Can cold viruses survive in freezing temperatures?

No, cold viruses cannot survive in freezing temperatures. Most cold viruses are enveloped viruses, meaning that they have a lipid membrane that surrounds the virus particle. This lipid membrane is essential for the virus to enter and infect host cells. However, the lipid membrane is also very fragile and can easily be damaged by cold temperatures. When cold viruses are exposed to freezing temperatures, the lipid membrane can rupture and the virus particle will be destroyed.

In addition, cold temperatures can also cause the proteins on the surface of the virus particle to denature, which means that they can no longer bind to host cells. This also prevents the virus from infecting host cells.

Therefore, cold viruses cannot survive in freezing temperatures and are most commonly spread during the colder months of the year when temperatures are more moderate.
