Overview
Smallpox is a serious and often deadly viral infection that is contagious and can cause permanent scarring and disfigurement. It has affected humans for thousands of years but was eradicated worldwide by 1980 due to smallpox vaccines. Although smallpox no longer exists naturally in the world, samples of the smallpox virus are kept for research purposes, and it can be created in a lab. Smallpox can be prevented through vaccination, and there are two available vaccines: ACAM2000 and Jynneos. These vaccines can also provide protection against similar viral infections such as mpox and cowpox. Smallpox can be spread from person to person when the rash appears and until the scabs fall off.
Understanding the disease
Symptoms
The symptoms of smallpox include sudden flu-like symptoms such as fever, muscle aches, headache, severe fatigue, severe back pain, and vomiting. A few days later, flat, red spots appear on the body, which turn into small blisters filled with clear fluid, then pus, and finally scabs that fall off, leaving deep, pitted scars. Smallpox can be spread from person to person when the rash appears and until the scabs fall off. about other questions.
Development
After the incubation period, smallpox typically begins with flu-like symptoms such as fever, muscle aches, headache, severe fatigue, and severe back pain. Soon after, a rash develops with flat, red spots appearing on the body, starting in the mouth and on the tongue before spreading to the skin. The spots turn into small blisters filled with clear fluid, then pus, and eventually form scabs eight to nine days later. The scabs eventually fall off, leaving deep, pitted scars. The virus can be spread from person to person when the rash appears until the scabs fall off.
Assessment and Diagnosis
Triage
If smallpox is suspected, you should see a doctor immediately. Symptoms of smallpox include sudden flu-like symptoms such as fever, muscle aches, headache, severe fatigue, severe back pain, and vomiting, followed by the appearance of flat, red spots on the body that turn into small blisters filled with clear fluid and later with pus. The rash progresses, forming scabs, and eventually falls off, leaving deep, pitted scars. Smallpox is a serious and often deadly viral infection that can be spread from person to person when the rash appears and until the scabs fall off. If you suspect smallpox, contact your healthcare provider right away to receive appropriate diagnosis and treatment.
Diagnosis
To diagnose smallpox, a health care provider would typically use the following methods:
- PCR testing: Polymerase chain reaction (PCR) testing is the most commonly used method to diagnose smallpox. This test detects the presence of the virus's genetic material in a patient's sample, usually obtained through a nose or throat swab.
- Tissue samples: If PCR testing is negative but smallpox is still suspected, a health care provider may take a sample of the lesions or rash and test it in special labs at the Centers for Disease Control and Prevention (CDC) to confirm the diagnosis. It's important to note that due to the eradication of smallpox in 1980, the disease is now rare, and there are no known cases of smallpox in recent times. However, if an outbreak were to occur, health care providers would follow these diagnostic procedures to identify and contain the virus.
Management and Treatment
Complications
Potential complications of smallpox include severe scarring, especially on the face, arms, and legs, as well as vision loss (blindness). More severe forms of smallpox can be deadly, especially for pregnant women and children.
Prevention
Smallpox can be prevented through vaccination. Two vaccines are available: ACAM2000 and Jynneos. Both vaccines offer protection against smallpox, as well as other similar viral infections such as mpox (monkeypox) and cowpox. Vaccination should be given before or one week after exposure to the virus. However, it's important to note that smallpox vaccines carry some risks, especially the ACAM2000 vaccine, which can cause serious side effects like infections in the heart or brain. The risks of the vaccine may outweigh the benefits for most people, especially when there is no smallpox outbreak.
