No more coronavirus cases in Vietnam have been detected during the past 12 hours after 11 cases were announced on July 27, according to the Ministry of Health in its July 28 morning update.

Doctors are closely monitoring newly confirmed cases at Da Nang Hospital, a coronavirus hotspot in central Vietnam. 

Two of the patients are in critical condition and they both are on ventilators due to respiratory failure, according doctors.   

In addition, one patient is undergoing the extracorporeal membrane oxygenation (ECMO), a life support machine.

Doctors are considering giving the ECMO therapy to the other patient who suffers hypertension and diabetes (type II).
