In fall 2020, a coronavirus disease cluster comprising 16 cases occurred in Connecticut, USA. Epidemiologic and genomic evidence supported transmission among persons at a school and fitness center but not a workplace. The multiple transmission chains identified within this cluster highlight the necessity of a combined investigatory approach.

Background: Antiretroviral drugs are essential for preventing mother-to-child transmission (MTCT) of HIV in HIV-infected pregnant women. However, ART treatment for HIV-infected pregnant women with multidrug resistance remains a major challenge. Effective and safe ART regimens for preventing MTCT should be tailored to this special population.

Background: The resurgence of Anopheles funestus, a dominant vector of human malaria in western Kenya was partly attributed to insecticide resistance. However, evidence on the molecular basis of pyrethroid resistance in western Kenya is limited. Here, we reported metabolic resistance mechanisms and demonstrated that multiple non-coding Ribonucleic Acids (ncRNAs) could play a potential role in An.
