On Friday, the CDPHE returned with a larger team to the site and tested 48 additional symptomatic workers, a spokesperson said in an email to Denver7 Friday evening. "The test results from samples collected today (July 12) are still pending," the spokesperson added, saying those samples will be tested this weekend.
--- previous post - - - At least according to twitter (which may or may not be correct) - the results for 48 of the 55 are not yet available, so only 4 people have had a negative test so far, and 5 have been positive.
-- 2nd edit - - Looks like you edited your previous post, where you claimed the 48 tested negative. Posting this here for completeness so that my post makes sense.
