The Los Angeles County Department of Public Health issued the voluntary mask advisory Monday, calling it a precautionary measure that was necessary until health officials could better understand how and to whom the Delta strain is spreading. Experts say research suggests vaccinations from Moderna and Pfizer/BioNTech provide significant levels of protection against the variant. Still, LA Public Health Director Barbara Ferrer says it’s unclear what the variant’s future will be as it grows more every day.
At this time, however, not all local leaders are implementing preventative guidance. According to a statement from the agency, “Until we better understand how and to who the ‘delta’ variant is spreading, everyone should focus on maximum protection with minimum interruption to routine as all businesses operate without other restrictions like physical distancing and capacity limits.”
Ferrer said last week that 123 cases of the “Delta” variety had been found in the county, about double the number from a week before. According to health officials, people who have been adequately vaccinated are considered to be immune to the variation. However, because the county only performs the minimal sequential testing required to discover the interpretation, she believes there are likely many more illnesses in the population.
