Long Covid
On 4 March, Los Angeles County lifted its indoor mask mandate for covid. This was after California had lifted its state mandate. Margan and I went to REI today for some hiking shoes. We were masked and I estimate that about ½ to ⅔ of the people we saw inside were also masked – leaving a high proportion who were not. The national data and the LA County data all show falling numbers of cases, hospitalizations, and deaths , with numbers among the lowest troughs seen during the pandemic. However, the BA.2 omicron variant represents ever more of the cases seen , likely because it is more transmissible than the BA.1.1 variant and immunity from vaccines and prior infections wanes with time. The WHO reports BA.2 is now the dominant variant worldwide at 85% of isolates sequenced. Wastewater surveillance shows many communities have BA.2 being shed into sewage nationwide. At the same time, uptake of vaccines has fallen to very low levels in the United States – less than 160,000 doses daily
