Increased Seroprevalence of Typhus Group Rickettsiosis, Galveston County, Texas, USA

Emerging Infectious Diseases, 2023
Whether increases in typhus group rickettsiosis in Galveston County, Texas, USA, are caused by increased recognition or true reemergence is unclear. We conducted a serosurvey that demonstrated Rickettsia typhi antibodies increased from 1.2% in 2013 to 7.

The First Report on Cat Flea (Ctenocephalides felis), a Zoonotic Haematophagous Insect Infestation in Humans in Bangladesh: A Case Report and Literature Review

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
An 18‐year‐old girl who didn't have any pets but was infested with fleas from a pet‐owning neighbour. Flea‐bite dermatitis caused severe pruritus, urticarial and papulomatous lesions on the neck and arm. Fleas were removed and identified as Ctenocephalides felis, the cat flea.

Estimating scrub typhus and murine typhus incidence among adolescents and adults in Yangon, Myanmar

Tropical Medicine &International Health, Volume 30, Issue 9, Page 978-986, September 2025.
Abstract Objectives Rickettsioses are frequent causes of treatable febrile illness in Southeast Asia, including Myanmar. Accurate estimates of the incidence of rickettsioses are needed to inform investments in disease prevention and control. We sought to estimate the incidence of rickettsioses among adults and adolescents by combining sentinel hospital
