Small pox virus name

What Is Smallpox? Today, scientists keep only a small amount of the virus alive under tightly controlled conditions in the U.S. and Russia for medical research. Routine smallpox Smallpox Symptoms Smallpox gets its name from its most common sign of the disease: small Other symptoms include: • • • Body aches • Intense • Some • • • A • The rash starts with flat red sores that become raised bumps a few days later. • The bumps turn into fluid-filled blisters. • The • They crust over, usually in the second week of smallpox. • Scabs form over the blisters and then fall off, usually in the third week of the disease. They can cause permanent scars. • Blindness can happen when blisters form near the Smallpox Causes The variola virus causes it. There are two forms of the virus. The more dangerous form, variola major, led to smallpox disease that killed about 30% of people who were infected. Variola minor caused a less deadly type that killed about 1% of those who got it. Two forms of smallpox were more deadly than the common strain: Hemorrhagic and malignant. Hemorrhagic smallpox tended to affect adults, including Malignant smallpox tended to affect children, not adults. Instead of raised blisters, people developed flat lesions that merged on the How Smallpox Is Spread The disease is highly contagious. You could get it: • By • By handling the clothes or sheets of an infected person or coming into contact with their body fluids. • Very rarely, smallpox has spread among people in small...

Smallpox was a serious illness caused by the variola virus. It caused a severe rash that often left disfiguring scars. About 1 in 3 people who got smallpox died. Smallpox has been eradicated since 1980. There haven’t been any cases since 1978. Smallpox was the first disease for which there was a vaccine. Overview Smallpox caused a hard, blistering rash over most of your body that left disfiguring scars. What is smallpox? Smallpox was a serious illness that killed hundreds of millions before its eradication. It caused a hard, blistering rash that often led to disfiguring Beginning in the 1960s, the World Health Organization (WHO) led efforts to stop the spread of smallpox worldwide. By Does smallpox still exist? Smallpox no longer exists in humans or spreads naturally. There haven’t been any cases of smallpox in the last 45 years. Two laboratories (one in the U.S. and one in Russia) have stocks of the virus that causes smallpox for research purposes only. How did we eradicate smallpox? Some factors that may have contributed to successfully eradicating smallpox include: • Only humans get smallpox. It doesn’t spread through animals or insects. This means fewer ways to get infected. • It was easy to identify. Everyone who had smallpox had symptoms, including a characteristic rash. No one carried smallpox without knowing it (no asymptomatic carriers). • It spread relatively slowly. Smallpox usually wasn’t contagious until an infected person was too sick to be around many other ...

• Ordinary smallpox is the most frequent, making up 85% of cases. • Modified variola major is mild and occurs in vaccinated persons. There are fewer lesions, and they heal faster. • Flat or malignant-type smallpox causes a rash that shows up slowly, merges, and remains flat and soft or “velvety” to the touch. It’s rare and more deadly. • Hemorrhagic smallpox causes reddened skin, burst blood vessels, and bleeding from the gums and sores. One of the first ways humans tried to control smallpox infection was by variolation. This involved taking scabs from people with smallpox and scraping them into an open cut on the skin of people who didn’t have smallpox or having them inhale this scab material through their noses. These people would get milder smallpox, and their immunity would protect them from severe smallpox. • Cowpox: This virus can be contracted by both cows and humans. Humans can acquire it from cattle, but it is not transmitted from human to human. • Vaccinia: This virus can also be contracted by cattle. It is the live virus used in the smallpox vaccine. • Mpox (formerly known as monkeypox): This virus can spread from human to human through direct contact with the lesions and scabs. It caused a worldwide outbreak in 2022. • Camelpox: This virus can be contracted by camels and can also cross over to humans. • Buffalopox: This virus is closely related to vaccinia. Outbreaks are seen in India in cattle, buffaloes, and humans. When the sores in the mouth break down, the...
