After a lull, the swine flu menace has reared its ugly head in Mumbai. BMC official reported two positive swine flu cases on Monday. One of the patients is a 34-year-old man from Mankhurd. He is being treated at the civic run Kasturba Hospital near Chinchpokli. The other patient is a 35- year woman from Malad. “The Malad patient is under treatment from a private practitioner at home,” said Dr Mangala Gomare, who heads the civic epidemiology cell. It’s not clear whether they got the virus from Pune or Mumbai.
