Can you get HIV or hep c from sharing a toothbrush?

Can you get HIV or hep c from sharing a toothbrush?

Not likely: It can possibly happen if the person has a high viral load in the blood and have gums bleed all over the tooth brush and you use it immediately after they do. If you think that you may have been exposed then get tested.

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 a person is infected with HIV is it possible to get infected if I rinsed his toothbrush in the sink and some of the water splashes into my eyes?

If a person is infected with HIV is it possible to get infected if I rinsed his toothbrush in the sink and some of the water splashes into my eyes?

Extremely unlikely: In some persons living with hiv, the virus has been detected in saliva, but in extremely low quantities. Contact with saliva alone has never been shown to result in transmission of hiv, and there is no documented case of transmission from an hiv-infected person spitting on another person. If tainted with blood it increases the chances but extremely unlikely. If concerned, get tested.

My daughter was chewing on my mothers toothbrush. I don't think my mother does, but can my daughter get HIV or hep c that way?

My daughter was chewing on my mothers toothbrush. I don't think my mother does, but can my daughter get HIV or hep c that way?

Very unlikely: Even if her grandmother has HIV or hepatitis c, it is very unlikely to get such infections simply by chewing the toothbrush used by her.

My daughter was chewing my moms toothbrush. I don't think my mom has anything, but can she get hiv, hepatitis c, or STDs from chewing on it? I'm worry

Should be OK: Theoretically yes, but I have not read any research or case histories of it happening. I recommend a poliite conversation with your mother about her health to ease your mind.

Can HIV transmit through toothbrush?

Can HIV transmit through toothbrush?

Very unlikely!!: Hiv travels through blood transmission. Saliva has low or no potential to transmit hiv. If two people have bleeding gums and one has hiv, and both share the same toothbrush... Yes it is possible. But if neither has gum issues, the probability of transmission is about the same as sharing eating utensils. Get an HIV test buy another toothbrush and stop worrying!

Are there many cases of HIV or hepatitis C being transferred by a toothbrush? Is there any cases?

Are there many cases of HIV or hepatitis C being transferred by a toothbrush? Is there any cases?

Blood on it?: Hiv & hepatitis c are transmitted by contact with an infected persons blood. No blood = no transmission. However think of all those virus and bacteria that can be passed on shared toothbrushes & other personal care items. I certainly can't imagine sticking a toothbrush in my mouth that has someone's morning crud all over it.

Can HIV or hepatitis C be transmitted by a toothbrush easily?

Not easily: Hiv would be very very unlikely. The virus dies quickly outside the body, elements in saliva provide protection from infection, you would have to have some sort of open wound, and there would have to be large # of viruses. Same is almost true for hep c except it doesn't die quite as quickly and it takes fewer viruses to infect. I do not know of any cases that have been transmitted by a toothbru.

Can you contract HIV virus by sharing thesame toothbrush with an infected person?

Can you contract HIV virus by sharing thesame toothbrush with an infected person?

Very unlikely: Fortunately, the viability of HIV is very short lived outside of the body and is not contagious once exposed to air and surfaces that dry. There would be some minimal risk if the brush was used immediately after an infected person brushed with it by another. Virtually little to no risk if there was some significant time.

Never had sex before, worried about HIV/AIDS, tested April 2014 negative, never had sex since. Scared of toothbrush transmission.?

Never had sex before, worried about HIV/AIDS, tested April 2014 negative, never had sex since. Scared of toothbrush transmission.?

Unnecessary concern: If you really have no exposure to blood or fluid from HIV, why are you so concerned? Are you sharing toothbrush with another person? If so, why? Even then it would be nearly impossible for you to acquire HIV via a toothbrush unless it is soaked in HIV infected blood. You need to talk to a psychologist or psychiatrist re. This phobia.

I left my new toothbrush out for 30 minutes without rinsing it properly after using it. Did it get enough germs where I need a new toothbrush?

I left my new toothbrush out for 30 minutes without rinsing it properly after using it. Did it get enough germs where I need a new toothbrush?

Probably not: No matter how much you rinse your toothbrush you will always leave gems on it. If you want to really clean your toothbrush you can run it through the dishwasher or let it soak in a weak bleach solution for about 30 minutes. If you do that, make sure you rinse it well to get the bleach out.

Use both: Electric toothbrush is to brush teeth on front back and the top... Where as waterpik helps to dislodhe plaque or foid in between the teeth. Would advise flossing.

Can toothbrush bristles get harder or softer with use?

Agree and. ..: Worn toothbrushes tend to fray & tangle at the bristle ends, thus are less effective. If it looks worn, it's time for a new soft never hard bristle toothbrush.
