Transfusion malaria as a consequence of the 1974 war between Turkey and Greece--two cases.

Two cases of transfusion induced Plasmodium malariae malaria that occurred in August and September 1974 in New York City were direct results of the outbreak of war between Turkey and Greece on the island of Cyprus in July 1974. The cases could be traced to two Greek immigrants with latent infection (one being the longest ever recorded) who independently donated blood after solicitation for people in need living in the country of their ancestors. In view of current rules for donor acceptability, attention should be directed domestically towards careful surveillance for an increased occurrence of transfusion malaria.
