Smallpox is an acute, infectious and sometimes fatal disease caused by the variola virus and noticeable by fever and a distinctive progressive skin rash. The last naturally happening case of smallpox occurred in Somalia in 1977 and the World Health Organization has measured the disease eradicated since 1979. The previous occurrence of the disease in the United States was in 1949. However, given the threat of bioterrorism since September 11, 2001, it is measured a disease that could be intentionally released during a bioterrorist. Smallpox spreads from make contact with infected persons. Generally, direct and fairly extended face to face contact is necessary to spread smallpox from one person to another.
Smallpox also can be extend through direct contact with infected bodily fluids or impure objects such as bedding or clothing. The indications of smallpox begin with high fever, head and body aches, and sometimes vomiting. A rash follows that spreads and progresses to raised bumps and pus filled wound that crust, scab and fall off after about three weeks, leaving a pitted scar. After exposure, it take between seven and 17 days for symptoms of smallpox to show (average incubation time is 12 to 14 days). During this time, the dirty person feels fine and is not contagious.
After exposure, it takes between seven and 17 days for symptoms of smallpox to appear (average incubation time is 12 to 14 days). During this time, the infected person feels fine and is not contagious. Vaccine administered up to four days after publicity to the virus, and before the rash appears, provides defensive immunity and can prevent infection or lessen the severity of the disease. No effective treatment, other than the management of symptoms, is at present available. A number of compounds are under study as chemotherapeutic agents. If the virus was to present itself again it could be prohibited by vaccination of close contacts of those who have been infected.
