The
coronavirus pandemic that has infected more than 125,000 people around the world is concentrated in a “corridor” across the northern hemisphere, researchers said, as more studies focused on how temperature and humidity could be used to predict the spread of the contagion.
Despite worries that Southeast Asia may become a coronavirus hotspot after central China (where the Covid-19 outbreak started) because of their proximity and travel connections to the infection’s epicentre, more countries and regions like South Korea, Japan, Iran, northern Italy and the northwestern United States may have to bear the heaviest burden.
“The establishment of community transmission has occurred in a consistent east-and-west pattern. The new [regional] epicentres of the virus were all roughly along the 30-50 degree [lines of latitude] north zone,” according to a team of US and Iranian researchers.
