JAIPUR: The wife of the Italian novel coronavirus patient undergoing treatment in Jaipur on Wednesday became Rajasthan’s second confirmed case of Covid-19 infection after the National Institute of Virology in Pune endorsed the preliminary diagnosis.The confirmation came even as health minister Raghu Sharma said that doctors at Jaipur’s SMS Medical College and Hospital were giving the woman’s 69-year-old husband, who is on a ventilator but stable, a combination of four drugs associated with the treatment of malaria , swine flu and HIV.“In the absence of a standard drug for the novel coronavirus, doctors can only respond to symptoms. We are administering Tamiflu (Oseltamivir), which is effective in the treatment of swine flu. We are also giving the patient Chloroquine, which is used on malaria patients, and two other drugs meant for treating HIV symptoms,” Sharma said.DS Meena, the medical superintendent of SMS Hospital , told TOI that the man’s wife was “fine” and responding to treatment. “Her husband’s condition has neither improved nor deteriorated. He remains on ventilator support.”An official bulletin issued by SMS hospital mentions that Rajasthan is still waiting for the drug remdesivir to be made available for therapeutic use on coronavirus patients.
