Human and Environmental Reservoirs of Intestinal Parasites in the City of Yaoundé, Cameroon: An Update in the Context of COVID-19 Pandemic

Aims: Intestinal parasitic infections are persistent in Africa, and we questioned here whether prevention measures imposed by the occurrence of COVID-19 pandemic 2020 could alleviate this threat lowlands city Yaoundé, Cameroon. 
 Study Design: We monitored trend intestinal parasites human environmental samples from seven subdivisions Yaounde, before (November-December 2019) during (July-August 2020, November-December 2020) pandemic.
 Methodology: Parasitological analysis were performed to check for presence helminths protozoans stools inhabitants as well water, soil fresh vegetables, using standard Kato Katz Formol Ether methods.The minimum effective sample size considered estimation parasite richness, infection contamination indexeswas 30 (i.e. soils, water vegetables) per location.
 Results: Of 19 species identified environments, twelve protozoans. The overall richness reached 16 2019 (12 4 protozoans) 7 protozoans), with about 62.5-68.4% shared environments. frequencies (21.03%) water/soils (32.3%) did not differ statistically those (14.6-20.3% 10.8-35.4%, respectively). rate vegetables carrots, lettuce, basil, celery, etc.) has increased (6.1-9.1%) (9.1-24.2%), was frequently due roundworms, hookworms, Entamoeba Cryptosporidium cysts. findings suggest risk associated irrespective study locations.
 Conclusion: current control approaches may therefore integrateecological epidemiology complementary strategy African cities.
