<h3>What is smallpox?</h3>
Variola major or Variola minor are the two virus strains that cause the contagious sickness known as smallpox. The variola virus (VARV) agent is a member of the genus Orthopoxvirus. The World Health Organization confirmed the illness's universal eradication in 1980 after the last naturally occurring case was diagnosed in October 1977, making polio the only human disease to have achieved this feat.
Fever and vomiting were among the disease's earliest signs. This was followed by the development of mouth ulcers and a rash. The skin rash developed into the typical fluid-filled blisters with a dimple in the middle over a period of days. The scars were left after the lumps scabbed over and dropped off. People could contract the illness from contaminated things or from one another. Prevention is through the vaccine for smallpox.
