Detailed explanation-1: -HIV and Ebola are both viruses. Both emerged in Africa, Adalja noted, neither has a vaccine, and both are fatal if left untreated. Both are carried by host animals and then transmitted to humans, and both may have made that transition when hunters ate bush meat.
Detailed explanation-2: -Ebola is a virus that causes severe inflammation and tissue damage throughout the body. It is known as a hemorrhagic fever virus, because it can cause problems with the clotting system of the body and lead to internal bleeding, as blood leaks from small blood vessels.
Detailed explanation-3: -Still, viruses have some important features in common with cell-based life. For instance, they have nucleic acid genomes based on the same genetic code that’s used in your cells (and the cells of all living creatures). Also, like cell-based life, viruses have genetic variation and can evolve.
Detailed explanation-4: -Common viral illnesses include colds, the flu, COVID-19, norovirus (“stomach flu”), HPV (warts) and herpes simplex virus (cold sores). Many viruses go away on their own, but some cause life-threatening or chronic illnesses.
