The majority (80%) of patients with group A streptococcal toxic shock syndrome have symptoms of a soft-tissue infection (pain, redness, warmth, swelling) in an area just below the skin or in a muscle.
The symptoms of influenza are usually more severe than the symptoms of a common cold. Symptoms typically develop one day to seven days after exposure, and can last from a few days to two weeks. They may include any or all of the following: 1  Fever (usually 100Â°F or warmer, lasting for several days).
The time between the exposure to the virus and the symptoms to appear is called the incubation period. The normal incubation period for flu is about 3-5 days. After the incubation period, you start displaying symptoms and excreting enough viruses to infect people around you. It will start with a mild headache, but the next day, you will have a few aches with a low fever. It will turn into a high fever on the third day with a runny nose.
