Say it quietly. An initial scan of overnight headlines features words like these: No spike; eases measures; two-month low; lowest since March 9; and reopen.

Sounds good, doesn't it? But best not to get too far ahead of ourselves.

With authorities still trying to get in front of COVID-19, there are more mysteries emerging over time.

For instance, eight more sailors aboard the USS Theodore Roosevelt have tested positive again for the coronavirus.

That takes the number to 13 for those who appear to have become infected a second time while serving aboard the sidelined aircraft carrier.

That some crew were testing positive again has puzzled officials and raised questions about reintegrating troops into the military if a second infection were possible.

Also questioned was the accuracy of testing itself. In some cases infection can be at such a low level that it is not detected by the test, which could mean there were no relapses. Also, people could be cleared though their virus levels were too low for detection.

Let the Washington Post introduce you to 12-year-old Juliet Daly.

Back in early April she was unwell, though with no COVID-19 symptoms, when her parents took her to the emergency department.

Turns out Juliet was in a kind of toxic shock, and her heart had become so inflamed it was barely beating.

She ended up surviving two heart attacks and any number of serious health conditions which doctors are linking them to coronavirus.

Doctors believe coronavirus infected her heart, and made its electrical signals go haywire and stop working.

British and Italian authorities issued alerts in April, and the American Heart Association warned last week that some pediatric patients "are becoming very ill extremely quickly," urging providers to evaluate them right away.

The Centers for Disease Control and Prevention in the US has named the condition - multisystem inflammatory syndrome in children, or MIS-C.

Writing in the Lancet medical journal last week, Italian doctors reported on a cluster of 10 children struck with the inflammatory condition in the coronavirus epicenter of Bergamo.

It is believed to be different from the illness first identified in Japan known as Kawasaki disease. It causes inflammation in blood vessels and includes a persistent fever. But these children - and Juliet - were older and they had more serious heart issues.

The mysteries deepen.
