Fever
One way to tell the flu apart from other seasonal viruses and infections is the presence of a fever. Usually, the common cold will never generate a fever. The reason fevers are prominent is due to the immune response. Viruses like the flu can proliferate in temperatures close to normal body temperature (98.6 degrees F) but perish under more intense heat.
Although fevers are uncomfortable, a low grade fever can be beneficial to fighting off the virus. Low grade fevers between 98.7 and 100.4 degrees F are usually not a concern for children and adults. However, if your fever goes above 102 degrees F, you will need to bring the fever down. Temperatures above 105 degrees are considered dangerous, and anything higher than 107.6 degrees F can cause brain damage.
Treat your fever with medications like acetaminophen, aspirin (adults only), and ibuprofen (can be taken after 6 months old); drink plenty of fluids; take a lukewarm shower or bath; and avoid dressing with too many layers, since this can artificially increase your body temperature.
