New test can diagnose mysterious infections

Researchers have created a brain test that can discover the source "of virtually any neurological infection," according to Scientific American.

For example, the test helped doctors to diagnose a brain tapeworm in a man from Nicaragua by identifying its DNA. The patient didn't have symptoms of the infection typically picked up by MRI scans.

How it works: Rather than look for a particular infection with a specific test, all of the DNA and RNA in a sample of cerebrospinal fluid is analyzed in order to identify foreign genetic material from viruses, bacteria, parasites or fungi. The challenge, researchers say, is "making sense of the output," but they've developed procedures for doctors to determine the most-likely cause of infection from the genomic data.

Coming soon: The researchers who developed the test at U.C. San Francisco will begin offering the test "as a custom-ordered service" to hospitals and labs across the U.S. on July 1.

Infant dies after testing positive for coronavirus in Chicago

An infant less than one year old died in Chicago, Illinois after testing positive for the novel coronavirus, the state health department said on Saturday.

Why it matters: The death would mark the first reported infant mortality from COVID-19 in the U.S. The fatality rate for the novel coronavirus in the U.S. is highest among those over 85 years old, per the CDC.

President Trump said on Saturday he is considering a "short term" quarantine of New York, New Jersey and parts of Connecticut — states that have already taken steps to quarantine residents and promote social distancing.

The big picture: With 112,000 people infected, the U.S. has the most COVID-19 cases in the world, exceeding China and Italy, per data from Johns Hopkins. A second wave of American cities, including Boston, Detroit, New Orleans and Philadelphia, are reporting influxes of cases.
