Human immunodeficiency virus--can it mutate?

Human immunodeficiency virus--can it mutate?

Yes: Hiv mutates in response to HIV therapy. If you're being treated without a complete response (partial suppression), the virus can mutate so it can replicate in the presence of the drugs. This usually happens in people who don't take their medications properly. They can then transmit the mutant virus to others. Spontaneous mutation (mutation independent of therapy) has not been a big problem. ...Read more

Is human t cell leukemia/lymphotropic virus (htlv-1) contagious?

Yes: Both htlv-1 and htlv-2 are spread by sexual transmission, from mother to child, and by exposure to infective blood through transfusions and injection drug use. In this respect the virus is contagious. It does not appear it is transmitted in any other way. ...Read more

Test for or infection with human immunodeficiency virus hiv?

Test for or infection with human immunodeficiency virus hiv?

HIV testing: There are several HIV tests. We usually check what is called an elisa blood/oral test. It's very sensitive & specific but misses early, early infection (<15-20 days). In us we confirm a + elisa w/a test called a western blot (looks for HIV specific proteins). Other countries just use elisa x2. For acute HIV infection we measure viral RNA in blood. Can be falsely + so needs expert evaluation. ...Read more

In what viral group is human papilloma virus classified?

In what viral group is human papilloma virus classified?

HumanPapillomaVirus: Human papilloma viruses is the name of a large group of viruses. There are about 100 subtypes of human papilloma viruses; almost half can occasionally cause cancer. For example, the virus that causes ordinary skin warts (including plantar warts) is called hpv-1. Two others, hpv-16 and hpv-18, are responsible for a majority of cervical cancers and are components of both of the hpv vaccines. ...Read more

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

Cellular immunity: These are cells that work as part of the cellular immune system, fighting certain fungal (e.g. Cryptococcus), viral (e.g. Herpesviruses), parastic (e.g. Toxoplasma), and bacterial (e.g. Tuberulosis) infections. The cellular immune system also helps to prevent certain cancers, such as lymphomas. ...Read more

Does G6PD deficient individual has any immunity from Ebola virus?

Does G6PD deficient individual has any immunity from Ebola virus?

Not aware of any: studies that suggest that G6PD deficiency offers any immunity to Ebola. My concern would be that these people could be at risk of reactions to treatment venues that might be provided if they are infected with Ebola. ...Read more

How is the human immunodeficiency virus (hiv) transmitted to heterosexuals?

How is the human immunodeficiency virus (hiv) transmitted to heterosexuals?

Same as heterosex: Hiv is transmitted by the virus present in body secretions deposited onto areas of either mucous membranes (rectal mucosa, oral mucosa or tonsils) where there are receptor sites to which the virus attaches. There are some forms of sexual activity in which individuals are more prone to bleeding, in which case these bleeding sites present a rapid route for viral entry. ...Read more

Hepatitis b antibody.Standard 5 item HBV test, only HBV surface antibody present. How immune is this to a partner of HBV carrier status through sex?

Hepatitis b antibody.Standard 5 item HBV test, only HBV surface antibody present. How immune is this to a partner of HBV carrier status through sex?

Foolish: If someone is actively and acutely infected with hep b, even the idea of considering unprotected sexual intercourse is ridiculous. Just because immunization status shows immunity to hep b, this is not a 100% guarantee and there are still risks. ...Read more

Does the eb virus cause infectious mononucleosis?

Yes: The epstein barr virus (ebv) causes mononucleosis. After infection, it stays in the body for life. If the infection occurs in early childhood, the illness will be similar to the common cold. Most people have been infected by the ebv virus by the time they reach adulthood. ...Read more

What type of cell does herpesviridae (herpesvirus) infect in humans?

What type of cell does herpesviridae (herpesvirus) infect in humans?

Skin cells: The herpes virus comes in 2 types: herpes simplex (hsv) 1&2. Antibodies (igg) to both viruses can be tested to see if you have lasting immunity and (igm) short-term antibodies check to see if you have had a recent infection. Unfortunately the igg levels can not tell how long ago you were exposed. Also herpes 1 & 2 viruses can cause either oral or genital herpes. Hope that helps. ...Read more

How did human immunodeficiency virus (hiv) evolve?

How did human immunodeficiency virus (hiv) evolve?

Evolution: It came from a simian precursor transmitted to humans by one of several mechanisms. This virus mutates continuously and the form to which it mutates which is best capable of surviving under the circumstances is the one which will be reproduced and multiply within infected cells. Unless of course you are a creationist. ...Read more

Hsv type1 IgG antibdy=0.41, HSV type2 IgG antibdy= 0.41 is this means negative? Helicobactef pylori =3.91, is this transmitted disease too?

Hsv type1 IgG antibdy=0.41, HSV type2 IgG antibdy= 0.41 is this means negative? Helicobactef pylori =3.91, is this transmitted disease too?

Serologies: Am not familiar with the lab values that you are using. Each laboratory may put out differing results depending upon the test they use. Almost everybody (>93%) has hsv in their body. H. Pylori, if you have it, can be easily treated and eliminated. ...Read more
