With numbers spiking across Southern states, the United States set a daily record for new COVID-19 cases Thursday in a return to figures not seen since late April. According to data collected by Johns Hopkins University & Medicine Coronavirus Resource Center, 40,401 new cases were recorded June 25, surpassing the previous record set April 24, which saw 36,291 new cases.

Record Virus Cases in U.S. Defy States’ Efforts at Control – Bloomberg

U.S. governors are reversing plans to reopen their states as the country registered the biggest-ever jump in coronavirus cases, in a growing recognition that the contagion is increasingly dictating events in much of America.

Dr. Fauci announces a new testing strategy for coronavirus – Washington Post

The approach works this way: Samples from, say, 20 people are combined into a single pool. One coronavirus test is used on the entire pool. If the test comes back negative, researchers know they can move on to another pool of samples. If it comes back positive, only then would each individual be tested. “What you need to do is find the penetration of infected people in your society,” Fauci said. “And the only way you know that is by casting a broad net.”

A Devastating New Stage of the Pandemic – The Atlantic

For the past few weeks in the United States, the awful logic of the coronavirus seemed to have lifted. Stores and restaurants reopened. Protesters flocked to the streets. Some people resumed going about their daily lives, and while many wore face masks, many others did not. Yet cases continued to ebb. Even though the U.S. had adopted neither the stringent lockdowns nor the trace-and-isolate strategies seen in other countries, its number of confirmed COVID-19 cases settled into a slow decline. Last week, Vice President Mike Pence bragged that the country had made “great progress” against the disease, highlighting that the average number of new cases each day had dropped to 25,000 in May, and 20,000 so far in June.

Latin America’s coronavirus crisis is only getting worse – Washington Post

In many parts of the world, authorities and experts are fretting over the onset of a coronavirus second wave. Yet in the Americas, there’s still no end in sight to the first. The virus is surging in various U.S. states, and the American death toll has eclipsed 120,000. On Thursday, the head of the Centers for Disease Control and Prevention said the real number of infected Americans is probably 10 times the 2.3 million official count.

Bloomberg COVID Podcast: What Happened in Houston

In Houston, Texas, new Covid-19 cases and hospitalizations are surging. Some experts expect the virus outbreak to swamp the city’s medical infrastructure by July 4th. Emma Court and Joe Carroll report that if cases keep rising at their current pace in Harris County, which includes Houston, they will triple or quadruple by mid-July. The city’s hospital system may not be able to manage the crisis.

Strokes, Altered Mental States Seen in Some Acute Covid Patients – Bloomberg

Strokes were reported in more than 60% of 125 patients in a U.K.-wide study who suffered brain problems along with Covid-19, according to research published Thursday in the Lancet Psychiatry journal. Almost a third experienced signs of confusion or changes in behavior reflecting an altered mental state. The study focused on cases that were serious enough to require hospitalization.

It’s not just the lungs: The Covid-19 virus attacks like no other ‘respiratory’ infection – STAT

The reports seemed to take doctors by surprise: The “respiratory” virus that causes Covid-19 made some patients nauseous. It left others unable to smell. In some, it caused acute kidney injury.

SARS-CoV-2 can replicate in human pediatric gastric organoids – MedicalNews.Net

A diverse research group from the United Kingdom, Italy, China, and Australia established a first expandable human gastric organoid culture across fetal developmental stages, supporting the hypothesis that fetal tissue seems to be much less susceptible to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection – especially in the early stages of development.

Ensuring Uptake of Vaccines against SARS-CoV-2 – NEJM

s Covid-19 continues to exact a heavy toll, development of a vaccine appears the most promising means of restoring normalcy to civil life. Perhaps no scientific breakthrough is more eagerly anticipated. But bringing a vaccine to market is only half the challenge; also critical is ensuring a high enough vaccination rate to achieve herd immunity. Concerningly, a recent poll found that only 49% of Americans planned to get vaccinated against SARS-CoV-2.1 One option for increasing vaccine uptake is to require it. Mandatory vaccination has proven effective in ensuring high childhood immunization rates in many high-income countries. However, except for influenza vaccination of health care workers, mandates have not been widely used for adults.

Does air conditioning spread the coronavirus? – NBC

Experts say there’s little evidence to link air conditioning to the spread of the coronavirus. Rather, the risk more likely comes from the amount of time spent indoors in close proximity to others. A CDC study raised concerns that air conditioning could spread the coronavirus. The research detailed an instance in which 10 restaurantgoers in China were sickened after eating at neighboring tables. The authors concluded that the virus was spread by the air conditioning system blowing tiny virus-laden droplets through the air. [Related CDC Study]

Wearing A Mask Is A Sign Of Mutual Respect During The Coronavirus Pandemic – Forbes

As we continue to struggle with the realities of living through the Covid-19 pandemic, I can’t help but feel disappointment, even sadness, every time I venture out of my house and witness people not wearing a mask. My rationing of groceries and household goods intended to keep me home for three weeks at a time have depleted several times over as the pandemic nears its five month mark in the United States. Putting on my mask, and gloves, to head to the corner market or get a ”breath of fresh air,“ I am astounded by the large numbers of people who are not wearing a mask.

Personal Protective Equipment and Covid-19 – NEJM

The routes of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (Covid-19), include direct contact and indirect contact. More importantly, SARS-CoV-2 may maintain its biologic stability in aerosol and on different surfaces for hours to days.2 In the care of patients with infectious viruses such as Ebola, a principle of protection for staff wearing personal protective equipment (PPE) is to not expose their skin.
