Knowledge, Attitudes, and Practices Regarding Air Pollution among Medical Students.

Air pollution has emerged as a global public health concern. Specifically, in Medellín, Colombia, episodes of elevated air pollution have been documented. Medical students' knowledge of air pollution is paramount for implementing future interventions directed toward patients.

Comparison among plaque assay, tissue culture infectious dose (TCID) and real-time RT-PCR for SARS-CoV-2 variants quantification.

Background And Objectives: SARS-CoV-2 variants of concern (VOC) and interest (VOI) pose a significant threat to public health because the rapid change in the SARS-CoV-2 genome can alter viral phenotypes such as virulence, transmissibility and the ability to evade the host response. Hence, SARS-CoV-2 quantification techniques are essential for timely diagnosis and follow-up. Besides, they are vital to understanding viral pathogenesis, antiviral evaluation, and vaccine development.
