Epidemiology of Rubella NUR 408 August 6‚ 2012 Epidemiology of Rubella Pregnant women are one vulnerable group susceptible to contracting a viral disease. One viral disease that pregnant women can contract is rubella. Rubella is often a mild disease that affects children‚ adolescents‚ young adults‚ and is susceptible to pregnant women. The disease can be devastating when transmitted to the fetus. This paper will discuss the definition and description of epidemiology as well as the steps and

Symptoms Rubella symptoms do not typically present until day 7 to 14 of the infection2. At first‚ the infected person will exhibit no symptoms but they are still contagious. Typically‚ the first perceptible symptom is inflamed lymph nodes behind the ears. Before symptoms appear‚ the virus incubates in the host for approximately one week before becoming outwardly apparent. The first sign is a rash that appears after a week of incubation and only lasts for about three days. This rash will start

A virus is a small infectious agent that can replicate only inside the living cells of an organism. Viruses can infect all types of organisms‚ from animals and plants to bacteria and archaea.[1] Since Dmitri Ivanovsky’s 1892 article describing a non-bacterial pathogen infecting tobacco plants‚ and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898‚[2] about 5‚000 viruses have been described in detail‚[3] although there are millions of different types.[4] Viruses are found in

Ebola Virus— What type of virus is it? How it spreads? What is being done to contain its spread? What treatments are available? Ebola genome is a single-stranded RNA approximately 19‚000 nucleotides long. It encodes seven structural proteins such as nucleoprotein‚ polymerase cofactor‚ transcription activator‚ RNA- dependent RNA polymerase. The Ebola virus is a Filovirus. These virus types cause fever or cause bleeding inside and outside the body when having a very high fever. Ebola

rabies virus is in the family Rhabdoviridae in the Mononegavirale order of viruses. The rabies virus is usually bullet-shaped and is made of a long single-stranded spiral chain of RNA. The virus envelope is made of matrix protein and is studded with glycoproteins. 3. People usually contract rabies after they are bitten by an animal that has been infected with the rabies virus‚ though it has been shown that in rare cases rabies can infect people who just touch infected animals. The virus spreads

The function of a capsid‚ in virus biology‚ is to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic
