The reproductive (R) number indicates the average number of other people who become infected from one person carrying COVID. If it did not increase further, according to Dušek's presentation, it indicates that there could be about 114,000 newly infected in December. "If the reproduction (R) number rises to values above 1.2, we will inevitably monitor the escalation," he said. In that case, there would be about 198,000 newly infected people by the end of December.
