Coronavirus can survive on surfaces , a cause of worry ?

Have you wondered that you touch a lot of objects in day-to-day basis without even noticing? Objects like money, phones, door handles, elevator buttons, cups, desks, keyboards, petrol pumps and shopping trolleys. Objects with surfaces that carry pathogens (such as bacteria or viruses) can pass on infections when we touch them.

So it makes sense that contact with these contaminated surfaces (often called “fomites”) might increase our infection risk.

A recent study showed that Coronavirus can survive for 28 days on some surfaces. This caused panic in general public. The data presented in this study demonstrates that infectious SARS-CoV-2 can be recovered from nonporous surfaces for at least 28 days at ambient temperature and humidity (20 °C and 50% RH). Increasing the temperature while maintaining humidity drastically reduced the survivability of the virus to as little as 24 h at 40 °C.

CSIRO researchers said that at 20 degrees Celsius (68 degrees Fahrenheit) the SARS-COV-2 virus was “extremely robust” and remained infectious for 28 days on smooth surfaces such as plastic banknotes and glass found on mobile phone screens. The study was published in Virology Journal.

Now, The question here is whether the findings of the study are worth panicking or not?

Though, The study reveals the survival of virus can be as long as 28 days on surfaces but how much is this effective and certain in daily life.

The study was designed to mimic the spread of the virus indoors on surfaces under dark conditions only. In many countries, 28 days of darkness would not be considered normal. Real-life conditions include a whole host of other factors such as light, variations in temperature, or wind generated by air conditioners, fans, etc.

Many of the object surfaces we touch certainly deserve consideration as sources of SARS-CoV-2 transmission. However, how long the virus survives on them depends on several environmental and other factors, not all of which researchers have sufficiently studied.There are alot of factors like light,humidity, UV rays etc.

As such, it is important not to read too much into the findings while remaining cautious of the virus’ resilience. The probability of catching the virus from direct contact with a contagious individual still remains markedly higher than catching it via contaminated surfaces.

The hygience practices are still must. We need to keep washing hands and follow all the guidelines by World Health Organisation (WHO). Take precautions in place of being panicked.
