SINGAPORE — According to Singapore's The Strait Times, COVID-19 has an infection number between 2 and 3 globally, meaning each patient infects two or three more people.<br /><br />The newspaper reports the infection number in the city-state has dropped to 1 since the government-ordered lockdown on April 8, citing Alex Cook, associate professor of public health at the National University of Singapore.<br /><br />By limiting exposure to carriers, social distancing could slow the spread of COVID-19, even if the biological factors remain hard to tackle.<br /><br />Cook was cited as saying Singapore's confirmed cases have risen to 1,481 as of April 7.<br /><br />However, he claims most were imported and Singapore should be able to control the disease if the nation shuts its borders.
