Wolf's Brother

NOTES

The Reindeer Fly is an insect that afflicts reindeer by laying eggs on their hide that develop into larvae. The larvae burrow into the animal's back. Boils develop around them, and the larvae live off the pus within the boil until the following spring.

Sometimes the fly will hover near the reindeer's muzzle, to inject minute larvae in a glutinous liquid into the muzzle. When this happens, the larvae are inhaled and a stream of larvae make their way on the nasal mucous to the throat. Animals thus afflicted often die of a cough, cold, or asphyxiation. This is the condition referred to in the story as the Great Plague. Reindeer usually escape the flies by seeking the ice fields that remain intact on the tundra even in summer.

Tularemia is an acute, plaguelike infectious disease, caused by the Francissella tularensis. It can be transmitted to man by the bite of an infected tick or other bloodsucking insect, or by direct contact with infected animals, or by consuming inadequately cooked meat or drinking water that contains the organism. Symptoms appear one to three days afterwards. Symptoms include headaches, chills, vomiting, fever, and aching pains. The site of infection may develop into an ulcer, and the glands at the elbow and armpit may become enlarged and painful. Later, it may develop into an abscess. Sweating, loss of weight, and general weakness follow. The fever may come and go over a period of several weeks. If the bacteria enters through the skin, local sores occur at the site, usually on the hands and fingers. The most common complication is pneumonia. Wet saline dressings are generally soothing to the lesions, and analgesics relieve the headaches.
