Veterans Affairs Secretary Robert Wilkie said in a letter on Wednesday that veterans are being treated for the novel coronavirus with hydroxychloroquine only when patients and their doctors find it medically necessary.

Why it matters: The Food and Drug Administration warned doctors last week about prescribing the antimalarial drug to COVID-19 patients as it appears to be causing some serious and potentially life-threatening side effects.

  • An independent analysis of veterans hospitalized at VA facilities, which has not yet been peer-reviewed, found an increased risk of death associated with coronavirus patients who were only treated with the antimalarial drug.
  • The study is the largest examination to date of how the drug interacts with coronavirus patients, AP reports.

Details: The analysis, conducted by university researchers with VA approval, retrospectively looked through medical records of 368 male veterans, with a median age of 58, who were hospitalized with COVID-19 March 11 to April 11, per the study and Wilkie's letter.

What they're saying: "The Veterans who received hydroxychloroquine were at highest risk prior to receiving the medication," Wilkie wrote on Wednesday, adding that the VA is adhering to FDA guidance for the drug's use.

  • Wilkie declined to say in a call with major veterans organizations on Wednesday whether the agency had issued guidance to patients and doctors on the use of hydroxychloroquine, as well as how widely the drug is used, AP reports.
  • The VA told AP that it "permits use of the drug after ensuring veterans and caretakers are aware of potential risks associated with it, as we do with any other drug or treatment.”

New Zealand now has active no coronavirus cases in the community after the final six people linked to the Auckland cluster recovered, the country's Health Ministry confirmed in an email Wednesday.

The big picture: The country's second outbreak won't officially be declared closed until there have been "no new cases for two incubation periods," the ministry said. Auckland will join the rest of NZ in enjoying no domestic restrictions from late Wednesday, Prime Minister Jacinda Ardern said, declaring that NZ had "beat the virus again."

Massachusetts Gov. Charlie Baker announced Friday that the state's second phase of reopening is "postponed indefinitely" in response to a modest increase in coronavirus cases.

The big picture: The state is reporting more COVID-19 deaths than most others across the U.S. outside of domestic epicenters like California, or previous hotspots including New Jersey and New York, per a New York Times database.

African countries collectively surpassed 1 million confirmed coronavirus cases this week, according to Johns Hopkins University data.

Why it matters: Some health experts believe that the true number of COVID-19 cases among African countries is higher than that figure due to a lack of testing, and fear that undetected cases could overload some of the world’s weakest health systems, according to AP.
