The infection rate increased in Valga County by 14.9 percent pushing the region's R rate to 1.05. The rate fell in Pärnu, Ida-Viru and Tartu counties.
The number of new patients fell in all age groups except the over 80s, which increased by 7 percent. The largest increases were in Valga and Ida-Viru counties where the infection rate of over 80s in the lowest. The virus was mostly spread by family members or in health care institutions.

This is similar to the week before.
