Flu or influenza (caused by influenza virus) is a miserable experience as it daunts the victim with countless sneezes, head aches and fever.
Flu develops when tiny droplets coughed or sneezed into the air by an infected person are inhaled by an uninfected person. Flu is often confused with common cold. But, they are different, though certain flu symptoms are the same. According to the University of Maryland Medical Center, fever and muscle pain associated with flu goes away with prevention and treatment in a day or two, however, fatigue may last for a week.
