Accordingly, this takes total number of cases of the delta variant to 68.
“Though total number of cases is at 68, there may be more such cases which are undetected in the community,” Deputy Director-General of Health Services Dr Hemantha Herath told Daily Mirror.
"What should be done is to strictly adhere to health practices. It is apparent that many more cases of Delta variant would be found in future too," he added.
