How Polio Transmited

Poliomyelitis caused by polio virus. One in 200 infections develop into paralysis. A total of 5-10 percent of patients paralyzed, died when his breathing muscles become paralyzed. Mostly affects children under the age of three years (more than 50 percent of cases), but can also affect adults. Prevention by vaccination at regular intervals, ideally in childhood.

Viruses enter through the mouth and nose and then multiply in the throat and digestive tract or gut. Furthermore, absorbed and spread through the blood vessels and lymph vessels.
Direct transmission of the virus occurs in several ways, namely:

a. faecal-oral route (from feces to mouth)
 Through drink or food contaminated polio virus from stool of patients and into the mouth of healthy individuals.
b. Oral-oral (from mouth to mouth)
transmission through saliva splashes into the mouth of the patient that other healthy people. Actually, the high temperature conditions can quickly turn off the virus. Conversely, in a frozen state or a low temperature it can survive the virus for years.
Virus resistance in soil and water depends on temperature and humidity of other microbes. The virus can survive longer in the waste water and surface water, even up to miles and miles from the source of infection. Polio virus is highly resistant to alcohol and lisol, but sensitive to formaldehyde and chlorine solution. High temperatures quickly kill viruses, but in a frozen state can last for years. Virus resistance in soil and water depends on temperature and humidity of other microbes. The virus can survive for long in the waste water and surface water, even up to miles and miles from the source of infection. Although the infection is mainly due to environmental contamination by the polio virus from patients with infectious, the virus that lives in a limited environment. One of the intermediate host or organism that can be demonstrated to date is a human.
