Epstein Barr Virus
Transcript of Epstein Barr Virus
It is one of the most common viruses in the world. Affects 95% of adults between the ages 35 and 40. In the United States and in other developed countries, many persons are not infected with EBV in their childhood years. When infection with EBV occurs during adolescence or young adulthood, it causes infectious mononucleosis 35% to 50% of the time. Fever
Swollen lymph glands
Swollen lymph nodes in the neck Symptoms To reproduce the EBV has to use a host cell. For the Epstein-Barr virus the host cell must be that of a human, more specifically lymphatic cell or an epithelial cell in the mouth. It can reactivate quietly without causing symptoms and may contaminate saliva. Healthy people can spread the virus to uninfected people through kissing or sharing food known as the "kissing disease." How it Reproduces and is Transmitted The Epstein-Barr virus is made up of spikes, an envelope, a core, capsid, and tegument. The spikes help attach the virus, the envelope protects the outer membrane, the core holds the double-stranded DNA and is enclosed inside all of the other structures. Capsid protects the core and the tegument is the space between the capsid and envelope. The EBV genome isolated from virus particles is a linear, double stranded DNA molecule of about 175 kilobase pairs (kbp). Discovery The host range of EBV is restricted to humans and certain subhuman primates including squirrel monkeys and cotton top marmosets.It occurs most often in young adults between the ages of 15 and 35 and is especially common in teenagers. Consuming L-lysine makes it easier to control outbreaks of mono, epstein barr, and herpes viruses. Consuming foods that contain large amounts of lysine and restricting foods high in arginine is also extremely helpful in fighting the Virus. . Rest, fluids, and over-the-counter pain medicines are recommended .

In 1968, the virus was linked to the disease infectious mononucleosis. Infection with Epstein-Barr virus (EBV) is very common and usually occurs in childhood or early adulthood. might soon be stoppable! Research scientists are currently testing primates (not humans yet) with a new vaccine that uses recombinant DNA to stimulate antibody responses by your immune system! This would only help individuals who have not yet been introduced to Mono however.
can be fatal! Yes, although EBV is generally benign there are cases where individuals are very sensitive to the virus.
is interlinked with nasopharyngeal cancer in Asia. Rarely do cancers form from the Epstein-Barr virus in the United States even though at least eighty percent of the population will become infected during their lifetime.
