Abstract
Background: Pan American Health Organization (PAHO) indicated guidelines on the prevention and control of dengue during the COVID-19 pandemic, reinforcing the surveillance and control of its vectors: Aedes aegypfi and Aedes albopictus.
Objective: To evaluate the larval indices and others entomological indicators in high risk blocks in Havana in order to rationalize the efforts in entomological surveillance, speed.
Methods: The study was carried out in four municipalities (Playa, Plaza de la Revolución, Habana Vieja y Arroyo Naranjo) belonging to Havana province in Cuba. In each municipality, the surveillance took one week, visiting 33% of the total number of houses in each neighborhood. The surveillance was conducted from March 5 till April 2, 2019.
Results: A total of 6 647 containers were inspected from 1599 (Houses total sampled in Plaza de la Revolución municipality was 399) houses in the four study areas of which only 500 (7.5%) were positive for Ae. aegypfi immature stages. Aedes infestations levels was high with a general Breteau Index (BI) of 31.3 a Container Index (CI) of 7.5 and a House Index (HI) of 18.3 respectively. All municipalities showed mainly presence inside the houses with preference in living room and kitchen.
Conclusions: This type of sampling in the neighborhoods with high risk for Ae. Aegypfi in Cuba would help the sustainability of the program at a time of COVID-19 when human, material and financial resources are limited since it would focus interventions more towards prevention and control in the event of dengue transmission.
