Common JC Virus Could Activate and Destroy Brain, Researchers Find
The John Cunningham virus, or JC virus, infects most people and usually remains dormant. Researchers reported this week that a new activation method could affect 10 percent of adults worldwide, leading to brain destruction.
The John Cunningham virus, or JC virus, is a common virus that quietly infects an estimated 50 to 90 percent of adults. The virus, first isolated in 1971, is typically contracted early in life through the fecal-oral route and is shed in urine and stool. Initial infection by the archetype JC virus is believed to occur in the tonsils or gastrointestinal tract, remaining asymptomatic. For most people, the JC virus remains a silent, lifelong infection. However, researchers reported this week a new activation method could affect up to 10 percent of adults worldwide.
Key Facts
- The JC virus, or John Cunningham virus, can destroy the brain if activated.
- The virus spreads through the fecal-oral route and shows up in the urine and stool of infected people.
- Between 50 and 90 percent of adults are thought to be infected with the JC virus.
- The initial JC virus infection is asymptomatic.
- The primary infection site is suspected to be the tonsils, or the gastrointestinal tract.
- The JC virus was first isolated in 1971.
- A new activation method could affect up to 10% of adults worldwide.
