Vector-borne diseases are infections transmitted to humans through the bite
of vectors, which are transmitted by arthropods such as mosquitoes, ticks, fleas, and
mites. These zoonoses have become a major public health alarm affecting millions of
people globally. According to recent reports from the World Health Organization
(WHO), the estimated number of cases of vector-borne diseases, namely malaria and
Dengue, was 247 million and 390 million, respectively, with cases reported globally.
The change in environmental conditions like climate change with variations in the
temperature, humidity, rainfall, and precipitation has impacted the change in disease
dynamics. This chapter explores the relationship between the impact of climate change
and Scrub typhus as well as the risk factors that contribute to Scrub typhus and climate
change.
Keywords: Chigger mites, Climate change, Rickettsial infection, Scrub typhus, Seasonal change.
