Louse-borne relapsing fever (LBRF) is an acute febrile illness endemic Ethiopia. To date reports of childhood LBRF are few. The demographic, social and clinical features of eighty children with LBRF admitted to Ethio-Swedish Children's Hospital, Addis Abeba between 1989 and 1991 is presented. The mean age of patients was 8.8 years (range 4 months to 15 years). The male to female ratio was 1.2:1. Seventy-seven (97%) patients came from Addis Abeba. They came from poor families living in overcrowded homes. Fever, headache, right upper quadrant pain, chills and rigors were common symptoms. Fever and hepatosplenomegaly were common signs. Three drug regimens were used in the treatment of patients. A combination of penicillin and tetracycline, chloramphenicol alone and erythromycin alone, all given for 3 days. There was only one death. The literature on LBRF in adults is reviewed and the results are compared (1).

Borrelia miyamotoi disease (BMD), also known as hard-tick relapsing fever, is an emerging tick-borne illness caused by the bacterium Borrelia miyamotoi. This pathogen is transmitted primarily by Ixodes ticks, also known as deer ticks or black-legged ticks. BMD poses significant public health concerns because of its potential to cause severe hemodynamic and hematologic disturbances, particularly in vulnerable populations such as pregnant individuals.

Poland suffered an epidemic of louse-borne typhus from 1916-1923, with 400,000 cases and more than 130,000 deaths. The causative factors were depressed economic conditions and a refugee crisis that engulfed Poland after World War I. The recognition of the epidemic in 1919 stimulated the creation of the League of Red Cross Societies (LRCS).

Nymphal and larval Amblyomma cordiferum ticks, a relatively rare species, were collected from the Malaysian house rat (Rattus rattus diardii) in Peninsular Malaysia. Redescription and molecular analysis of nymphs and larvae, based on the 12S rRNA, 16S rRNA, and COI genes, revealed divergence from A. cordiferum in Taiwan, suggesting that the Taiwanese tick specimens may represent a different taxon.
