John Hopkins University is one of the best universities in the world and has pioneered medical research for many years. this time also the university is exhausting all its resources to research the coronavirus and has come up with some trusted knowledge about the virus and the disease it is causing?
How long the virus can live on the surfaces?
- 72 hours on plastics
- 48 hours on stainless steel
- 24 hours on cardboard
- 4 hours on copper
- It is also detectable in the air for three hours.
The experimental aerosols used in labs are smaller than what comes out of a cough or sneeze, so they remain in the air at face-level longer than heavier particles would in nature.
What is the best way of protection against the virus?
You are more likely to catch the infection through the air if you are next to someone infected than off of a surface. Cleaning surfaces with disinfectant or soap is very effective because once the oily surface coat of the virus is disabled, there is no way the virus can infect a host cell. However, there cannot be an overabundance of caution. Nothing like this has ever happened before.
What are the CDC guidelines for prevention?
- Clean and disinfect surfaces that many people come in contact with. These include tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks. Avoid touching high-contact surfaces in public.
- Wash your hands often with soap and water for at least 20 seconds immediately when you return home from a public place such as the bank or grocery store.
- When in a public space, put a distance of six feet between yourself and others.
- Most importantly, stay home if you are sick and contact your doctor.
Why is it spreading so fast compared to other viruses?
SARS-CoV-2 which causes COVID-19 behaves like a typical respiratory coronavirus in the basic mechanisms of infection and replication. But several mutations allow it to bind tighter to its host receptor and increase its transmissibility, which is thought to make it more infectious.
The New England Journal of Medicine study suggests that the stability of SARS-CoV-2 is very similar to that of SARS-CoV1, the virus that caused the 2002-2003 SARS global outbreak. But, researchers believe people can carry high viral loads of the SARS-CoV-2 in the upper respiratory tract without recognizing any symptoms, allowing them to shed and transmit the virus while asymptomatic.
