Proper ventilation in workplaces key to preventing COVID infections

DAVAO CITY, Jan. 20 (PIA) - The city focal person on COVID-19 warned employers to be wary of proper ventilation in workplaces as a COVID-positive person needs only fifteen minutes to infect other individuals especially in airconditioned rooms and secluded areas.

Dr. Ashley Lopez, COVID-19 focal person in Davao City announced that 50 percent of the COVID-19 cases in the city are due to community transmission in the household with cases also rising particularly in the workplaces particularly in the call centers and banks.

He also noted the spike in COVID-19 cases in big companies in agriculture and government offices, but more in banks and business process outsourcing among the workplaces because of the use of air-conditioning system.

Lopez reiterated the implementation of the basic health protocols and other basic health standards in the workplaces to prevent the illness.

“We organize a team headed by Lorna Mandin of the Integrated Gender Development Division and Councilor Danilo Dayanghirang who are responsible of creating guidelines and process flow in following the mitigating measures inside the workplaces,” he said.

Lopez said that these teams monitor the compliance of health protocols inside the workplaces to ensure compliance and eventually rid the impact of the COVID-19 infection.

He said that aside from following the four main health protocols in the workplaces namely handwashing, wearing of face mask and face shield and social distancing, proper air ventilation must be observed.

“If you have no proper air flow in a closed-airconditioned room, there is the tendency that the air we breathe out recirculates longer within the area.  It is important that the air has entry and exit either through the window and the door,” he said.

Lopez said every one in the room has fifteen minutes in acquiring the COVID-19 from the COVID-19 positive individual.

As of January 19, 10,521 COVID-19 cases had been noted since March 2020 up to the present with 81 to 82 percent comprising the number of recoveries at 8,568 with 488 COVID-19 deaths.

Lopez said most of the COVID-19 cases belongs to asymptomatic and mild cases while only few are classified as critical and severe cases.

He said the accumulation of mild and asymptomatic cases are due to the contact tracing conducted by the city government while those who died were basically old with comorbidities and lingering illness.  (PIA XI-Joey Sem G. Dalumpines)
