Close physical contact, such as sitting near someone or sleeping near someone who has HIV is not a route of transmission.
A person's bodily fluids must have contact with the infected person's bodily fluids (ex. semen, vaginal fluids or blood), in order for transmission to occur.
That is correct; you would have to touch the saliva or mucus of the infected person to catch it.
You can contact staph from your dog but it is rare when good hygiene practices are in place. Your dog can harbor the bacteria and transmit it through cut or scrap on the owners skin when they come in contact with bedding or infected skin.
It's called a direct transfer transmission. It involves contact of an infected person with a susceptible person and the physical transfer of organisms.
It appears that trichomoniasis is one of the few STDs that can be caught through other means as well. Although the protozoan dies rapidly in dry conditions, it appears that you can be infected by sharing a washcloth with an infected person, or possibly by having your genitals come into contact with someone else's infected genital discharge.
HIV is transmitted through contact with infected blood, semen, vaginal fluid or breast milk. Fluid-to-fluid exposure is required to transmit infection. Healed wounds would likely not pose an HIV transmission risk.
You can be infected with shingles through direct contact with someone inffected of the virus.
direct contact
Meningitis is primarily spread through respiratory secretions like saliva or mucus, often through close contact with an infected individual. It can also be spread through direct contact with an infected person's respiratory secretions or by touching surfaces contaminated with the bacteria or viruses that cause meningitis.
No. To become infected with HIV there must be an exchange of body fluids. Even having a HIV-infected person bleed on you isn't dangerous unless it gets into a cut or other injury.
Microorganisms have several avenues in which they can infect larger organisms. They can enter the body through any of the body's natural openings, through wounds or injection and some can even cause infections through skin contact.
No. HIV is transmitted through contact with infected body fluids (blood, semen, vaginal fluid or breast milk.)
HIV is spread through contact with infected blood, semen, vaginal fluid or breast milk. Preventing the spread of HIV requires avoiding contact with infected body fluids.
