A made-in-Vietnam supervision system for quarantined people and Covid-19 patients has been invented by ND Technology Research and Development Joint Stock Company (ND Tech).
According to Director of ND Tech Ho Van Tha, the system helps health workers easily track people leaving the quarantine center without authorization, automatically and promptly notify management agencies if someone in the center violates the Covid-19 prevention regulations.
The system also manages unlimited data, which is very easy to query and supervise quarantined people and helps reduce costs in terms of time and movement of managers during the tracing process, especially reducing management and equipment costs.
"It is integrated with GPS. The quarantined persons must install the isolation application on their smartphones and turn on the GPS mode. The system will warn when such persons leave the isolation area with the phone, turning it off or turning off the GPS mode," Tha said.
Besides phone applications, the system also uses a safety bracelet. Quarantined persons must install the application, turn on GPS mode and wear a safety bracelet on their hands. The bracelets are water-resistant, compact, and have good battery life for the isolation period.
The system will warn when the bracelet loses connection with the phone (being taken off, or away from the phone).
Than said that with the price of US$7-10, the Vietnamese supervision system is cheaper than the one produced in foreign countries. A similar system made in South Korea is priced at US$20.

Than said that the evolution of the Covid-19 pandemic is increasingly serious in many provinces and cities across the country. The rising number of people in concentrated quarantine centers is making it more difficult for management agencies to look up information of isolated people for epidemiological investigation.
The system has already been deployed in some localities in Vietnam.
Over two months into its fourth wave, the most challenging ever that Vietnam has encountered, the country has recorded 14,505 cases in 51 cities and provinces. Bac Giang still leads the case count with 5,709 infections, followed by Ho Chi Minh City with 4,573.
The country has vaccinated around 3.6 million people, including over 204,000 fully inoculated with two shots.
