November 3, Reviewed by: January 01, Introduction to smallpox: Smallpox long reigned as the king of dreaded contagious diseases. It killed more people than any other virus in recorded history — about million people in the 20th century alone. Many had never even heard of it.
Smallpox is one of the classic childhood viral illnesses. Even before that, smallpox left physical evidence — it has been found in ancient Egyptian mummies. The disease later spread as part of the great Islamic expansion across North Africa and into Spain.
The ill-fated travel of the Crusades then brought it to the rest of Europe where for many generations it caused about 10 percent of all deaths every year. European explorers then brought it to the American colonies, where epidemics were devastating to colonists — but especially to Native Americans.
Virus-contaminated blankets may have been given to natives as intentional acts of biological warfare. Later, George Washington believed that British troops intentionally infected colonial forces with it.
Eventually, almost everyone on earth got infected. This airborne disease was so contagious that it became a standard feature of life on our planet.
Most people recovered, but the overall mortality rate when infected was 1 to 30 percent — and even higher during some epidemics. Today we are living in a New World, not unlike the one discovered by the European explorers.
We live in a world with little immunity to smallpox, and where people might be inhumane enough to intentionally spread it. Inthe World Health Organization WHO began an intense campaign to eradicate smallpox from the planet through quarantine and vaccination.
People all over the world lined up to get the shot on their upper left arm. The last case of wild smallpox occurred in The last reported case of non-wild infection occurred in when two people contracted the disease after exposure to the virus in a lab.
What are the symptoms? People with the illness got sick suddenly, with a high feverheadacheand marked fatigue. Nausea, vomitingabdominal pain, back pain, and muscle pains were also common. The pox usually lasted 10 or 12 days, with the fever often returning. Red Book 1Is smallpox contagious?
Symptoms usually develop 7 to 17 days after exposure. The illness then usually lasts about 2 weeks. How is smallpox diagnosed? Laboratory diagnosis is available.
How is smallpox treated? In the past, the goal of smallpox treatment was to support people until the disease had past.
If smallpox occurs again, other treatments may be tried. Also, giving the smallpox vaccination within days after exposure to smallpox may prevent illness, or at least make it less severe.Treatment If athe smallpox vaccine is given within days after a person is exposed to the disease, it may prevent illness or make the illness less severe.
Once symptoms have started, treatment is limited. A person with smallpox goes through several stages as the disease progresses. Each stage has its own signs and symptoms. The incubation period is the length of time the virus is in a person’s body before they look or feel sick. During this period, a person usually has no symptoms and may feel fine.
In the past, the goal of smallpox treatment was to support people until the disease had past. If smallpox occurs again, other treatments may be tried.
Also, giving the smallpox vaccination within days after exposure to smallpox may prevent illness, or at least make it less severe. There is no proven treatment for smallpox disease, but some antiviral drugs may help treat it or prevent it from getting worse.
There also is a vaccine to protect people from smallpox. If there were a smallpox outbreak, health officials would use the smallpox vaccine to control it.
The first symptoms of smallpox usually appear 10 to 14 days after you're infected. During the incubation period of seven to 17 days, you look and feel healthy and can't infect others. Following the incubation period, a sudden onset of flu-like signs and symptoms occurs.
Signs and Symptoms The signs and symptoms of smallpox gradually emerge and may be difficult to distinguish from other diseases in the early phases. After exposure, a person usually has no symptoms for up to 17 days; this is the time when it is most important to get vaccinated to prevent disease.
