All viruses are not: All viruses are not the same.There are viruses that effect respiratory system, others effect stomach and GI tract, they cauise different symptoms in different age groups.How long a person is contagious also depends on the type of virus and the body system it effects.Weakness and fatigue is common to most and can last after the infection has cleared up.
