SAN DIEGO–The number of younger San Diegans getting infected with the novel coronavirus has been increasing in recent weeks, and more of them are landing in the hospital, according to the County Health and Human Services Agency.

Enjoying the sales revenue when customers pack a store means implementing systems to guarantee they come back. Line Busting refers to tactics retailers take to streamline check out lines, reduce line waiting for customers, and improve the flow of business.

Of the nearly 21,500 COVID-19 cases reported in the region, San Diegans between 20 and 39 years of age represent nearly 44% of all cases.

A closer look at the Health and Human Services Agency data shows that after restaurants, bars, wineries, breweries, hotels and other businesses reopened, the number of people between 20 and 39 years of age getting sick with COVID-19 began to rise rapidly.

During the second week of June, 510 San Diegans in that age bracket got sick with COVID-19. Another 1,144 got sick the following week, and during the last week of June the number jumped to 1,595. The figures began to decrease again when indoor activities at those same were closed again. The total was down to 1,028 by the week ending July 11.

“Some young people think they’re invincible and won’t get sick, but that’s not the case,” said Wilma Wooten, M.D., M.P.H., County public health officer. “Not only are they getting sick, but they are also ending up at emergency rooms and needing hospitalization.”

During the second week of June 10, a total of 16 San Diegans between 20 and 39 years of age were hospitalized. The figured dropped to 12 the following week and jumped to 27 the last week of June. Again, the number began to decrease when certain sectors of the economy were closed and was down to 18 by July 11.

Also, the number of COVID-19 outbreaks in community settings followed a similar pattern of increasing as activities widened. While only eight community outbreaks were reported in May, in June, 33 were identified. This month, 38 community outbreaks have been reported, with restaurants/bars and private residences the most common locations.

“The evidence is clear. As more people started to go out, especially young people, we started to see an increasing number of COVID-19 cases,” Wooten said.

Dr. Scott Eisman, a pulmonary disease and critical care medicine expert at Scripps Memorial Hospital in Encinitas, said that while young people think COVID-19 is not serious, the novel coronavirus could have serious health issues, especially in young people who smoke or vape.

“Many younger people think that this is something that you’ll get, and you’ll overcome, and everything will be fine, but the complications of this illness are greater than the flu,” Eisman said. “We have younger and younger patients showing up with more and more significant complications.”

Eisman said research has shown that COVID-19 attacks both lungs and their blood vessels which could result in blood clotting in the lungs and other parts of the body.

COVID-19, Eisman said, can cause other problems, including stroke, cardiac issues, cerebral dysfunction, liver and kidney failure.

“It causes blood clotting in general and that could create substantial problems in the ability of the lung to deliver oxygen,” Eisman said.

Due to the increasing number of COVID-19 cases, the County is hiring additional people to do case investigations, an important activity in public health responses to infectious disease.

Case investigators call or email people who have tested positive for COVID-19 to ask them to isolate themselves and find out their close contacts. Bilingual applicants are encouraged to apply for the temporary position.

The new hires will join the more than 510 case investigators and contact tracers currently working to stop the spread of the virus.
