The World Health Organization declared smallpox eradicated in 1980. If someone could acquire this virus and aerosolize it, could be highly infectious and contagious. There is an incubation period of approximately twelve days. A rash usually appears on the face, hands, and forearms, followed by the lower extremities and trunk. Venezuelan Equine Encephalomyelitis is only a mildly contagious disease.
Incubation period is approximately five days.
Birds and mosquitoes commonly spread it. Symptoms include but are not limited to, nausea, vomiting, cough, sore throat, high fever, general malaise, and pain in legs and lower back. In children there can be an inflammation of the brain, like in meningitis. Antibiotics have little if no effect, supportive care of the symptoms is the only treatment. Smallpox, Venezuelan Equine Encephalomyelitis and Viral Hemorrhagic Fevers are viruses that grow and reproduce by forcing the host to produce additional viruses.
