Since the first coronavirus patient was confirmed in the U.S., the infection has affected all 50 states. However, some areas have coped to keep the numbers low.
The population density in the county is 3 people per mi2 (1 people per km2) so the risk of infection is below average. Even though the overall number of COVID-19 cases has increased up to 368 today, Sierra County still has the lowest number of cases and fatal cases in the state of California.
Los Angeles County and San Diego County are the state's leaders in coronavirus cases with 3,6M and 1M patients with confirmed infection accordingly, while Alpine County and Modoc County have the lowest number of coronavirus cases in California. Together with the latter ones, Sierra County’s per capita infection rate is regarded below average, but the coronavirus still remains a threat to public safety.
Please note, even if your area has a low number of confirmed cases, the virus is still active. Please stay vigilant and continue with good hygiene practices.
