10 Signs And Symptoms Of Influenza A To Know

Fever 

The immune system will start an attack to eliminate the source when an infection, such as those caused by influenza, arises. The ordinary course of this reaction includes a rise in body temperature.

Usually, the fever goes away on its own. However, a severe infection that requires medical attention could be indicated if the body temperature increases excessively. In this situation, a doctor might suggest medicine to lessen it.

Most kids and adults find having a fever uncomfortable. The bad news is that it typically isn’t a cause for alarm. Infants may have a severe infection even with a mild fever.

Although everyone’s average body temperatures vary, they often fall between 97°F and 99°F (36°C to 37°C). A person has a fever when their body temperature reaches 100.4°F (38°C) or above.

The hypothalamus, a brain region, regulates body temperature. For example, the hypothalamus can reset the body’s temperature to a greater level in reaction to an infection, disease, or other reason. Therefore, when a fever appears, something is wrong with the body. Fevers can be caused by several conditions, such as an infection, strep throat, influenza viruses, chickenpox, pneumonia, or COVID-19.
