According to Saturday morning John Hopkins Covid-19 tracking, approximately 5.3 percent of U.S. cases have resulted in death over the course of about six months. Contrastingly, the deadliest flu year in the U.S. over the past five reporting years was in 2014-2015 when 51,000 people died as a result of 30 million cases, which represented an estimated .17 percent of the total case count over the one-year period.  

The U.S. mortality rate holds up when looking at the number of cases and deaths reported globally, though it is substantially lower or higher than other countries when compared side-by-side. For example, John Hopkins finds the mortality rate in Italy is as high as 14.5 percent, whereas India is reporting a much smaller 3.3 percent. 

A virus that on average is 5.1 percent more deadly than the common flu is a reality leaders are forced to consider as they weigh policies to protect the populace against the need to reopen economies and allow regular activities. In the U.S., the president has chosen to hold an indoor rally in a city plagued by a sudden rise in cases.

All eyes are on Tulsa, Oklahoma Saturday as the location of the first in-person presidential campaign rally since the pandemic took hold in the U.S. The Trump-Pence 2020 campaign expected to fill the 19,000-seat BOK Center with supporters who were required to sign a release of liability protecting the campaign from lawsuits in the event people contract Covid-19 as a result. 

The campaign offered masks inside the event center but did not require they be worn, and physical distancing was not observed inside or outside the arena.

As campaign staff prepared for the massive event, six of whom contracted the virus while visiting Tulsa ahead of the weekend, the city is struggling to keep up with a rise in Covid-19 cases and hospitalizations. 

During the Saturday rally, Trump suggested we “slow the testing down” and referred to the 2019 novel coronavirus as the “Kung Flu.”

According to the Oklahoma State Department of Health, the city of Tulsa is reporting the second highest number of confirmed cases in the state, second only to Oklahoma City as of Saturday.  

The Tulsa County Health Department reported 136 new cases just between Thursday and Friday — the total number of cumulative cases has more than doubled in the 14-day period between June 5 and Friday.

The state experienced a spike in cases over the past week, with 4,224 cases reported just Wednesday, which was the highest one-day change since the pandemic began. Another 3,893 additional confirmed infections were reported Friday. California’s case mortality rate as of Friday is 3.1 percent.  

Alameda County

  • Confirmed Cases: 4,805
  • Deaths: 118

Source: Alameda County Public Health Department as of Saturday with data reported through Friday.

Alameda County’s calculated Covid-19 case mortality rate is 2.4 percent, according to county data through Friday. Even as the area launches further into reopening plans, the number of new cases reported daily remains alarmingly high. Preliminary data, subject to increase, reflects an additional 105 confirmed cases reported just Friday. 

Data broken down by ethnic and racial groups paints a picture of enormous disparity. While the case mortality rate for the African American/black population is only .6 percent higher than the 6.3 percent experienced among white people in Alameda County, black members of the community are being disproportionately impacted.

Representing 22 percent of the county’s overall death toll is a far stretch from the 7.9 percent black residents contribute to the total confirmed case count. 

Oakland alone accounts for nearly 40 percent of all countywide cases. 

The county’s reopening plan was recently updated, permitting more outdoor businesses and activities to resume Friday. The new order allows indoor retail, including malls.

The Acts of Full Gospel Church of Oakland in partnership with Bishop Bob Jackson will host a free drive-through Covid-19 antibody test site at the church parking lot Tuesday from 1 p.m. to 5 p.m.. The church is located at 1034 66th Ave. The one-day site aims to serve uninsured and underserved members of the Oakland community.   

Contra Costa County

Despite a much lower number of confirmed cases than is seen in Alameda County, Contra Costa County’s case mortality rate is slightly higher, with 2.5 percent resulting in death. Ninety-three new cases were reported Friday, which is the highest number of cases added in one day since pandemic tracking in the area began. For context, the second highest one-day change was recorded on June 8, with 68 new cases. 

Still, officials have not revised the county’s aggressive reopening plan.

Hair salons and barber shops, as well as indoor religious services — with modifications for distancing — reopened throughout the county Wednesday.

Health officials announced Friday the introduction of “social bubbles,” which will permit small, limited gatherings. According to the statement, a social bubble is defined as:

“(A) stable group of 12 people or less who have collectively agreed to limit their in-person social activities to only each other for at least three weeks. Individuals belong to only one social bubble at a time, except for children who may belong to a second bubble related to a childcare or camp environment. Children living in two different households may participate with both parent’s social bubbles, so they do not have to choose between them.”

According to Saturday’s data, the county’s case mortality rate is just a little more than 1.7 percent.

Health officials issued detailed guidelines for home isolation and home quarantine expectations. The directives require all persons diagnosed with Covid-19 and those likely to have contracted the virus to self-isolate, and further mandates anyone who has come in close contact with an infected individual to quarantine at home for 14 days. The county has published extensive information for both requirements, which can be accessed here

The county also revised its shelter-at-home order effective Friday, which incorporates the statewide face mask/cloth covering mandate while allowing movie theaters, nail salons, massage therapists, indoor gyms and indoor pools to reopen. 

The area’s low death count related to Covid-19 has maintained throughout the pandemic, contributing to the 1.8 percent case mortality rate.

Mayor London Breed Friday announced that more than $1 million has been set aside to lend to black business owners who have been impacted by the pandemic. The African American Small Business Revolving Loan Fund was made possible by individual and organizational donations through Give2SF.  

Unlike its East Bay neighbors, San Francisco’s number of new cases has maintained a steady decline. County health officials are reporting a seven-day average of 19 new cases per day. Hospitalization rates have also improved substantially with only 31 Covid-19 hospital patients reported as of Thursday — that’s the lowest hospitalization rate the area has seen since March 30.

The 1.5 percent case mortality rate in the area is remarkably low, especially considering population density in The City and county.

This is the third such site created in the city to accommodate homeless individuals and provide physical distancing space during the Covid-19 pandemic.

The latest health department reporting indicates that 1,450 hotel units and 98 RV units are currently occupied by people deemed to be part of “vulnerable populations.” The Board of Supervisors had passed a resolution requiring city officials to acquire 8,250 hotel rooms for use in housing unsheltered individuals and first responders. A total of 2,532 units (hotels rooms and RVs) have been acquired to date.

When compared to the other eight counties in the greater Bay Area, and especially to Solano County, which is very similar in cumulative case count, Sonoma County’s .5 percent case mortality rate is notably low. 

The area’s ability to mitigate the virus spread is even more impressive when considering that people aged 65 years or older make up nearly a fifth of the county’s population, according to county data.
