Emerging neuroinfectious diseases: public health implications

Abstract

Purpose of review: Direct neurological consequences from emerging and re-emerging infectious diseases such as poliomyelitis, West Nile virus and Zika virus, and those with indirect neurological effects such as COVID-19 and Influenza, are major contributors to the profound impact of infectious diseases on global human health. Here, we highlight select infections of the nervous system of public health significance and discuss some of the key factors of emergence. We focus on vector-borne infections including Oropouche virus and West Nile virus, those transmitted by other nonvector animal species including Nipah and Hendra virus, and vaccine preventable infections including neurological effects of Measles virus.

Recent findings: Currently, the emergence of Oropouche virus, Avian Influenza, and the re-emergence of Measles outbreaks across Europe and America, are examples of current emerging infectious disease outbreaks. As pathogens spread to new areas, we will continue to see a rise in populations at risk of severe neurological effects. The recent resurgence of measles virus cases exemplifies the importance of strong vaccination programs and preventive public health measures to mitigate the impact of preventable re-emerging infections in vulnerable populations.

Summary: Neuroinfectious diseases will continue to drive significant morbidity and mortality on global populations as risk factors remain high, and global public health initiatives are hampered by inadequate governmental support.
