Why does the virus that causes shingles become active again in some people?

Interesting: Usually for reasons we don't understand the varicella-zoster virus that causes chicken pox decides to reactivate later on and cause shingles. This usually happens after age 50, likely due to a weakened immune system as we age. Some other possible triggers are trauma, physical or emotional stress. ...Read more

Does encephalitis just happen at any time? The virus you had in the past is dormant in your system then transfers and infects the brain of some people? Or does it more commonly happen in the new infections of the virus' ?

Does encephalitis just happen at any time? The virus you had in the past is dormant in your system then transfers and infects the brain of some people? Or does it more commonly happen in the new infections of the virus' ?

Confusing question: The wording of your question is hard to follow. That said, there are some basics I can state. Most encephalitis viruses burn out and are essentially eliminated by the immune system.There transfer process is type specific, some in saliva during the illness, some by mosquitoes, once healed, you do not pass the virus to others. ...Read more

True that you are less likely to get hsv1 in the genital area(oral sex) if you already have it in the mouth area? What are symptoms of genital hsv1?

True that you are less likely to get hsv1 in the genital area(oral sex) if you already have it in the mouth area? What are symptoms of genital hsv1?

Yes it's true: I think this is your third question. People are immune (or at least highly resistant) to new infections with the HSV type they already have, anywhere on the body. Symptoms are identical for HSV1 or HSV2, typically with blisters that become painful sores, first infection often with swollen lymph nodes nearby, sometimes fever. Genital HSV1 usually causes far fewer recurrent outbreaks than HSV2. ...Read more

Is it true that HPV vaccine will prevent new precancerous lesions even in people already infected with HPV? I read this in several articles.

Yes and no: HPV vaccine contains several different strains of the virus. It depends which strains you have been infected with already. You can be tested for the specific HPV strains subtypes and if - it could protect you against those. You most ALWAYS use protection and insist on it. It's your life you know! ...Read more

If HPV is possitive for two couple can the immune system clear it of or it makes it harder because they are sharing hpv?

If HPV is possitive for two couple can the immune system clear it of or it makes it harder because they are sharing hpv?

Its a virus: HPV is a virus & in asymptomatic people, it can go unrecognized. Treatment is geared toward the symptoms (genital warts or cervical cancer) when present but not for the virus itself. Like any virus, it clears up on its own; however, recurrent exposure increases the chances of developing symptoms over time. ...Read more

Do people have antibodies to the brain eating amoebas since they're so common in the environment but rarely infect people ?

Yes: Several facets of the immune system including barrier function are involved in the host's defense against amoebas. Antibodies like IgA on mucosal surfaces can slow migration but other responses like the complement system and white blood cells are more involved. Not everyone's response is equally adept however and amoebas have evolved ways to resist the immune system. TMI ? ...Read more

Is it true that the molluscum contagiosum virus can stay in body for a year even after all lesions are completely gone? If so can it still be transmit

Is it true that the molluscum contagiosum virus can stay in body for a year even after all lesions are completely gone? If so can it still be transmit

No: Molluscum is on skin only. Once the lesions are removed it does not recur. All the lesions need to be removed either by liquid nitrogen, Aldara (imiquimod) or curetting off. If removed , it may require 2-3 sessions because there are small molluscum lesions that are not visible at first. They surface in 3-4 weeks. Molluscumrx is an herbal which can be used at home. ...Read more
