Smallpox is a potentially deadly infectious disease, which has been caused by a poxvirus that is transmitted from person to person that causes high fever, characteristic rash, and may kill about one-third of those infected. Smallpox is the only disease that has been completely wiped out throughout the world. Read out the following lines to know more about the small pox and it symptoms and its remedy.
How Smallpox spread?
Smallpox spreads from one person to another from saliva droplets. It may also be spread from bed sheets and clothing. It is most contagious during the first week of the infection. It may continue to be contagious until the scabs from the rash fall off. The virus can stay alive between 6 and 24 hours. People were once vaccinated against this disease. However, the disease has been mostly wiped out from all over the world.
Symptoms of Smallpox
The following are the symptoms of smallpox that one has to keep in mind. The symptoms include fever, overall discomfort, head ache, severe fatigue, severe back pain and something vomiting and other basic symptoms for virus. A few days later, flat, red spots appear first on your face, hands and forearms, and later on your trunk. Within a day or two, many of these lesions turn into small blisters filled with clear fluid, which then turns into pus. Scabs begin to form eight to nine days later and eventually fall off, leaving deep, pitted scars.
Causes of Smallpox
Smallpox is caused by infection with the variola virus. The virus can be transmitted either directly from person to person, indirectly from an infected person, it can also spread through contaminated items, and also the virus spread through as a terrorist weapon as well. If you think you may have been exposed to smallpox, contact your health care provider immediately. Contact with the virus is very unlikely unless you have worked with the virus in a lab or you have been exposed through bioterrorism.
Treatment for Smallpox
The smallpox vaccine may prevent illness or lessen symptoms if it is given within 1 – 4 days after a person is exposed to the disease. Once symptoms have started, treatment is limited. There is no specific drug for treating smallpox. Antibiotics may be given for infections that occur in people who have smallpox. Taking antibodies against a disease similar to smallpox, which is the vaccinia immune globulin, may help shorten the duration of the disease. People who have been diagnosed with smallpox and people they have been in close contact with need to be isolated right away. They will need to receive the vaccine and be watched closely. A vaccine can prevent smallpox, but the risk of the vaccine’s side effects is too high to justify routine vaccination for people at low risk of exposure to the smallpox virus.
