Well, if you want to prevent diseases from wearing other people's clothing, then you should definitely make sure that the clothing is very clean, and I know you don't want to here it, but the most efficient way to eliminate spread of disease in this manner is just to not wear the other person's clothing.
AIDS (Acquired Immune Deficiency Syndrome) is not transmitted. HIV (Human Immunodeficiency Virus) is the virus that causes someone to develop AIDS. HIV is transmitted by contact with body fluids; blood, semen, vaginal fluid and breast milk. Many diseases can be transmitted by the same body fluids including a variety of STD's and bloodborne illnesses like hepatitis.
You are highly likely to get pregnant (or get someone pregnant). And/or get infected with one or more of the many highly contagious, sexually transmitted diseases. Having unprotected sex is like playing Russian Roulette.
HIV is not transmitted through clothing. Even if someone were to wear the underclothing of an HIV infected individual, the virus is not transmitted in this fashion.
infectious diseases (those with bacterial or virus, or prion) you can also "catch" chemical based diseases such as contamination burns if you come into contact with someone with the chemicals on them.
No. Some diseases are not infectious. Even with ones that are, a person is not definitely going to get it by being in contact. Different diseases have more or less chances of infecting someone else and there are various ways a disease can be transmitted.
The reason that cancer is an example of a non-communicable disease is that it can not be transmitted person to person. A cold is communicable because you can get a cold from someone else.
Genetic diseases are not transmitted by contact with someone else who has the disease. Diseases of lifestyle choice are not contracted by contact with any infectious agent either (i.e. diabetes caused by being overweight, sedentary, and improper diet).
No. Lupus is an autoimmune disorder, wherein your body produces antibodies against itself. Lupus is not an infection, and it cannot be transmitted from an affected person to another.
can u test postive for meth if you have been around someone smoking or making the drug
Yes, if you share a needle with someone who has a sexually transmitted Disease/Infection then you too can contract said disease/infection. Disease/infection needs transfer of bodily fluids to spread.
No, sweat itself is not contagious. However, if someone with a contagious condition like a virus or bacterial infection sweats on you, there is a possibility that the infection could be transmitted through contact with their sweat.
Depends on what you do. You can get sexually transmitted diseases if you go down on someone who has one if your tongue is not completely healed. You can get STDs whether your have a tongue piercing or not. If you go to a shoddy piercer with dirty tools/environment, you could get Hepatitis or even HIV/AIDS. Neither of those are problematic if you go to a certified, reputable piercer.
