Ebola and hantavirus are emerging again as serious health threats due to their rapid development from flu-like symptoms to deadly conditions.
Hantavirus, often spread by rodents, can cause severe heart and lung issues. It currently has no specific treatments or vaccines. Some hantavirus strains can transmit between humans, raising risk levels.
Ebola remains one of the most lethal viruses, with outbreaks killing up to 50% of infected patients. However, recent vaccines and antiviral treatments have improved survival rates for several strains.
