Vector-borne parasitic infections after the earthquake

Abstract

The transmission of vector-borne infections after an earthquake is related to the changes in the environment caused by the earthquake. The displacement of thousands of people, especially in areas where vector-borne diseases are endemic, can significantly increase human exposure to mosquitoes and other vectors and the pathogens they may carry in overcrowded environments and inappropriate temporary shelters, leading to an increase in human infection cases. The devastating earthquakes in Türkiye on 6 February 2023 pose a risk of the spread and outbreaks of vector-borne infections such as cutaneous leishmaniasis (CL) and malaria, which are endemic in the region. Public health authorities should prioritise surveillance in all earthquake-affected areas. Immediate detection and identification of local vector species, monitor environmental conditions and potential breeding grounds, insecticide application and use of mosquito nets and development of interventions to prevent the emergence of vector-borne infections are essential. Case diagnosis and treatment follow-up, prophylaxis, training of the public and health personnel, improving temporary shelter conditions and facilitating access to clean drinking water and health services are essential to minimise the impact of vector-borne infections in post-earthquake situations.
