Does coronavirus transmitted by insects?

What is coronavirus?

Coronaviruses are types of viruses that typically affect the respiratory tract of mammals, including humans. They are associated with the common cold, pneumonia, and severe acute respiratory syndrome (SARS) and can also affect the gut.

Insects and diseases

Insects (mosquitoes, lice, fleas, bed bugs) and ticks are able to transmit a number of diseases caused by infectious agents: viruses (chikungunya virus, yellow fever, dengue fever, etc.), bacteria (Lyme disease, plague, etc.), parasites (malaria, sleeping sickness, leishmaniasis, filariasis, etc.).


Till now (February 2020) coronavirus has no evidence that insects can transmit it, and only transmitted from human to human only.
However in 2017 scientists grew flu vaccine in insect cells which was a promising step in the vaccine production, because the normal way that is using eggs, is a time consuming process.

Protection

Facts on coronaviruses

• There is no cure for the common cold.

• A coronavirus causes both SARS and MERS.

• Coronaviruses infect many different species.

• There are seven known human coronaviruses.

• SARS spread from China to cause infection in 37 countries, killing 774 people

Transmission

Coronaviruses can spread in the following ways:

• Coughing and sneezing without covering the mouth can disperse droplets into the air, spreading the virus.
• Touching or shaking hands with a person that has the virus can pass the virus from one person to another.
• Making contact with a surface or object that has the virus and then touching your nose, eyes, or mouth.
• On rare occasions, a coronavirus may spread through contact with feces.
