South Florida COVID-19 numbers surge, pushing positivity rates above 5%

New COVID-19 numbers show South Florida is experiencing a significant uptick in cases, far greater than the rise seen in the previous few weeks.

As Florida Politics reported earlier this week, Miami-Dade, Broward and Palm Beach counties had each seen their case positivity rates rise over the previous 2-3 weeks. Still, case numbers had not neared the levels seen prior to the widespread availability of the COVID-19 vaccines.

But the newest Department of Health report is the largest week-to-week rise in cases since early June. The recent increases could cause concern, particularly in Palm Beach County.

Palm Beach’s positivity rate jumped from 4.3% in the period covering June 25-July 1 to 6.9% from July 2-8. That’s a whopping 2.3 percentage points in just one week. Miami-Dade’s case positivity rate jumped 1.7 points, while Broward’s rose by 1.6 points.

Miami-Dade’s one-week positivity rate now sits at 5.3%. That’s the highest number seen since the week covering April 28-May 4 — more than two months ago. Broward’s positivity rate for the previous week is 5.5%, also the highest seen since the week of April 28.

But Palm Beach’s positivity rate of 6.9% is the worst that county has seen since mid-February — nearly five months ago, when vaccine availability was still highly restricted. State data shows 62% of those aged 12 and older have been vaccinated in Palm Beach now, yet the virus is spreading as it did early on in the vaccine push.

Two contributing factors to the rise are the decreasing rate of vaccinations in all three counties along with the increasing prevalence of the more transmissible COVID-19 delta variant. The Joe Biden administration has advocated for unvaccinated Americans to get their shots as the delta variant spreads. South Florida’s surging numbers appear to be a sign that concern is warranted.

Palm Beach also notably has the lowest share of its 12 and older population vaccinated out of the three major South Florida counties. Broward’s number sits at 66%, while that number is 73% in Miami-Dade.

The newest case numbers across South Florida likely do not fully factor in recent July 4 celebrations. And with each county remaining on an upward trajectory, it’s unclear how high the numbers could rise before plateauing.

Here are some of the weekly numbers for the previous three weeks throughout the South Florida tri-county area:
