Explain why an envelope virus that simply leaks out of an infected cell can be worse than a virus that quickly lyses and kills t
o-na [289]

Answer:

The enveloped viruses are resistant to disinfectants.

Explanation:

The outer covering or the envelope in the virus comes from the infected cell. This envelope is formed by the process called as budding off, from the host cell. The envelope that covers the virus provides resistance to various disinfectants and prevent virus from damage. The outer coat (envelope) is formed of a small part of cell membrane.

The virus that lyses and kills the cell immediately is less worse than the enveloped virus. The virus that kills cells immediately prevents the host cell from continuously synthesizing new virus particles. Thus, no more viral particles can be produced by the host cell. So, envelope viruses are worse that viruses that directly kills the host cell.
