The doctors from Rajavithi Hospital in Bangkok said a new approach in coronavirus treatment had improved the condition of several patients under their care, including one 70-year-old Chinese woman from Wuhan who tested positive for the coronavirus for 10 days.

The drug treatment includes a mixture of anti-HIV drugs lopinavir and ritonavir, in combination with flu drug oseltamivir in large doses.

“This is not the cure, but the patient’s condition has vastly improved. From testing positive for 10 days under our care, after applying this combination of medicine the test result became negative within 48 hours,” Dr. Kriangska Atipornwanich, a lung specialist at Rajavithi, told reporters.
