Week 28 will be recorded as a watershed in the perception of SARS-CoV-2 transmission risk: yes, the virus is transmitted by fat droplets, and yes, it is also transmitted tiny aerosol particles. If this shift is proven to be right, SARS-CoV-2 may go down in history as the virus that unified the almost century-old dichotomy of droplets vs. aerosol transmission. The merit goes to Lidia Morawska and Donald K. Milton, supported by 237 scientists (see also the comment in The Guardian and in The New York Times). In the next days, we will publish an update of our Transmission chapter.

WHO update information about SARS-CoV-2 transmission (WHO 20200709): “There have been reported outbreaks of COVID-19 in some closed settings, such as restaurants, nightclubs, places of worship or places of work where people may be shouting, talking, or singing. In these outbreaks, aerosol transmission, particularly in these indoor locations where there are crowded and inadequately ventilated spaces where infected persons spend long periods of time with others, cannot be ruled out.”
Catalonia orders wearing face masks even when the required 1.5-metre social distancing can be observed. The fine for not observing the new rules: 100 euros. The Balearic islands is set to follow Catalonia’s lead soon.

Is the governor of the hard-hit Lombardy region (almost 50% of all Italian cases) opening the dance for the second wave in his country? In a bold (suicidal?) move he allows discos to reopen open-air discos. The Repubblica newspaper reports that people “filled the slopes of the main Milanese discos without wearing personal protective equipment and without respecting the social distancing.” The countdown has begun.
