Your friend and you go to Central America for spring break where you have a great time (from what you can remember) except that you both get bitten by mosquitos constantly. Your poor friend comes down with malaria, has to take chloroquine, and is ill for weeks. You experience no health problems at all. You tell your friend, “Sickle-cell anemia runs in my family. That’s probably why I didn’t get malaria, too.” Your friend is not a super smart scientist like you so is utterly confused at your remark. Explain to him what you mean

Viral Infections

Viruses are abundantly found, minute entities that have genetic material enclosed within a protein coat. The proteinaceous material enclosing the genetic material of the virus is called a capsid. The genetic material could be either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). A virus is too minute to be looked at with naked eyes and therefore visualized with the help of a microscope. They are acellular entities that require a host for processes, such as replication, transcription, translation and multiplication. Plants, animals, and bacteria act as host wherein the virus reproduce. Viruses cannot multiply outside the host's body and thus are considered nonliving outside the host body.
