Well being officers say that almost 900,000 individuals have probably been contaminated twice with Covid as much as the beginning of April. Nevertheless, it’s onerous to offer a exact quantity as a result of not all constructive assessments undergo the entire genome sequencing wanted to verify if infections are from completely different strains.
