Things are so bad in Los Angeles County that health officials are now advising all essential workers to wear masks inside their own home to prevent spreading Covid-19 within their household.”Right now, because there is so much spread, we’re recommending that people wear their face coverings while they’re inside the home,” Los Angeles County Director of Public Health Barbara Ferrer said in a news conference Monday. That’s for people who are either leaving their home every day for work or who are running errands regularly for their family, Ferrer said.Doing so, she said, “will add a layer of protection while we get through this surge.”
