to four days after exposure. Individuals are most contagious on the third or fourth day of showing symptoms, which is also when symptoms are most severe. Once a person has been fever-free for 24 hours without medication, they are generally no longer contagious.
Flu season runs from October to May each year. Over-the-counter medications can help alleviate symptoms like fever and body aches. Prescription antiviral medications such as Tamiflu (oseltamivir) can reduce symptom severity and duration if taken within 24 hours of onset. Tamiflu can also prevent the flu in high-risk individuals who have been exposed.
Tamiflu's disadvantages include its need for early administration and potential side effects like upset stomach and irritability. The cost may be significant depending on insurance coverage.
While rare, it is possible to catch different variants of the flu in one season. There is no quick cure for the flu; staying hydrated helps support recovery.
Preventive measures include washing hands with soap and water, avoiding touching your face, and wearing masks in crowded places. The flu poses serious risks, especially to vulnerable populations like the elderly or those with pre-existing health conditions. It remains important to take precautions seriously and stay home when sick to protect others.
