Infectious diseases


Smallpox (from the Latin Variola vera) is a highly contagious viral disease, which is characterized by profuse rash, often leaves scars. There are two types of smallpox: if the bubbles with clear or purulent contents have a yellowish color, this type of smallpox is relatively not dangerous. However, if smallpox bubbles are blue-black or bruises appear, this type of small-pox is a threat to life. Earlier during major epidemics of smallpox a lot of people died.


  • Excessive fever.
  • Malaise.
  • Fatigue.
  • Dizziness.
  • Drowsiness.
  • Back pain and painful skin rash.
  • Pale bubbles with clear content, bleeding blisters.


Smallpox is caused by virus, which is highly resistant to changes in temperature. Mode of transmission – airborne, but also can be transmitted by close contact with the patient.


Smallpox patients are urgently hospitalized and isolated from the outside, as the disease spreads very quickly. Smallpox is a viral infection, so antibiotics are completely ineffective. Usually doctors treat only the symptoms of various diseases, such as fever, back pain, or painful skin rash. Antipyretic and analgesic medications are given to patients.

If a person has a sudden onset of fever, pain in the limbs, and there were red spots that resemble the elements of a rash, you should seek medical advice immediately. Today, the probability of smallpox really small, and it’s probably some other disease with similar characteristic symptoms.

The doctor examines the patient very carefully, examines the elements of rash and hold laboratory blood, and possibly also the contents of the bubbles.

Course of the disease

At the end of 1-2 weeks after infection, excessive fever, chills, painful back pain occur in a patient. Other symptoms – fatigue, dizziness and stiff neck. A few days later the body temperature drops, and there are characteristic rash (first on the face, and then throughout the body). Elements rash – pale bubbles with clear content, which gradually turns to yellow pustules (blisters with viscous purulent content). A person’s body temperature raises again, somnolence, dizziness, hallucinations begin. A patient has greatly hurt places, which is affected by a rash. After several days pustules begin to dry out, the fever persists, the human condition is improving.

If a person suffers from a severe form of the disease, he may die.

The most effective way is vaccination, which in 1796 were invented by E. Jenner. Through the efforts of doctors and grafting against smallpox infection was eliminated. The last case of smallpox was in Somalia in 1977.
