Lymphocytic Choriomeningitis ---------------------------- This viral disease can be transmitted from hamsters to people. A large number of cases in 1974 and 1975 were traced to a common infected hamster colony. Signs of this disease in people include recurrent fever, headache, fatigue, muscle aches, sore throat, rash and arthritis. The natural host in the wild for the causative virus is the rodent population. Hamsters would most likely acquire their infection from this source. Because hamsters are almost exclusively indoor pets, they are unlikely to become infected with the virus. Hamster owners must, however, restrict contact between their pets and orphaned wild rodents that have been adopted.
