One of the most- worst childhood memories, is when you were as a child and you were infected by Smallpox and weren’t able to play with your friends until you get better.

Smallpox is an infectious disease that affects humans since ancient times. Infection is caused by infection with the smallpox virus. Smallpox symptoms are known to be severe, to cause malformations, and sometimes to be fatal. By 1980 smallpox had been eradicated worldwide by a major smallpox vaccination campaign. was not separated from smallpox until the late 19th century.

However, the side effects of the vaccine remain a source of fear because of its side effects on the recipient's health.

Smallpox infection transmission methods:

• Direct contact with people with the smallpox virus for long periods of time and exposure to fluids from the body, such as sneezing spray and mucus, or by breathing polluted air from the person’s lungs during the exhalation process.

Indirectly contacting an infected person, which is so rare that an airborne virus can spread through ventilation ducts to infect others in rooms and other floors of buildings.

• The use of contaminated tools such as contact with contaminated clothing or bedding is less common.


The incubation period for the smallpox virus lasts from 7 to 17 days, and the first symptoms of smallpox usually appear 10 to 14 days after infection. During this period, the patient does not feel any symptoms and cannot transmit the infection either.

After the end of the incubation period, the symptoms begin to appear suddenly and are similar to the symptoms of influenza and include:

• Fever

• General discomfort

• Headache

• Extreme fatigue

• Severe back pain

• Vomiting

After a few days, flat red spots begin to appear on the face, hands and forearms, and then on the trunk later. Within a day or two, many of these lesions turn into small blisters filled with transparent liquid, and then turn into pus. The scabs (scabs) begin to develop after eight to nine days, then fall off at the end, leaving deep scars.

Lesions also develop in the mucous membranes of the nose and mouth and quickly turn into ulcers.

Complications of smallpox

Most cases of smallpox do not result in death. However, some rare types of smallpox may be fatal. These more severe cases mainly affect pregnant women and people with weakened immune systems.

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

Smallpox prevention methods

In the event of an outbreak, smallpox patients should be kept in isolation and controlling the spread of the virus. And start giving vaccines to people who have been in contact with infected people. Taking care that the time they receive the vaccine does not exceed 4 days to reduce the severity of infection and symptoms of the disease.

If you are vaccinated as a child, your immunity or partial immunity may last for up to 10 years and up to 20 years after the re-vaccination. If the virus spreads, the vaccination of people who have been vaccinated as children is likely to be re-vaccinated in the event of direct contact with someone who has the virus.
