The county has seen large daily increases consistently in the last week since the start of the pandemic. The second largest spike was on June 16 with 436 new cases in one day, followed by 412 cases on Friday and 408 cases on Thursday.

Individuals between the ages of 20 and 29 make up the largest age group of infected persons with more than a quarter of the total cases.

“Don’t use the state’s reopening plan as an excuse to throw house parties or hold extensive gatherings,” Mayor Ron Nirenberg said in a tweet. “We have yet to discover a COVID-19 cure or vaccine. Wearing a mask seems so simple, but it can save lives.”

Here are five numbers that detail Bexar County's rise in coronavirus cases:

2,700: Almost half of the positive cases — nearly 2,700 — have been attributed to close contact as of Sunday night, Metropolitan Health reported.

406: The number of patients with COVID-19 in area hospitals as Sunday evening, according to Metro Health. That is more than four times as many as on June 1, when hospitals were treating 93 coronavirus patients.

Officials at UT Health San Antonio said their computer models suggest that the number of coronavirus patients in the hospitals could nearly double in the next two weeks and continue to increase until August.

64: The number of patients on ventilators, compared with 49 on Saturday. On June 1, there were 20.

1,000: Early in the pandemic, it took more than a month for Bexar County to break 1,000 cases. Earlier this month — from June 12 to 17 — it took only five days.

133: The number of patients in intensive care as of June 21 was 133, up from 39 at the beginning of the month.
