PETALING JAYA: Recent open visits may have contributed to a new Covid-19 cluster involving five cases in Selangor, says Health director-general Datuk Dr Noor Hisham Abdullah.
The index case was a patient from Labu Lanjut, Sepang, who was being treated for Acute Respiratory Infection (ARI) at Hospital Serdang on June 5 and found to have the virus.
