Early in the pandemic, it became clear that the population was dense. Low-income areas increased caseloads with faster clips than wealthy areas.. But even now, health officials are often uncertain about why certain communities are booming. Dr. Barbara Ferrer, director of the Los Angeles County Public Health Service, said earlier last month. Pacoima, Sun Valley And Palmdale. She couldn’t pinpoint exactly what caused the spread In those areas.

Professor Neeraj Sood of the Price School of Public Policy at the University of Southern California said the situation on the ground is changing rapidly and is difficult to track.

“I haven’t seen any studies identifying the source of the infection,” said Sood, who works with the Los Angeles County Public Health Service on several studies. “It seems to be everywhere and can be obtained in various ways.”

Even within one neighborhood, “things can change quite dramatically and quickly,” he said.

Sood is conducting a field survey at the COVID-19 test facility in the San Fernando Valley. Just before Thanksgiving, his team recorded a positive rate of 5-6% at the facility. Last week it soared to 27%.

One factor, according to Sood, is that the areas struck during the first wave are more resistant as people already infected with the virus develop immunity to the virus. However, places that were only slightly affected during the first few months of the virus are now at greater risk.

“It was an area that was unaffected by the first wave and is now 100% vulnerable to the population,” he said. “Some of them are definitely happening.”

In fact, when COVID-19 first began to spread in March and early April, The highest prevalence was in the wealthy areas of Los Angeles. Residents of these areas were likely exposed to the virus from their trips. In addition, experts say that wealthy residents have had more access to test kits before they became widely available.

Crosstown uses the neighborhood boundaries defined by Los Angeles Times.. In some cases, the Los Angeles County Public Health Service refers to areas with different boundaries. When possible, we adjusted the boundaries to comply with the Public Health Service. In some cases, the definition of departmental boundaries is unclear. We did not include community data if there was uncertainty about the boundaries.
