In cases of severe to make a lifelong disability. And some may even be fatal. At present, the incidence of polio has dropped dramatically. As a result of the polio vaccine coverage is high
due to the polio virus. Held in the family And the Picornaviridae There are 3 Serotype Enterovirus Type 1, 2 and 3, each of which may have been found to cause paralysis type 1 causes paralysis and the outbreak, more often than attenuated other sites. Once infected, it is a kind of permanent immunity occurs only on sites that attenuated. No antibodies to other sites, so attenuated by theory, could infect up to 3 times
the epidemiology of this infection in the intestines of people. No other disease reservoir The virus proliferation in the intestines of people without immunity and within 1-2 months, when the digestive tract to the outside. Can not multiply Infection is located outside the body and in the environment did not last long. Especially in the tropics. Old Half-life of poliovirus (half life) about 48 hours of contact is important. Infection is excreted in the feces into one another through the mouth (fecal-oral route) by contaminated hands, passing from one person to another (person to person) and enter the body when picked. the food into the mouth In areas with personal hygiene. And sanitation Not up to standard to meet polio is common in children under 5 years and is contacted by fecal-oral route in industrialized countries. The level of personal hygiene, sanitation and good contact is mostly an oral-oral route by the bacteria multiply in the throat. Or upper gastrointestinal (oropharynx) were driven out with pharyngeal secretion out of the mouth of contamination for the handling of food into the mouth of another. Polio is a contagious disease that is very simple. The vaccine's PVC covers more than 80 percent in the incidence of this disease has resulted in greatly reduced. And developed countries, many of which have reported polio
patients with onset of paralysis between 1-2 weeks, but may last up to 5 days or as short as 3-4 days.
