Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

If HIV virus won't live more than 1min the how come vaginal fluid having HIV on cloth exposed outside wiped at tip of penis can cause HIV infection?

If HIV virus won't live more than 1min the how come vaginal fluid having HIV on cloth exposed outside wiped at tip of penis can cause HIV infection?

Wrong assumption!: HIV virus can survive for weeks, outside the body, depending on the composition of the fluid containing the virus and ambient temperature. The infectivity depends on contact with skin that may have abrasions, open sore or other wounds.

Is there any way of knowing if someone is still contagious from the stomach flu? Every strain is different and some are contagious for longer?

Is there any way of knowing if someone is still contagious from the stomach flu? Every strain is different and some are contagious for longer?

No: People with viral infections are generally contagious even before significant symptoms appear. The duration other illnesses is obviously going to vary based on what virus is infecting them and therefore it's going to be different the length that they're going to be contagious. So I can't really give you specifics unfortunately. ...Read more

Is it possible to have more than 1 viral disease at the same time? With one of those being mono

Is it possible to have more than 1 viral disease at the same time? With one of those being mono

Absolutely. Immune: systems job is to constantly screen & protect from cancer cells, viruses, bacteria & fungal infections. How many we may have to fight at once varies widely & can be a huge challenge. Initial immune system response to virus (just snippets of DNA/RNA with a protein coating; no living cell) commonly takes ~7 days; thus the value of vaccines to prompt the immune system to prepare for rapid response. ...Read more

Is there different types of testosterones that will cause a rapid heartbeat a few hours after injection more than others? How can this be prevented?

Is there different types of testosterones that will cause a rapid heartbeat a few hours after injection more than others? How can this be prevented?

Not to my understand: While people react differently to different medications, there's no way of knowing in advance which testosterone will cause what side effect. All the hormone preparations list tachycardia or fast heart rate as a side effect. There's no specific way to mitigate these side effects but generic cardiac meds can be used. Talk to your prescriber or use HealthTap Prime to discuss your individual case. ...Read more

Explan why one human immunodeficiency virus test cannot definitely diagnose hiv?

Explan why one human immunodeficiency virus test cannot definitely diagnose hiv?

Good question: The HIV test to which you refer is an elisa assay which is quite sensitive but not as specific as the confirmatory western blot. These measure the presence of antibodies to the HIV and these may take from 2 wks to several months to develop. If you run the test before the antibodies have appeared, it will be negative, only to change to positive once antibody formation has occurred. ...Read more

Is it common to get Acute Myocarditis after a common cold? Specifically, more than likely a Rhinovirus. If so, is mortality high?

Is it common to get Acute Myocarditis after a common cold? Specifically, more than likely a Rhinovirus. If so, is mortality high?

No: Myocarditis is a rare disease, but not extremely rare. It does happen to people, but it is hard to find any exact numbers about it. Maybe one's chances of getting it are 1 in 5000 or 1 in 10000 people... these are just rough estimates. Likewise, it's not known how many cases are happening after Rhinovirus infections. ...Read more

I've read that carriers of group a strep bacteria can have no symptoms but can still unwittingly spread it. Others say this is not true. Which is it?

I've read that carriers of group a strep bacteria can have no symptoms but can still unwittingly spread it. Others say this is not true. Which is it?

It is true: Carriers have the bacteria in their throats and can occasionally spread it to others it does not require treatment unless you could be traced as a source of frequent infections to others. I have had lots of carriers in my practice and they have not created any epidemics.... ...Read more

What makes the steroid fungus more serious than any other strain of meningitis?

What makes the steroid fungus more serious than any other strain of meningitis?

Complex..: It is not more serious than any other meningitis but comes close in some cases. The introduction of this mold in or near the spinal fluid along with a steroid which blunts the local immune response is bad. There is very sparse information on treatment with antifungals. The organism seems to invade blood vessels causing strokes as well. ...Read more
