At the very least 38 individuals, most of them kids and youngsters, have died since early June 2024 within the worst outbreak of Chandipura virus in India in over 20 years.
This rod-shaped pathogen is a member of the rabies virus household that causes encephalitis – irritation and swelling within the mind. And it’s unfold primarily by sandflies, however mosquitoes and ticks may unfold it.
The preliminary signs are much like the flu, however they will quickly advance (over 24 to 48 hours) to encephalitis, coma and loss of life. Youngsters underneath the age of 15 are probably the most susceptible.
Precisely how the virus enters the central nervous system and causes encephalitis is poorly understood. It has been proposed that when an contaminated insect bites an individual to get their blood meal, they secrete their saliva containing the virus.
The virus then spreads into the particular person’s bloodstream and infects immune cells known as monocytes (a kind of white blood cell), the place it replicates, undetected by the immune system. The virus then will get transported to the central nervous system and enters the mind by disrupting the protecting blood-brain barrier.
Six hours after the particular person has grow to be contaminated, the Chandipura virus secretes a protein known as phosphoprotein inside mind cells, and this may clarify why it causes loss of life so quickly.
Sadly, there aren’t any antiviral medication to deal with individuals contaminated with the Chandipura virus. And there’s no vaccine.
