17.1: Viral Infections of the Circulatory and Lymphatic Systems
- Identify common viral pathogens that cause infections of the circulatory and lymphatic systems
- Compare the major characteristics of specific viral diseases affecting the circulatory and lymphatic systems
Viral pathogens of the circulatory system vary tremendously both in their virulence and distribution worldwide. Some of these pathogens are practically global in their distribution. Fortunately, the most ubiquitous viruses tend to produce the mildest forms of disease. In the majority of cases, those infected remain asymptomatic. On the other hand, other viruses are associated with life-threatening diseases that have impacted human history.
Ebola Virus Disease
Hantavirus
Key Concepts and Summary
- Ebola virus disease is a highly contagious and often fatal infection spread through contact with bodily fluids. Treatments for patients with Ebola virus disease are limited to supportive therapies.
- Vector control and animal reservoir control remain the best defenses against most viruses that cause diseases of the circulatory system.
