Half of US states are reporting increased Covid-19 cases and some leaders push new measures

“I have seen some things floating around about how we can’t enforce this because it’s an executive order,” the governor said. “They have the force of law [under] Kentucky statute.”

In New York, officials have reported several clusters of Covid-19 cases and the governor laid out a new plan this week on how the affected communities will move forward.

25 states report rise in cases

Kentucky and New York are among the 25 states reporting more new cases than the previous week.

Alaska and Montana reported record-high daily case counts this week. In Ohio, the governor said new cases are “trending upward.”

Fourteen states reported more than 1,000 new cases Tuesday. California, Florida, Kansas, Texas and Wisconsin had more than 2,000 infections.

Only three states — Hawaii, Iowa and South Carolina — report a decline in cases over the past week.

“Instead of going into the fall and the winter on a sharp decline down to a low baseline, we’re actually going into the fall and the winter with some parts of the country ticking up, which will ultimately lead to not only more infections, but more hospitalizations and then community spread, which will ultimately lead to morbidity and mortality,” Dr. Anthony Fauci told students at American University this week.

So far, more than 7.5 million infections have been reported — more than any other country. More than 211,000 Americans have died, according to Johns Hopkins University.

Neurological symptoms in hospitalized patients

Meanwhile, as health officials track the spread of the virus, many continue to research its effects on the body.

The study “highlights the high frequency and range of neurologic manifestations, which occurred in more than four fifths of Covid‐19 patients hospitalized in our hospital network system,” the researchers wrote in the study, published in the journal Annals of Clinical and Translational Neurology.

The researchers, from Northwestern University Feinberg School of Medicine, found that at any time during the course of their Covid-19 illness, 82% of the patients who were studied had neurological symptoms such as headaches or encephalopathy, altered brain function or structure.

Researchers found patients with any neurological symptoms tended to be younger than those without.

“The fact that any neurologic manifestations as a whole were more likely to occur in younger people is surprising, and could potentially be explained by greater clinical emphasis on the risk of respiratory failure than other symptoms in older patients,” the researchers wrote. “In contrast, encephalopathy was more frequent in older patients.”

Updated guidelines for vaccines

The US Food and Drug Administration issued guidance Tuesday for companies hoping to get emergency use authorization (EUA) for a Covid-19 vaccine.

The FDA said companies will have to include at least two months of follow-up after volunteers get their second dose of the vaccine. That would mean no company could seek an EUA before mid-November, because the vaccines furthest along in clinical trials — those made by Pfizer and Moderna — both require waiting either 21 or 28 days between doses.

“Being open and clear about the circumstances under which the issuance of an emergency use authorization for a COVID-19 vaccine would be appropriate is critical to building public confidence and ensuring the use of COVID-19 vaccines once available,” said Dr. Peter Marks, who directs the FDA’s Center for Biologics Evaluation and Research.

“I think comfortably around November or December, we’ll know whether or not the vaccine is safe and effective,” he said.
