San Diego-At the Embarcadero in San Diego, the pace is picking up.

Entering the holiday weekend of July 4, the traffic volume of walking and driving has increased significantly, and the area is expected to attract a large number of tourists. But before the weekend celebrations, there were growing concerns about the emergence of the highly contagious delta variant of the coronavirus.

The variant is spreading across the United States, and states such as Missouri, Colorado, and New Jersey have been hit hard. This prompted the World Health Organization to urge vaccinated residents to continue to wear masks indoors, and Los Angeles County health officials also “strongly” recommend this guidance.

Although the CDC or San Diego County officials do not recommend wearing masks, they are closely monitoring the spread of the variant.

“The delta variant is more contagious,” said Dr. William Tseng, head of vaccines at Kaiser Permanente in the San Diego area. “What does this mean? It may spread more easily and may make your condition worse. So, we must be careful of those who are not vaccinated.”

Although the variant is abundant in other parts of the United States, Tseng pointed out that the variant has not yet appeared in large numbers in San Diego, and only 25 cases have been reported this week. According to local health officials, 15 cases were reported last week.

Mr. Zeng is worried that the number of cases will continue to rise.

“If you want to take over here, it will take several months,” he said. “Enjoy time outdoors. Breathe fresh air. Try to stay away from crowded indoors. The most important thing is to get vaccinated.”

In addition, Big Bay Boom, which will be broadcast on FOX 5 this weekend, is expected to attract hundreds of thousands of viewers and bring 10 million U.S. dollars in growth to the local economy. For local businesses and suppliers like Eric Gomez, this is an excellent time.

“I think it is today,” Gomez said. “A good, big push that everyone is waiting for, do you know?”

He expects sunglasses sales this weekend to be as many as he has sold in a few months.

“It’s getting busier,” he said. “A lot of people are from Arizona and Vegas. Everyone is here today, but I think tomorrow and Sunday, especially Sunday will be our busiest.”
