Virology & Epidemiology: Understanding COVID-19 & Beyond

This module covers virus basics: the difference between viruses and microorganisms such as bacteria; viral geometry and structural diversity; viral life cycles and replication. It also explains how viruses are classified and why this classification is important.

This module explains the three categories of viruses and their replication cycles. It covers how scientists use genomics and bioinformatics to identify pathogenic viruses, and takes a closer look at HIV and HPV. It also introduces the topic of COVID-19 vaccine development.

This module covers the human immune system, including innate and adaptive immunity. It explains how scientists identify viruses that have caused illness, and discusses vaccine development and testing, with a focus on the COVID-19 mRNA vaccine.

This module introduces disease ecology, explaining how pathogens emerge from nonhuman hosts into human populations. It covers the dynamics of disease spread, historical pandemics, and the safety and efficacy of COVID-19 vaccines.

This module explains how epidemiologists use computer modeling to monitor pandemic spread, evaluate control efforts, and guide policy decisions. It also covers health inequities in disease impact and future implications of mRNA technology.

This module examines the COVID-19 pandemic management in New York City, discusses the increasing frequency of spillover events, and explores strategies for preparing for future pandemics through testing, vaccines, surveillance, and treatment.
