Sleeping Sickness Definition Sleeping sickness (also called trypanosomiasis) is an infection caused by Trypanosoma protozoa; it is passed to humans through the bite of the tsetse fly. Once the protozoa are harbored in the salivary glands, they are ready to be deposited into the bloodstream of the fly's next source of a blood meal. These leaks in the blood vessels end up helping to further spread the protozoa throughout the afflicted person's body. I have sleep problem which affects me to a great extent. The first sign of infection with the trypanosome may be a sore appearing at the site of the tsetse fly bite about two to tree days after having been bitten.

The protozoa causing sleeping sickness are able to rapidly change specific markers (unique proteins) on their outer coats. The Rhodesian variety of sleeping sickness causes a much more severe illness, with even greater likelihood of eventual death than the Gambian form. Within the tsetse fly, the protozoa cycle through several different life forms; ultimately they migrate to the salivary glands of the tsetse fly. Need Help.I could not enjoy the blessings of nature.
