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

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 moreSee 1 more doctor answer

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 moreSee 1 more doctor answer
