Is the flu the same as a cold?: The flu and common cold, while sharing similar symptoms, are caused by different viruses and vary in severity. The flu can cause more severe symptoms like deep coughs and systemic issues such as fever and muscle aches, while the common cold is generally milder.
Does cold weather cause the flu?: The flu vaccine does not increase the risk of contracting the virus; in fact, it's designed to build immunity and protect against the flu. Getting vaccinated is crucial because the flu's composition changes yearly.
Are there medications to cure the flu?: Antiviral medications like Oseltamivir (Tamiflu) can treat the flu, but their effectiveness isn't guaranteed for all cases and is typically reserved for high-risk individuals. Antibiotics are ineffective against viruses.
What can I do to protect myself during flu season?: To stay safe during flu season, practice good hygiene such as washing hands and covering coughs. Get the flu vaccine, especially if you are in a high-risk group, and stay home if you feel sick.
Does the flu vaccine increase the risk of getting the flu?: Cold temperatures themselves don't cause the flu. However, winter's lower humidity and increased indoor gatherings create conditions that favor flu transmission.
