“As US’s premier gateway to China, California was, early in pandemic, seen as one of the most vulnerable states to the spread of virus.

In Jan, 600 direct flights from China carrying 150k people landed in the state, more than 2x as many as landed in NY.” https://www.nytimes.com/2020/04/14/us/california-coronavirus-shutdown.html
“But 2.5 months after first cases were detected in SoCal, scientists are scrambling to explain the CA conundrum:

The state, despite its large, globe-traveling population, ranks 30th in the US in coronavirus deaths per capita and has a fraction of the mortality rate of NY & NJ.”
“The reasons for the early promising signs in CA are numerous, experts say.

The state was the 1st to issue stay-at-home measures, and even before the orders came down, ppl were beginning to keep their distance from one another, while NYers were still packing bars & restaurants”
“Other factors include a work-from-home culture at many companies, spurred by tech industry; a dry and sunny Feb that brought people away from crowded spaces & into the outdoors; & even the fact that the San Francisco @49ers lost the Super Bowl, avoiding a crowded victory parade”
“California’s deep experience confronting natural disasters has also helped it address the pandemic.

Not only does the state have a vast government machinery in place to handle disasters, but its populace has experience following orders at a time of calamity.”
“Several experts are advancing another explanation, too:

Features that have long been viewed as liabilities — the state’s solitary car culture and traffic-jammed freeways, a dearth of public transportation and sprawling suburban neighborhoods — may have been protective.”
“Life in California is much more spread out,” said Eskin, chair of the department of computational medicine at the University of CA.

“Single-family homes compared with apartment buildings, work spaces that are less packed and even seating in restaurants that is more spacious.”
“Kraemer, scholar at Oxford, conducted a study with 12 other scientists across the world that relies on data from China. The study, which has not yet completed peer review, shows that more crowded areas had both higher coronavirus infections per capita & more prolonged epidemics”
“But CA still has numerous weak points, and experts stress that density is only one of many factors in the spread of a disease that is still poorly understood.

Nursing homes & other settings have been hit hard. Authorities discovered 102 cases at a single homeless shelter in SF”
“Some experts like Rutherford, a professor of epidemiology, put more emphasis on early government action in mitigating the spread of the virus.

Rutherford said nation’s first stay-at-home orders by officials in SF Bay Area, led by Santa Clara chief health officer, were crucial”
“Oakland hosted crowds between 500,000 to 1.5 million fans for the Golden State Warriors' three championship parades.

In 1918, during the Spanish flu pandemic, Philadelphia hosted a parade to boost wartime morale, leading to a sharp increase in cases among attendees.”
