Since 1999, when it was first identified in the United States, the mosquitoborne disease West Nile virus has spread across the country. The virus has been widely distributed for years throughout Africa, the Middle East and West Asia, but with its appearance in the United States, the virus has threatened an immunologically naive population, with the elderly most at risk. Case counts have ranged from 62 in 1999 to almost 10,000 in 2003 to 5,600 in 2012 to 2,122 in 2014. Healthcare providers should be aware of how the virus is transmitted, the symptoms and how it can be spread in a healthcare setting. This module covers that information.


The goal of this continuing education program is to inform healthcare providers about West Nile virus. After studying the information presented here, you should be able to:
  • Describe the vector (mosquito), reservoir host (bird) and dead-end host (human) cycle of the virus
  • Describe the symptoms of West Nile encephalitis
  • Identify ways to diagnose West Nile encephalitis
  • Discuss ways to prevent mosquito bites

This is important, due to the fact that we work closely with the older population and who are at high risk to suffer from a more severe reaction to the WNV.
