The only successful infectious disease eradication that has occurred so far in human history was the eradication of smallpox but eradicating other viral diseases should be possible. What characteristic of viruses makes it easier to eradicate viral diseases compared to bacterial or eukaryotic diseases? A. Viruses require a host to replicate, so if all hosts are made immune to the virus then the virus will go extinct B. Viruses are relatively easy to destroy with disinfectants and antiseptics C. Viruses can only be spread by direct contact, so isolation of the infected can always stop viral diseases quickly and easily All the above B and C

Answer

A Explanation 1. Analyze Option A Viruses require a host to replicate. If all hosts are immune, the virus cannot survive, making eradication possible. 2. Analyze Option B While some viruses can be destroyed with disinfectants, this is not universally true for all viruses. 3. Analyze Option C Not all viruses spread only by direct contact; some spread through air or vectors, so isolation isn't always effective.
