Influenza Virus (Seasonal Flu and Pandemic Flu): Influenza can cause widespread illness and can be severe, especially for vulnerable populations like the very young, elderly, and individuals with underlying health conditions. Influenza pandemics, such as the 1918 Spanish flu, have resulted in millions of deaths.
SARS-CoV-2 (COVID-19): The coronavirus responsible for COVID-19 emerged in late 2019 and quickly became a global pandemic. It has caused significant illness, death, and economic disruption worldwide. The virus has been particularly dangerous for older adults and individuals with certain pre-existing health conditions.
It's essential to note that the impact of a virus can be influenced by various factors, including public health measures, healthcare infrastructure, and the availability of vaccines and treatments. Efforts to monitor, prevent, and treat infectious diseases remain critical in mitigating their impact on human populations. For the most current information on the dangerous viruses, it's best to refer to updated data from reputable health organizations like the World Health Organization (WHO) or the Centers for Disease Control and Prevention (CDC).
