The rate of positive coronavirus tests remains higher for Marylanders younger than 35 compared to Marylanders older than 35, according to data released by the state today.

Maryland health officials on Thursday began including a breakdown of positive testing rates among those two age ranges.

Starting March 29, the earliest date that the state has provided data on its seven-day average rates of positive tests, older Marylanders had a higher average positivity rate: 12 percent for Marylanders older than 35 and 9.56 percent for Marylanders younger than 35.

Both age groups’ positivity rates grew over the next three weeks, though the gap between the two groups widened.

The average positive test rate for older Marylanders peaked at 28.98 percent on April 17, while the positivity rate among younger Marylanders was 20.09 percent.

After that, older Marylanders’ rate of positive tests began to decline, while younger Marylanders’ positive test rate continued to rise.

Younger Marylanders surpassed the positive test rate of older Marylanders May 3, when 23.58 percent of coronavirus tests came back positive for people younger than 35. At that same time, 23.32 percent of coronavirus tests for people older than 35 came back positive.

Two days later, the positive test rate for younger Marylanders peaked at 24.4 percent on May 5. The average positivity rates of both age groups have trended downward since then, with people younger than 35 continuing to hold the higher percentage.

As of Wednesday, the seven-day average rate of positive tests sits at 5.55 percent for Marylanders younger than 35 and 3.27 percent for Marylanders older than 35.

For Marylanders overall, an average of 4.03 percent of test results reported over the past seven days has come back positive for COVID-19.

Maryland has completed a total of 1,348,880 coronavirus tests to date, with 16,699 test results reported in the past 24 hours.
