How are the "incubation period" and "window period" of HIV distinguished from each other?

Difference: Incubation period: time when the person is first exposed to the virus to the time when the diesase start to manifest itself window period: time it takes for the test used to diagnosed the disease can reliably detect the disease; in HIV the elisa test is used to detect an antibody against the virus, it takes around 2-6 weeks for the immnune system to produce it, during this period elisa is (-). ...Read more

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

What is the incubation period for aids?

What is the incubation period for aids?

HIV infection: This is probably the wrong question. There is no 'incubation' period. If you get infected with HIV you are infected with HIV and must be treated to prevent the immune destruction that leads to aids. Now, from exposure to full on infection is usually a fourteen to twenty-one day process. The new HIV viral tests can be 100% accurate at day 21 or later. ...Read more

What is the incubation period for flu this fall?

Average 2 days: The typical incubation period for influenza is 1—4 days (average: 2 days). Adults shed influenza virus from the day before symptoms begin through 5—10 days after illness onset. However, the amount of virus shed, and presumably infectivity, decreases rapidly by 3—5 days after onset in an experimental human infection model. ...Read more

What is the incubation period for Syphilis? As far as test reactivity is concerned.

What is the incubation period for Syphilis? As far as test reactivity is concerned.

Tricky syphilis: Syphilis can appear one week to THREE months after an exposure. Part of that has to do with how many bacteria came across at the time of infection. Obviously if there were alot of those germs, the infection would get started earlier than otherwise. Serological or blood testing should parallel those symptoms- it gets more complicated though when exposures were in the past. An ID doc can help. ...Read more

Can pityriasis rosea be spread from person to person? What is the incubation period?

Can pityriasis rosea be spread from person to person?  What is the incubation period?

Presume "no": The cause of pityriasis rosea is unknown, but it may be a virus (because sometimes several people get the rash around the same time). If it is due to a virus, the way it is transmitted from one person to another is also unknown. So, the rash is not considered contagious. It goes away by itself in about 6 weeks. If worried, or in a special situation, one should discussed it with his doctor. ...Read more

I have read that cats with rabies during incubation period will not pass on rabies. Is it true? I'm very worried.

Rabies and cats: An animal might 'shed' viruses and therefore be infective before actual symptoms are shown. For dogs and rabies, we know this can occur up to 6 days before the dog shows real symptoms of rabies. So if there's any question, it's best to find the cat and isolate it. Then, if in 10 days the animal develops rabies you will have your answer. Animals bites, esp. cats, should be evaluated by a doctor. ...Read more

If you touch someone with herpes can you prevent it before the incubation period can you just wash the part of where you touched it?

If you touch someone with herpes can you prevent it before the incubation period can you just wash the part of where you touched it?

Washing usually helps: Viruses gain access through any open skin wound. If you have a cut or an insect bite it is a potential portal of entry for any type of virus to set up housekeeping and cause trouble. Of course you're not going to end up with the herpes virus unless you have direct contact. ...Read more

What is the incubation period of n fowleri? Why do some sites say 1-7 and others go up to 15 days? Seems most cases are 7 or less when symp show

Too rare to worry: Naegleria fowleri encephalitis is so rare that only a few cases have been studied, so it is understandable that estimates of incubation period may vary widely. But it really shouldn't matter. You cannot have it if you haven't been swimming in freshwater ponds or lakes. Even if you have done that, there are only an average of 1-2 cases per year in the entire US. You aren't likely to be one of them! ...Read more
