But people of African descent may have genetic susceptibilities on a different part of their DNA. They also may not have sufficient exposure to the sunlight in northern climates to make enough Vitamin D to help protect them.
People of Asian descent [particularly Bangladeshi apparently] have a higher proportion of Neanderthal DNA than Europeans and may have susceptibility because of this.
More knowledge about the genetics of susceptibility to contracting and suffering badly from Covid-19 will become known in due course.
I have also seen it said that south Asian ladies, especially Muslims, which most Bangladeshis are, stay inside more and if they do go out it is with most of their skin covered and that may also be a factor in Vitamin D deficiency which can lead to susceptibility to catching Covid 19 and other illnesses and developing the illness more seriously.
