The Risks of an Accidental Introduction and/or Transfer of Plague: Conditions prevalent in the East African Ports of Tanga and Mombasa

Abstract

Rodents were trapped at Tanga and Mombasa seaports. Bacteriological, bio­ logical and serological tests were performed on the captured animals. 22.6% of the rodents caught at Tanga had significant antibody levels for plague. Only 1.9% of the rodents trapped at Mombasa seaport were serologically positive for the disease. The above findings were discussed in the light of the presently applied anti rodents and antiplague measures and the conclusion was reached that the disease could be carried through the East African seaports. A stricter adherence to the International Health Regulations by the Shipping Companies would be desirable
