No. Malaria is not spread from person to person like a cold or the flu, and it cannot be sexually transmitted. You cannot get malaria from casual contact with malaria-infected people, such as sitting next to someone who has malaria.

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.

Morgellons Disease is also referred to as the 'Fiber Disease' and is, as yet, unrecognized by the medical community. Thousands who have registered report remarkably similar symptoms, generally involving lesions and fibers developing in the skin.

Hansen's disease is one of the least contagious of all communicable diseases. Only 5% of the world's population are susceptible to the disease. It is very difficult to contract.

According to an article in the September 1997 issue of the Journal of the American Dental Association, bacteria causing periodontal disease may be passed though saliva. The American Academy of Periodontology recommends that if one family member has periodontal disease, then all family members should see a dental professional for a periodontal disease screening.

Lyme disease is not contagious and cannot be spread from person to person. But certain precautions should be taken to prevent spread of the illness through ways such as blood transfusions. People with active Lyme disease should not donate blood, because the bacteria that cause the illness can be transmitted this way. People who were previously treated for Lyme disease may be able to donate blood, but they should check with the blood bank first.

Feline Infectious Peritonitis is a reaction to infection with the feline coronavirus. Most cats who become infected with the feline enteric coronavirus (often simply called "feline coronavirus") essentially get the flu and never develop anything that can in any way be described as serious. Some cats, however, react with this devastating syndrome.

Hansen’s disease is one of the least contagious of all communicable diseases. Only 5% of the world’s population are susceptible to the disease. It is very difficult to contract.

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.

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.

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).
