Flavivirus

Herd immunity is the form of immunity that directly occurs as a result of individuals who are vaccinated versus those who are not. In a given naive population, the west nile virus can spread randomly throughout individuals, with the contact of each other only accelerating the spread. In a population where half has randomly received some form of vaccination, certain barriers between those that are vaccinated can protect specific individuals who have not been vaccinated against the spread of the virus

number :1065211 Unit : medical microbiology DESIRE IRAFASHA Yellow fever Yellow fever is defined as an acute haemorrhagic fever, sometimes associated with extensive hepatic necrosis and jaundice. The disease is said to be caused by insect-borne flavivirus that is also a single stranded RNA virus. (Strayer, R. R. D. (2011).Yellow fever virus is an Alpha virus belonging to the Flaviridae virus family that uses primates as monkeys as its primary reservoir and transmitted to hosts such as humans using

governments to clean up their city and take precaution. For example, making sure the sewers were clean and eliminating mosquitoes. But before we get into this topic we must know what Zika is. What is Zika The Zika is an extremely rare disease; a flavivirus transmitted by mosquitos, the Genus Aedes, which was discovered in 1947 in Uganda. Despite that it is mainly seen in the Aedes, it was first seen in rhesus monkeys located in the forest also known as Zika forest. Many that are bit by the mosquito

estimated 2.5 billion people are at risk and an increasing trend in annual number of cases over recent reported years (1,2). The dengue virus (DENV) is a small, positive, enveloped RNA virus about 40-50 nm in diameter. DENV belongs to the genus flavivirus; a member of the Flaviviridae family (1). Its single-stranded genome codes for three structural proteins (capsid, precursor membrane, and envelope), and 7 non-structural proteins. There are four different serotypes of the virus, DENV-1 through DENV-4

outbreaks. Through all the Yellow fever cases around thirty thousand of them led to death. Yellow fever was thought to have originated in Africa and was brought to America on the slave ships. The virus is a single-stranded RNA virus that belongs to the flavivirus senes. After the transmission of the virus occurs, it replicates in religion lymph nodes and silently spreads through the bloodstream. The widespread dissemination can affect the kidneys, lymph nodes, spleen, liver, and bone marrow. In addition

To identify the spread of every infectious disease known to infect the human population is problematic. The whereabouts of how certain viruses migrated from its known origin in the Eastern Hemisphere over to the Western Hemisphere is still unclear in relation to West Nile virus (Nelson & Williams, 2014). There are only theories behind the routes on how the virus spread to North America, perhaps the migration of birds infected with West Nile virus, or through the means of creating bioterrorism of

West Nile Virus is a viral disease that is transmitted by mosquitos. West Nile is a virus that reacts very differently depending on the person that is infected with it. In fact, most people do not ever develop symptoms after being infected by the West Nile Virus via a mosquito bite. That means 70-80% of all people are asymptomatic after contracting this disease (Centers for Disease Control Website, 2015). That is a large number of people that do not present with any symptoms which to me that means
