Do you know the difference between insect virus and COVID-19?
| SARS-CoV-2 | Insect virus | |
|
Safety |
Infect people |
Only infecting insects, all insect viruses that enter the market for sale have undergone national safety evaluations |
|
Route of infection |
Droplets, contact, etc |
Gastric toxin (can only be ingested) spreads from the digestive system to cells throughout the body |
|
Resistance |
Weak, sensitive to heat and ultraviolet radiation |
Strong, can survive for up to 5 years in nature, and virus particles are protected by armor outside |
|
Mortality |
2%以内 Relatively low (high for humans) Within 2%
|
High, as long as the infection is irreversible, it will lead to death |
The biggest difference here is that insect virus particles are protected by polyhedra (armor) on the outside, making them highly resistant to stress, and high mortality rate. The largest family of insect viruses is baculovirus, including nuclear polyhedral viruses and granular viruses. Nuclear polyhedral virus refers to one or more insect virus particles that are protected by a protein (the armor of the virus particles).
