Introduction
Influenza B is a virus that is related to the flu, and it is one of the most common causes of fever in humans. It is spread through the air when a person coughs or sneezes, and it can also be spread by contact with an infected person or object. The symptoms of influenza B include fever, headache, sore throat, and body aches. In some cases, the virus can cause more severe symptoms, such as bronchitis or pneumonia.
How Long Does a Fever From Influenza B Last?
The length of a fever from influenza B varies from person to person. Generally, a fever from influenza B can last from three to five days. However, some people may have a fever that lasts for up to two weeks. It is important to note that the fever may not be continuous, and it may come and go during the course of the illness. Additionally, it is possible for the fever to return after the initial fever has been resolved.
Treatment and Prevention
The best way to treat a fever from influenza B is to rest and drink plenty of fluids. Over-the-counter medications such as ibuprofen or acetaminophen may help to reduce the fever and relieve some of the discomfort associated with the virus. It is important to note that antibiotics are not effective for treating influenza B, as it is a virus and not a bacterial infection.
The best way to prevent the spread of influenza B is to practice good hygiene, such as washing hands regularly and avoiding close contact with people who are sick. Vaccination is also recommended for those who are at high risk of contracting the virus.
