Does HPV stay alive on surfaces/objects? If so how long? Things like toilet, shower wand handle, and door knobs are of concern.

Does HPV stay alive on surfaces/objects? If so how long? Things like toilet, shower wand handle, and door knobs are of concern.

Here are some...: HPV particles alone are inactive, but if they gain access to cells of skin or mucosa, usually through some micro-injury to external natural barriers-skin/mucosa, which is invisible, these infective agents may replicate or be eliminated by internal humoral immune defense. So, I would throw the worry to catch HPV by the contact as described out of window of life reality, and you are okay, ...Read more

Is herpes spread ne other way than sex? A person in my house recently found out she has herpes. Can it spread only by sex? Is it ok to share toilets razors and/or towels?

Is herpes spread ne other way than sex? A person in my house recently found out she has herpes.  Can it spread only by sex?  Is it ok to share toilets razors and/or towels?

Genital : Genital and oral (mouth) herpes is spread by direct contact with the herpes virus (through intimate contact). In addition oral herpes can be spread by sharing the same glass. Cigarette, lipstick, etc. Spreading of the virus through inanimate objects such as towels or bed sheets is highly unlikely since the herpes virus can not live outside the body for very long. As far as razors are concerned, you should never share a razor with anyone due to the fact that blood may be present which presents many other risks. Take care. ...Read more

Can you catch aids from toilet paper in public toilets or by touching a surface other than someone's genitals?

Can you catch aids from toilet paper in public toilets or by touching a surface other than someone's genitals?

Unlikely: To my knowledge, there has not been a case contracting HIV this way. Hiv virus cannot survive for long outside of the body. It is transmitted by getting contaminated blood through transfusion, dirty needles, or through bodily fluid during sexual intercourse. Even saliva is reported to not carry enough viruses to transmit the disease. It should be safe to use public restroom. ...Read more

Is it possible to transmit HSV2 other than through sexual contact like not washing hands after urinating, sharing towels or razors?

Is it possible to transmit HSV2 other than through sexual contact like not washing hands after urinating, sharing towels or razors?

No.: Herpes can only be acquired through sexual activity -& these days that can be through various routes. Inanimate objects cannot 'harbor' the virus -so towels, razors etc cannot infect someone later on since the virus dies after leaving the body of an infected person. So it has to be contact to contact. Other diseases though like MRSA can come from infected razors, so it's always good to be hygienic ...Read more
