There are three main causes of infectious diseases: bacteria, viruses, rickettsia. In addition, there are problems associated with large parasites — such as parasitic worms, scabies (mites) and tropical bovine gadfly larvae, and jigger (sand fleas). For diseases caused by bacteria include dysentery, cholera, tuberculosis and diphtheria. Viruses are the cause of what we call the common cold (acute viral respiratory illness — SARS), Influenza, measles, and polio. Rickettsia — microorganisms that are neither bacteria nor viruses — cause disease typhoid fever tsutsugamushi or akamushi (Jungle Fever), Rocky Mountain spotted fever. The most common viral diseases that are well known to all from childhood, are treated just good care. They become infected from other people. If they are not in your group (or those people with whom you come in contact), they, like the others transmitted from person to person, including sexual, disease, have little chance to appear in your group. Some human parasites such as itch mite that causes scabies can not live long without contact with the human body, so they can also be a problem only if you have already attended the representatives of your group who are saved.
This type of vitamin deficiency that occurs due to a lack of vitamin C, was once the scourge of sailors on long voyages. If possible the consumption of fresh fruits and vegetables, the risk of the disease is reduced to zero. Good news for the fallen in the desert or the polar zone is that they will die of thirst or starvation long before the serious aggravation of the problem. Symptoms: bleeding gums, teeth swinging, bruising at the slightest shock or respiratory failure.
Lesson only hunting and fishing may exacerbate the problem, especially in the polar regions, if you run out of pills vitamins. Always try to eat a balanced diet to avoid exactly how scurvy, and other types of beriberi.
Peddlers of diseases that are most likely infected, especially in the tropics, are contained in the water, insects and animal foods. Since the symptoms of most tropical diseases entering the emergency are less familiar, the most common will be discussed in more detail so that you can identify them. When there is no medication, the treatment of the disease will be largely limited to treating symptoms and providing maximum patient comfort. You can cook some drugs from natural resources. However, prevention is better than cure. In the ways of preventing the disease should include all appropriate vaccinations before sending a journey (especially in the tropics), and then give the most serious consideration to the following preventive measures. — Clean drinking water. — Washing hands while cooking and eating. — Washing and cleaning fruit from the skin. — Sterilization of kitchen and table utensils. — Wearing a means of preventing insect bites. — Washing clothes and maintaining it in the smoke in case of lice. — Washing of the body (for washing and bathing or swimming do not swallow water, which can be dangerous to health.) — Disposal of excreta. — Protect food and drink from flies and vermin.
Care / insulation
If, however, there was an infectious disease, it is important to prevent its spread. Contact sick with other members of the group should be kept to a minimum. All utensils used by patients, must be boiled. Cuts and abrasions should be tightly closed, so that they were not open to infection. After nursing his hands should be washed thoroughly. When coughing or sneezing, avoid spraying the patient mucus, which may contain germs. While disposing excreta patient Care is taken to deal with this assistant is not infected, and they were buried so that they could not disturb people or animals.
