HIVmutates, and it does so at a constant rate. Scientists can use this rate of mutation to track the history and progress of the virus. Because of HIV's close resemblance to a simian immunodeficiency virus, researchers knew it must have originated as a virus ...
The study's authors, who also include researchers from the National Cancer Institute, hoped to answer a long-standing question in HIV biology research: How does thevirusknow to package its specific viral RNA to be copied in human cells? "Just like we need a genome encoded by DNA, viruses ...
Not only does a push for a chickenpox vaccine protect a child and his or her classmates, it can also protect grandparents who may not have had chickenpox. Protecting the elderly is also the idea behind another vaccination that many of us line up for each winter: the flu shot. Between 12,...
In order to estimate the contribution of AI to HIV and STI incidence among FSW and transmission to their sexual partners, it is first necessary to accurately described AI practice in this group. To estimate this contribution, we need data on the proportion of FSW who practise AI and at what...
How fast does the HIV viral load increase? HIV Viral Load: HIV viral load refers to how many particles of the virus are present in a milliliter sample of the patient's blood. Generally, any load above 100,000 particles per milliliter of blood is considered a high viral load for HIV. ...
How does the rabies virus reproduce? How long can a virus live outside its host's body? Explain how a vaccine would work against the virus. How do viruses replicate in the lysogenic cycle? How do cytotoxic T cells destroy pathogens? How does HIV affect the body? How long is a person ...
Studies have documented the substantial risk of human immunodeficiency virus (HIV) infection endured by sex-trafficked women, but it remains unclear how exposure to trafficking puts its victims at risk. We assessed whether the association between sex trafficking and HIV could be explained by self-rep...
Building a new virus The HIV virus is made up of 1) proteins and 2) RNA. The production of proteins from the genetic code is called ‘translation’. For the virus to replicate, it uses the cell’s machinery to produce new proteins and replicate its RNA. The cell uses the integrated vi...
(human immunodeficiency virus). Despite these hurdles, there is currently a tremendous movement to develop a vaccine to fight HIV and AIDS. The COVID-19 pandemic has resulted in millions of people being infected with the virus and hundreds of thousands of deaths worldwide. The race is on to...
