Flavivirus

BACKGROUND Hepatitis C virus (HCV) is a major issue in today’s society. This flavivirus infection was discovered in 1989, before which it was called a non-A, non-B hepatitis. The world health organization (WHO) estimates that 3% of the world’s population has already been infected with HCV and there are almost 170 million carriers who

by Japanese encephalitis virus (JEV) belonging to the family Flaviviridae (Cha et al., 2014). The Japanese encephalitis virus cause significant morbidity and mortality by infecting CNS and spinal cord. Japanese encephalitis virus (Flaviviridae, Flavivirus) is an enveloped virus having 40–50 nm in diameter and it contains single stranded RNA as genome (Vashist, Bhullar, & Vrati, 2011). JE was first reported from Japan as a clinical entity in 1817 later the JEV was isolated in 1934 from a fetal human

Nile Virus (WNV) was originally detected from a woman in Uganda in 1937. WNV first appeared in the United States in 1999 in New York which was the first incident in the Western Hemisphere. WNV is a mosquito-borne virus (arbovirus). It is in the flavivirus family. WNV is a neurotropic virus. WNV is a member of the Japanese encephalitis virus. Severe encephalitis outbreaks in humans have been escalating. The means by which the virus gains access to the brain (also known as neuroinvasion) seems

The Country’s Overview Philippines is an archipelago located in Southeast Asia near the equator. The Philippine archipelago consists of 7,107 islands divided into three major groups of islands which is Luzon, Visayas and Mindanao. As of 2016 the Philippine population is estimated to about 102,624,209 (World Fact Book). The Philippine nationality is termed Filipino and its population is made up of various ethnic groups. The national language is called Tagalog, it also the name of the major ethnic

According to the CDC (2015), the Japanese encephalitis virus is a flavivirus just like the yellow fever and West Nile virus. Flaviviruses are mostly transmitted through bug bites, such as an infected mosquito.

It reminded everyone of the 1999 West Nile virus because of the similarities amongst the symptoms of the two viruses. Contrastingly, Zika Virus has a slightly different mode of transmission. The virus is a member of the flaviviridae family and flavivirus genus and is a positive, single stranded, RNA virus (Kuno, 1). Zika Virus has been known to severely affect pregnant women. In pregnant women, Zika Virus causes a birth defect resulting in abnormally small brain sizes in babies called microcephaly

Most people don’t know that 10% of people that get Yellow Fever die from it. However some viruses are more harmful than others which may scare some people. The many symptoms of Yellow Fever may make this viral infection seem frightening even though there is a treatment available, the history is quite unique, but how it is spread may surprise people. There are two different conditions of Yellow Fever, mild and severe. Mild cases’ symptoms include fever, headache, nausea, back pain, body aches

3. BACKGROUND AND LITERATURE REVIEW 3.1 INTRODUCTORY STATEMENT Aedes albopictus is considered to be the most invasive mosquito species in the world (1, 2) and there is an increased potential for its introduction into mainland Australia given the established populations discovered, since 2005, in the Torres Strait, the region that sandwiches between Papua New Guinea (PNG) and northern Australia (3). The aedine mosquito species have been culpably involved in the transmission cycles of pathogens of

The Zika virus was first discovered in 1947 in a rhesus monkey in a forest in Uganda. This virus also known as ZIKV, is a type of Flavivirus, which is a form of a fast evolving RNA virus. From there, Zika was then discovered all around the African continent in countries such as Nigeria (1971, 1975), Sierra Leone (1972), Gabon (1975), Uganda (1969, 1970), Senegal (1988-1991) and Côte d’lvoire (1999). Additionally, Zika was also discovered in Asia as well. Cities like Pakistan, Malaysia, Indonesia
