Germany’s coronavirus reproduction rate has fallen to 0.75, according to the country’s disease and control center — a small but hopeful decrease.

It had previously been 0.81, according to the Robert Koch Institute.

The reproduction rate, also known as the R-value, indicates how much the virus is spreading; an R-value of 1 means each infected person is transmitting it to one other person.

German Chancellor Angela Merkel has repeatedly warned that if the number rises above 1, the country’s health system would eventually be overwhelmed.

The Robert Koch Institute says a total of 3.1 million coronavirus tests have been carried out in Germany since the outbreak began.

The country has reported 174,478 cases and 7,884 related deaths, according to data from Johns Hopkins University. But this doesn’t reflect the total number of active cases; at least 151,700 people have recovered from the virus, according to the institute.
