Is Smallpox a virus or bacteria?

Is polio an RNA virus?

Poliovirus, the prototypical picornavirus and causative agent of poliomyelitis, is a nonenveloped virus with a single-stranded RNA genome of positive polarity. The virion consists of an icosahedral protein shell, composed of four capsid proteins (VP1, VP2, VP3, and VP4), which encapsidates the RNA genome (1).

What type of virus is coronavirus?

Coronaviruses are a type of virus. There are many different kinds, and some cause disease. A coronavirus identified in 2019, SARS-CoV-2, has caused a pandemic of respiratory illness, called COVID-19.

What type of virus is the smallpox virus?

Smallpox is an acute, contagious disease caused by the variola virus, a member of the genus Orthopoxvirus, in the Poxviridae family (see the image below).

Is diphtheria a virus or bacteria?

Diphtheria is a serious infection caused by strains of bacteria called Corynebacterium diphtheriae that make a toxin (poison). It is the toxin that can cause people to get very sick. Diphtheria bacteria spread from person to person, usually through respiratory droplets, like from coughing or sneezing.
