Globally, the total confirmed cases of Covid-19 have reached over 116,879,000, with more than 2,594,000 deaths and 76,967,000 recoveries.

The US, India, and Brazil lead the world for total confirmed Covid-19 cases, with India maintaining its lead ahead of Brazil by only 200,000 cases.

Brazil now leads the world in the number of daily new confirmed cases, with over 468,000 new cases confirmed in the past seven days.

Daily new cases appear to be trending upwards within India as well as Brazil.

However, even though cases continue to decrease across the US, numbers there are rapidly approaching 29 million.

A recent study has found that secondary transmission within schools may be less common than that seen within the community when the appropriate mitigation policies are implemented.

The study took place over a nine week period of in-class teaching across 11 school districts in the US state of North Carolina, registering a total of 32 SARS-CoV-2 infections within schools compared to 773 community-based transmissions.

Schools within the study were participating within an educational program focused on prevention and transmission of infection, aimed at administration, teachers and parents of students.

These data could support the re-opening of schools provided adequate control measures are in place.
