Article Synopsis
- Hunting activities in Mayan communities increased during COVID-19, leading to a rise in the relevance of domestic dogs as carriers of tick-borne diseases (TBDs) to humans.
- A study was conducted in March 2021 in Teabo, Yucatan, where ticks were collected from domestic dogs to identify TBDs through morphological identification and DNA analysis.
- The results showed 33 ticks collected from 11 dogs, with the most common being one species identified at 66%, confirming the presence of specific TBDs for the first time in Yucatan.

Hemophagocytic lymphohistiocytosis is a rare complication in Rickettsia typhi infections. We report the case of a 2-year-old boy with sudden night-onset fever, pallor, neck adenopathy and erythematous macular rash on the thorax, thighs and buttocks. During admission, he developed hyponatremia, hypoalbuminemia, anemia, thrombocytopenia, leukopenia, neutropenia, liver damage, hemorrhages and persistent fever.

We aimed to determine the knowledge, attitudes, and practices related to the exposition and prevention of tick-borne diseases among people living in a typical Mayan community of Yucatan, Mexico between Dec 2012 and May 2013.
Methods: A directed survey was applied to 212 (100%) householders (women and men) from Teabo, Yucatan, Mexico.
