Polio News and Research

RSS

Poliomyelitis (polio) is a highly infectious disease caused by a virus that invades the nervous system and can cause severe paralysis. The virus enters the body through the mouth and multiplies in the intestine. Initial symptoms are fever, fatigue, headache, vomiting, stiffness in the neck, and pain in the limbs. One in 200 infections leads to irreversible paralysis (usually in the legs). Among those paralyzed, 5-10% die when their breathing muscles become immobilized. Polio mainly affects children under five years of age. Naturally occurring polio was eliminated in the U.S. in 1979 and in the Western Hemisphere by 1991; however, worldwide efforts are continuing towards eradication of this contagious and devastating disease.

Using wastewater epidemiology to monitor SARS-CoV-2 in Houston

Now, a team of researchers at Rice University, Baylor College of Medicine, and the Houston Health Department show SARS-CoV-2 RNA wastewater levels to be a strong predictive of trends in the nasal positivity rate two weeks in advance. This could help track the positivity rate for populations, speeding up the isolation and treatment of infected people.
