Sir/madam.                                                                           I just want to know if a Catarct operation theatre is infected, and operation was done in that operation theatre itself for let suppose 22nd nov to 27th nov , and case of infection is seen in patients only operated on 22nd and not that to whole patients. Swab culture of operation theatre was taken on 30th. No operation was done betwen 28-30. So can we take coorelate result of swab report with infections caused in operation theatre??
