you risk infection with the Epstein-Barr virus‚ which causes glandular fever (otherwise known as infectious mononucleosis) and other nasty diseases. How does the virus work? The Epstein-Barr virus appears capable of infecting only two major cell types: the outer (epithelial) cells of the salivary gland‚ and white blood cells known as B lymphocytes (B-cells). Infection with the Epstein-Barr virus develops first in the salivary gland. Large amounts of the virus are released in the saliva‚ enabling it

not to touch anything that could have infectious material on it. Each virus also has a specific way it is transmitted to humans. The CCHF virus comes from the Nairovirus in the family Bunyaviridae. It is spread by ticks‚ more commonly the Hyalomma tick. (“Crimean Congo Hemorrhagic Fever”‚ 2012) The tick collects the virus by feeding on an infected animal and then spreads it to the next animal or human that it bites. The virus is also transferred to humans by crushing an infected tick with bare skin

The dengue virus is transmitted to humans via the bite of a mosquito. The principle mosquito species is known as Aedes aegypti. This mosquito is found all over the world‚ and‚ throughout time‚ became adapted to urban environments. For example‚ the mosquito evolved so as to be capable of living year round in moist storage containers‚ rather than relying on the seasonal patterns of rainfall. Another species‚ Aedes albopictus (the "Tiger mosquito")‚ is widespread throughout Asia. Both mosquitoes are

Advances in HIV/ AIDS Medical Research HIV (human immunodeficiency virus) is a virus that attacks the immune system‚ the body’s natural defense system. Without a strong immune system‚ the body has trouble fighting off disease. The first cases of HIV were first discovered in Los Angeles and New York in the 1980’s. A group of gay men and injection drug users were revealed to have without no known cause of impaired immunity symptoms of pneumonia‚ a type of lung infection. Soon thereafter‚ additional

order to replicate. The particular host range of a virus is determined by the virus’s requirements for attaching to the host cell and the availability‚ within the host‚ of the cellular factors needed for viral multiplication. In some viruses‚ the capsid is covered by an envelope‚ which protects the virus from the host’s nuclease enzymes. Spikes on the envelope provide a binding site for attachment to the host. Influenza virus is an enveloped virus with many glycoprotein spikes. Viruses are larger

AIDS (Acquired Immune Deficiency Syndrome) never really kills anyone; instead it is a disease like pneumonia or something like that‚ that the body cannot fight because its immune system is very weak.

Thesis The Ebola virus is one of the quickest killing viruses. The infection spreads rapidly throughout the body and is deadly to its victim. Therefore‚ it is crucial that more funds are allotted for research‚ treatments‚ and controlling Ebola outbreaks. Introduction Ebola is an illness caused by the Ebola virus. It is incredibly infectious‚ a quick killer with a ninety percent fatality rate. Sadly most of Ebola victims’ results in death that could have been prevented. The virus is spread by coming
