Smallpox
Diagnosis
Smallpox can be diagnosed by a patient's clinical signs and symptoms. When smallpox was common, an experienced clinician could make the diagnosis simply by looking at the rash and examining the patient. any case that occurs now will likely be a result of bio terrorism or biological warfare.
How is it transmitted?
Smallpox is highly contagious. In most cases, people get smallpox by inhaling droplets of saliva, which are full of virus, during face-to-face contact with an infected person. they have no symptoms for 10 to 12 days. Contaminated clothing or bed linens also can spread the virus. Those caring for people with smallpox need to use special safety measures to ensure that all bedding and clothing from the infected person are cleaned appropriately with bleach and hot water.
Relative frequency of smallpox
There is no relative frequency of smallpox. The last case of smallpox in the United States was in 1949. The last case in the world was in Somalia in 1977. Worldwide vaccine campaigns have wiped out smallpox everywhere. Since the disease no longer occurs naturally anywhere in the world, smallpox vaccination for the general public was stopped because it was no longer necessary. Today, smallpox virus is kept in two approved laboratories in the USA and Russia.
Disease Course
Once smallpox enters the body ,there was a one- to two-week incubation period during which the person showed no signs of infection.Illness first becomes apparent with a sudden high fever of 101 to 105 °F.Two to five days later these flu-like symptoms go away . However, they were followed by the appearance of lesions in the mouth and by a rash on the skin that was heaviest on the face and lower part of the limbs.
possible complications
Most people who get smallpox survive. However, there are a few rare varieties of smallpox that are almost always fatal. These more severe forms of smallpox most commonly affect pregnant women and people with impaired immune systems.

People who recover from smallpox usually have severe scars, especially on the face, arms and legs. In some cases, smallpox may cause blindness.

Description
Smallpox is a highly contagious, infectious, and deadly disease that is cause by a virus which is usually spread through the air and which enters the body through the nose. "Classic" smallpox is often referred to as "Variola major". Symptoms of the disease include of bumps and rashes filled with a pus-like substance that appear all over the body.
Humans are the only natural hosts of variola (the virus that causes smallpox). Therefore, smallpox transmission does not occur through animals or insects.
