How can you keep smallpox from spreading to other people?

The smallpox vaccine is the only way to prevent smallpox. The vaccine is made from a virus called vaccinia, which is another pox-type virus related to smallpox. The vaccine helps the body develop immunity to smallpox. It was successfully used to eradicate smallpox from the human population.

How can you prevent smallpox from spreading?

One of the best ways to prevent smallpox is through vaccination. Vaccine given to individuals before exposure to smallpox can completely protect them. Vaccination within 3 days after exposure prevents or greatly lessens the severity of smallpox in most people.

How does smallpox spread from one person to another?

Smallpox spreads from contact with infected persons. Generally, direct and fairly prolonged face-to-face contact is required to spread smallpox from one person to another. Smallpox also can be spread through direct contact with infected bodily fluids or contaminated objects such as bedding or clothing.

What precautions are used for smallpox?

National infection control guidelines prescribe specific precautions to be taken when treating patients with known or suspected smallpox. These precautions include "Standard", "Droplet", "Airborne", and "Contact" Precautions, under certain circumstances. Patient isolation and similar precautions may also be necessary.

Can smallpox be transmitted through blankets?

The virus can spread through these materials or through the objects contaminated by them, such as bedding or clothing. People who cared for smallpox patients and washed their bedding or clothing had to wear gloves and take care to not get infected.

Do masks prevent smallpox?

The extent of reduction in the incidence of smallpox with use of this agent is uncertain. It is useless for treatment of clinical smallpox. N-100 respirators (face masks) worn by uninfected members of the public may prevent transmission of the virus.

How easily does smallpox spread?

How contagious is smallpox? Smallpox is contagious, but it's spread less easily than illnesses like influenza or measles. Generally, it takes prolonged, face-to-face contact - of the kind that takes place in a household setting - to spread the disease from one person to another.

How is smallpox spread from host to host?

Human-to-human transmission of variola virus occurs by inhalation of large, virus-containing airborne droplets of saliva from an infected person. Infectious virus particles are released from the sloughing off of oropharyngeal lesions.

Can a vaccinated person spread smallpox?

Is it possible for people to get smallpox from the vaccination? No. The smallpox vaccine does not contain smallpox virus and cannot spread or cause smallpox. However, the vaccine does contain another virus called vaccinia which is live in the vaccine.

When is smallpox most contagious?

It has an incubation period of between 7 and 17 days after exposure and only becomes infectious once the fever develops. A distinctive rash appears two to three days later. The most infectious period is during the first week of illness, although a person with smallpox is still infectious until the last scabs fall off.

Is smallpox airborne or droplet precautions?

Smallpox is spread through prolonged face-to-face contact via droplets expelled from the patient's nose and mouth, usually by coughing. Smallpox may also be transmitted through contact with materials from smallpox pustules or scabs.

What PPE is needed for smallpox?

Cover the patient's nose and mouth with a surgical mask or N95 respirator. Use only personnel who have been vaccinated against smallpox OR vaccinate personnel within 72 hours of their first exposure to the patient (preferably within 24 hours).

How can poxvirus be prevented?

Avoid contact with animals that could harbor the virus (including animals that are sick or that have been found dead in areas where monkeypox occurs). Avoid contact with any materials, such as bedding, that has been in contact with a sick animal. Isolate infected patients from others who could be at risk for infection.

How long does smallpox virus live on surfaces?

historical books written about smallpox virus and the vaccine virus, vaccinia virus, suggests that these viruses could remain viable at room temperature or its equivalent for 2-3 weeks only outside of infected individuals.

How long does smallpox last on fabric?

However, if cotton can become contaminated with smallpox scabs in temperate climates (20°-25°C) or is already contaminated when imported at this temperature, the experiments indicate that a few particles of virus may survive for as long as 18 months.

What animal does smallpox come from?

Smallpox is an acute, contagious disease caused by the variola virus, a member of the genus Orthopoxvirus, in the Poxviridae family (see the image below). Virologists have speculated that it evolved from an African rodent poxvirus 10 millennia ago.
