a host to survive. Humans are the primary hosts for the virus and the virus is extremely transmittable by way of person-person contact (most commonly fecal-oral contact). Although the virus is extremely contagious‚ the human immune response can be considered a very worthy advisory in fighting polio. Most of those infected will not experience any symptoms‚ and only a very small percentage of those who do will develop paralysis from the virus. There are three known strands of the poliovirus‚ commonly

The usual diagnosis of this condition is based on reported symptoms and a physical exam. Although

found to be caused by this virus. The virus was then named the Norwalk virus or agent. It was first classified as a small round virus. Then later after genetic studies in 1990 the molecular cloning of the Norwalk virus genome led to the classification of this virus into the family Caliciviridae‚ then its name was eventually changed to the Norovirus. There are 5 geno groups of this virus and they are GI‚GII‚GIII‚GIV‚ and GV which is determined by the RNA sequence of the virus. Only genotypes GI‚ GII

organisms is the virus called rabies. Since Rabies is spread through a virus‚ we will discuss how viruses work. With the many different types of viruses‚ there are different ways that viruses affect the body. Essentially most cells have both DNA and RNA. These are the building blocks of life. When cells split in half‚ the genetic material that is there is copied and then transferred to each call. As Mike Redde explains‚ “Viruses on the other hand‚ are one-celled that only have

It may also spread from person to person through infected body fluids. Zika first occurred in Africa‚ but it has recently spread to new areas. The virus occurs in tropical climates. The location of Zika continues to change. Most people who become infected with the Zika virus do not have serious illness. However‚ Zika may cause birth defects in an unborn baby
