How often do you Clean your Cellphone?

Researchers in Australia say the novel coronavirus can survive for nearly a month on some surfaces – including smartphones.
The virus remained infectious for up to 28 days on smooth surfaces like glass, stainless steel, or plastic – which includes smartphone screens and credit cards. By comparison, the Influenza A virus survives only 17 days.
Scientists say it reinforces the importance of handwashing and disinfecting to stop the spread of COVID-19.
