Emerging viruses often pose a significant threat due to several reasons: - High Transmission Rates: Many emerging viruses have high _transmission rates_, making it easy for them to spread within communities and across borders. - Novel Pathogens: These viruses are often novel to the human immune system, leading to higher _morbidity_ and _mortality_ rates. - Lack of Preparedness: There is often a lack of specific diagnostics, vaccines, and treatments when a new virus emerges, complicating _public health_ responses.
