get genital herpes. You get genital herpes by having vaginal, anal, or oral sex with someone who has the disease. Fluids found in a herpes sore carry the virus and contact with those fluids can cause infection. You can also get herpes from an infected partner who does not have a visible sore or who may not know he or she is infected because the virus can be released through your skin and spread the infection to your partner. The only way to avoid STDs is to not have vaginal, anal, or oral sex.…

a sexually transmitted infection caused by Herpes Simplex Virus. This virus affects the genitals, cervix, and skin in other parts of the body. Herpes is a chronic condition but many people never have symptoms even though they carry the virus. HSV-1 is the most common causing oral herpes but can cause genital herpes through oral to genital contact. HSV-2 is primarily transmitted through sexual contact. The symptoms of herpes simplex virus are typically blisters or multiple bluster in the infected…

family of this virus also. The structural composition of this cell is a core, capsid, and its spikes (POWERPOINT). The core is the inner most layer of the virus, but what determines the location of the virus is the spikes on the exterior part of the virus (POERPOINT). Once the spike s find the precise fit to the receptors it’ll attach then go forth with entry (POWERPOINT). The cells that the papillomaviridae spikes will be housed only in skin and mucosal cells (WHO). This DNA virus doesn’t…

CDV is an enveloped, non-segmented, single-stranded RNA virus and is a member of the Morbilliviruses, thus closely related to measles virus (LAMBandKOLAKOFSKY 2001; VANDEVELDE and ZURBRIGGEN 2005). CDV possesses a nucleocapsid containing the viral genome, which consists of the nucleoprotein (N) and the polymerase complex including the (P) and (L) proteins (DEMETER et al., 2007). The membrane protein (M) is located at the inner surface of the envelope, which exhibits two surface glycoproteins:…

Measles and Krippin virus stem from the same family but are radically different. Both viruses have a (-)ssRNA genome, as KV is developed from MV. Due to the common origin, there are similarities, however, one of which being developing a cancer treatment for each virus. In KV, the measles virus was genetically modified to target and kill cancer cells. As Alice Krippin states, in 10,009 clinical trials, there were 10,009 cancer-free patients (Lawrence). In Measles, the virus targets cells…

Influenza is one of the major respiratory virus that causes nearly annual epidemics and occasional pandemics. Influenza epidemics generally occur in the winter months in the Northern hemisphere and May-September in the Southern hemisphere (Cox et al, 2004). This virus belongs to the genus Orthomyxovirus in the family of Orthomyxoviridae. Influenza A viruses are enveloped RNA virus with eight RNA segments that encodes for upto 11 viral genes ( Lamb &Krug ,2001, Fields virology, 4th edt. ).The…

The 1918 “Spanish flu” Pandemic was caused by an avian-like influenza virus that gained the ability for efficient and sustained human-to-human transmission and then spread globally, killing 20-50 millions. Fortunately, viruses with pandemic potential are rare occurrences and ongoing surveillance of human and avian viruses is being done globally in preparedness for an influenza pandemic. Vaccines and anti-viral drugs may be available, if needed and time permits. Both kinds of therapies have…

A virus is a small infectious agent. There are different types of viruses. Viruses are all over the world and can be caused by many things and substances. Viruses are nonliving, it contains genetic information, has to survive (DNA/RNA) in a host, and can multiply from 1 virus to 1,000. Viruses have 3 components. Capsid surrounds DNA, Tail sheath-connected to capsid, and tail-fibers-connected to the sheath. The virus DNA travels down the tail sheath through the membrane. The virus tricks the cell…

body, creating health hazards as minor as the common flu and as disastrous as the AIDS epidemic. Viruses have many types; one is an RNA virus. RNA virus is a virus that has RNA as its genetic material. One of the human diseases that is caused by RNA virus is the Ebola virus. In order for someone to be infected by Ebola, one must come into contact with the virus. It can enter the human body through the nose, mouth or breaks in the skin. Once inside, it finds a host cell to infect. The viral…

first occurrence of the Lassa virus was in 1969, even though it was unbeknownst to the person who contracted it at the time. While in a village named Lassa that was located in Nigeria, missionary Laura Wine contracted a mysterious disease after taking care of a patient that was giving childbirth. It wasn’t until samples of the virus were sent to be researched at Yale University that scientists and virologists alike realized that they were looking at an entirely new virus. Unfortunately, Laura…
