Yes. About 1% of the population carries MRSA on the skin – they are considered to be ‘colonized’ with MRSA and are generally asymptomatic. People who are exposed to the organism from a carrier generally do not get sick from it, or develop only mild illnesses (similar to normal staph infections). However, if a minor infection is not cared for, or if there are other factors (e.g., compromised immunity), then the infection may become more serious.

A: Ichthyosis is definitely not contagious. It is not caused by a bacteria, virus, or germs, and thus it cannot be passed from one person to another.

No, epilepsy is never contagious. You cannot catch epilepsy from someone else and nobody can catch it from you.

In many respects, yes. If you have one on your feet, it would be unwise to pick at it and it can spread to someone else if that person has the potential towards getting that virus in the same way certain people have the potential for catching a certain cold. The wart virus likes to linger around moist environments such as pools, spas, locker rooms, public showers (such as those at the gym). Wearing flip flops or crocs in these areas is always a good idea.

EMS is not a contagious disease. There should not be fears about that. Naturally, chronic diseases such as EMS may have profound effects upon close family members of the sick person and might contribute to feelings of depression, anxiety, problems with children accepting the illness, or other physical and emotional conditions in loved ones. But this occurs with any chronic illness that goes on for many years - which is what a chronic illness is, an ongoing one.

Vitiligo is NOT contagious. If it were, many more people in the world, including doctors who treat vitiligo and family members of those with vitiligo, would have the condition. There are many theories about what causes vitiligo, but many experts believe, and data supports the theory, that one must be genetically susceptible, in order to develop vitiligo.

While the exact cause of the disease is not known, what is known indicates that Parkinson's is not contagious. Parkinson's is a neurological, not a mental, disorder. In the majority of cases, it slows the body, not the mind. However, when brain cells are affected by medication, some emotional changes can be expected. Anxiety and depression are very common among people with Parkinson's and may occur due to seratonin imbalance, a side effect of certain medications.

No, it's important to note that BSE is not a contagious disease; spread occur through the ingestion of infected material, generally brain or spinal cord tissue.

Smallpox is less contagious than chickenpox or measles. The great majority of people in a large room will become infected if even only one person has measles, whereas the highest risk for smallpox is face-to face contact, i.e. within 2 meters (6.5 feet). If there is personal protective equipment (fit-tested N-95 masks, gloves, etc.) on you and the patient, the risk of airborne spread becomes very low.

Yes, definitely. But they can't jump from head to head and they can't fly. The only way they can be transmitted is by direct contact (heads touching) or indirect contact (a hat passed around which has been worn by a person with headlice).

Any body who has the virus is a carrier and can infect others. Very often the person does not know that he/she is a carrier. He/she has no symptoms of the disease and the person who infected him/her may have had no symptoms either. A person can be a carrier unknowingly for many years and may keep transmitting the infection to others if he/she does not take proper precautions. A carrier becomes symptomatic only when the virus has destroyed so much of the immune system that he/she falls ill.

Yes, some forms of bacterial meningitis are contagious. The bacteria are spread through the exchange of respiratory and throat secretions (i.e., coughing, kissing). Fortunately, none of the bacteria that cause meningitis are as contagious as things like the common cold or the flu, and they are not spread by casual contact or by simply breathing the air where a person with meningitis has been.

Lupus is not contagious and it is not cancer. You cannot "catch" lupus, or give it to another person.

The flu virus becomes contagious one day before you feel sick. The virus enters through your nose, throat, or lungs from the air. It then begins to multiply, usually causing symptoms within a day or two. Children, on the other hand, can pass the virus on for more than a week. You can contract the flu if you touch a surface that has the flu virus on it and then touch your nose or mouth.

No, asshand is a result of surgical grafting of ass skin onto the hand, and is in no way communicable to others. It is just gross.

Bad breath is not contagious. It is caused by common body bacteria breaking down proteins in the mouth for metabolism. You cannot cough on someone and give them bad breath. However, it is certainly possible to transfer bacteria to another person by kissing them. But these bacteria would need to be transferred to a receptive bad breath environment. In other words, quite possibly you already have bad breath and did not realise it.
