The duration of a flu can vary from person to person. Generally, the flu will last from one to two weeks. However, it can last longer in certain cases, especially for those with weakened immune systems.
For most people, the worst symptoms of the flu will usually last for three to five days. During this time, you may experience fever, body aches, chills, fatigue, and sore throat. During the first two days of the flu, you may also experience a runny nose, nasal congestion, and a dry cough.
After the initial symptoms subside, some people may experience lingering symptoms for an additional week or two. These may include fatigue, congestion, and a mild fever. In some cases, these symptoms may not completely go away until two to three weeks after the initial onset of the flu.
If the flu persists for longer than two weeks and is accompanied by a fever, it is important to consult with a doctor. This is especially important if you experience other symptoms such as chest pain or shortness of breath.
In conclusion, the length of the flu can vary depending on the individual. The majority of people will experience the worst symptoms for three to five days, while others may experience lingering symptoms for two to three weeks. If symptoms persist for longer than two weeks, it is important to consult with a doctor.
