(CNN) The stay-at-home order in California has ended, but a top Los Angeles health official worries that another spike could be on the horizon as Covid-19 variants spread and the supply of vaccines struggles to meet the demand. State officials in California, a recent epicenter of the pandemic in the US, lifted the regional stay at home order for all five regions on Monday in light of expectations that the ICU bed capacity would meet a key threshold in four weeks. Trends are moving in a positive direction as well in Los Angeles County, which has more than halved its number of daily positive cases since reaching a peak earlier in January, said the county's public health director Barbara Ferrer. But she warned that coronavirus variants pose an increasing threat. "They will become dominant and will make it easier for people to become infected and lead to a surge," Ferrer said, while urging residents to remain vigilant.
