While attention has been focused on the worrying new variants of SARS-CoV-2, there has been some good news: despite the evolution of a number of strains that appear to spread more readily, total COVID-19 cases have been dropping, both in the United States and globally. While there are a number of nations that are still seeing an increase in infections, a combination of reduced post-holiday spread and increased social interventions appear to be getting the surges seen in January under control.

That said, there are worrying signs that, at least in the US, a number of states are making the same mistakes that ensured that the virus never really went away after the first surge in cases. And the spread of many new variants drives home the need to avoid complacency.

The general fall in cases came up at a recent press briefing from the World Health Organization. "For the third week in a row, the number of new cases of COVID-19 reported globally fell last week," said WHO Director-General Tedros Adhanom Ghebreyesus. "There are still many countries with increasing numbers of cases, but at the global level, this is encouraging news."
