Emerging and re-emerging viral infections, which include outbreaks of previously unknown pathogens or new strains of known viruses, continue to pose significant threats and challenges to human well-being globally. The convergence of these known and other less known viruses contributes to a variety of factors that enables them to expand their spectrum of activity. Such factors include mutations, the development of environmental conditions that help to spread the disease agents, the availability of an ever increasing range of susceptible hosts, and the lack of effective laboratory detection testing methods. An awareness of these factors together with current knowledge of their existence and effects is essential to control and prevention.

Adding to the dangers posed by emerging viral diseases is the appearance of new strains of many known pathogens in more virulent forms. Widespread travel, the globalization of food supplies, and the increasing overlap between the environments of humans and lower animals give viruses, as well as other microorganisms, rapid and easy access to new populations. Unfortunately, newly recognized pathogens are accelerating their distribution by spreading faster and further, affecting the security of nations and the global economy.

This intermediate-level course is geared toward all levels and disciplines of healthcare and public health professionals. The course provides information about recently discovered and reoccurring viruses. Knowledge of the origin, pathogenesis, and diagnosis of these viruses may aid in reducing the prevalence of the infections they cause.
