As Trump Praises Plasma, Researchers Struggle to Finish Critical Studies

Randomized trials outside the United States have not been able to prove plasma’s effectiveness, either. A trial at seven medical centers in Wuhan, the likely ground zero for the virus, concluded that convalescent plasma did not significantly improve patients’ recovery time.

Trump Administration Aims to Block New Funding for Coronavirus Testing and Tracing

The Trump administration has balked at providing billions of dollars to fund coronavirus testing and shore up federal health agencies as the virus surges across the country, complicating efforts to reach agreement on the next round of pandemic aid.

Senate Republicans had drafted a proposal that would allocate $25 billion in grants to states for conducting testing and contact tracing, as well as about $10 billion for the Centers for Disease Control and Prevention and about $15 billion for the National Institutes of Health, according to a person familiar with the tentative plans, who cautioned that the final dollar figures remained in flux. They had also proposed providing $5.5 billion to the State Department and $20 billion to the Pentagon to help counter the virus outbreak and potentially distribute a vaccine at home and abroad.

Federal Agency Halts Studies of Hydroxychloroquine, Drug Trump Promoted

The National Institutes of Health said Saturday that it had stopped two clinical trials of hydroxychloroquine, the malaria drug that President Trump promoted to treat and prevent the coronavirus, one because the drug was unlikely to be effective and the other because not enough patients signed up to participate.

The agency halted a trial that had aimed to enroll more than 500 patients after an independent oversight board determined that the drug did not appear to benefit hospitalized patients. The same day, the N.I.H. said it had closed another trial — of hydroxychloroquine and the antibiotic azithromycin — because only about 20 patients had enrolled in the planned study of 2,000 people.

The two trials the N.I.H. shut down represent the latest evidence that hydroxychloroquine has not lived up to its early promise of fighting the coronavirus.

The N.I.H. said Saturday that an independent oversight board that monitors safety met

Events Like Trump Rally Are ‘Perfect Storm’ for Viral Spread, Experts Say

The coronavirus won’t be loosening its grip on the United States any time soon, leading infectious disease experts said on Sunday. They are also uncertain how the viral spread will be affected by the patchwork of states reopening businesses and by large events like protests and President Trump’s upcoming campaign rallies.

“This virus is not going to rest” until it infects about 60 percent to 70 percent of the population, Dr. Michael T. Osterholm, the director of the Center for Infectious Disease Research and Policy at the University of Minnesota, said on “Fox News Sunday.”

Experts have estimated that without a vaccine, about 70 percent of the population will need to be infected and develop immunity in order to stop the virus’s spread, a concept called herd immunity. The number of confirmed American cases now exceeds 2 million, less than 1 percent of the U.S. population, according to the
