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 hadwashing and disinfecting to stop the spread of COVID-19. How often do you clean your smartphone? Has the pandemic permanently changed your approach to handwashing?
