Contact-household transmission characteristic of intestinal infections. Salmonella, E. coli, dysentery fall on your hands, and with them - food, toys or dishes. That is, infection occurs via an intermediate object, though it may be by direct contact, for example through a handshake. Thorough hand-washing and children's toys, isolation of cases and personal utensils - basic safety precautions. Intestinal infections are transmitted by the same nutritional - inadequate heat treatment or washing products, eating spoiled food leads to disease.
Helminthiasis is also considered a "disease of dirty hands", infection occurs via an intermediate object or through the alimentary, that is, by eating contaminated food. That is, after cutting meat bad enough to wash your hands and everything that touches the hostess, will be contaminated by helminth eggs. In this case, has a value of the degree of purity of meat or fish. Infection with helminths can occur through contact with animals.
Infectious dermatitis, such as Candida and strep, are transmitted by direct contact and through contaminated objects. Infection occurs at lightning speed and often outbreaks of such infections are observed in institutions where not observed epidemiological regime.
By direct contact or through contaminated objects are transmitted fungal and parasitic diseases of the skin. If the treatment of scabies rarely goes more than two weeks, and lice modern drugs cope for a couple of days, the treatment of fungal diseases may be delayed - in some cases to achieve a full recovery and fails. There is a risk of infection from sick animals, as, for example, the radiant fungus infection occurs through contact with infected grain and flour.
Venereal disease is rarely transmitted sexually, since the pathogen outside the host is killed quickly enough. Contact-household way of infection with venereal diseases is typical for families and groups of people living together. This usually occurs through washcloths, toothbrushes. At risk children, the probability of infection in adults is available only for serious diseases of the immune system.
Most dangerous infections are transmitted including contact-household way. But today, quarantine measures helped to defeat them: flashes are extremely rare and are quickly blocked. However, tuberculosis, and these are transferred by direct contact and through contaminated objects, not included in the list of especially dangerous infections. TB treatment is long, often a full recovery is impossible. Handrails in buses, Elevator buttons - all of which can be dangerous. Should be carefully wash their hands to protect themselves from TB infection.
We are surrounded by many microorganisms and parasites, many of which can be dangerous to humans. To cause disease, microorganisms need to get in the entrance gate to the minimum required for infection number. Washing hands with soap and water, adherence to hygiene rules to reduce the risk of infection to a minimum. If it is not possible to wash hands, use antiseptic wipes and a special fluid.
