The term 'Encephalitis Cause' can be summarized by the 6-letter word 'TSETSE'. TSETSE flies are blood-sucking insects found in Africa that transmit a parasitic disease known as sleeping sickness. The disease is caused by a protozoan parasite, which is transmitted to humans and other animals through the bite of an infected TSETSE fly. This parasite can cause encephalitis, an inflammation of the brain, which can lead to severe neurological symptoms and even death.
