How UV-C disinfection devices have provided healthcare clients, staff & caregivers at the GGD in the Netherlands with peace of mind for more than 10 years.
As the world moves through a fourth wave of COVID-19 infections, healthcare agencies continue to look for ways to protect the public from current and future threats. On the long term, we need measures that go beyond the first-tier protection provided by individual actions like social distancing and face masks.
UV-C disinfection lighting1 has been around for more than 80 years, playing a crucial role in minimizing the threat of a variety of harmful pathogens. More recently, it has added an important layer of protection against COVID-19 in workplaces, schools, and public and private buildings.

In the Netherlands, GGD agencies provide public health services in 25 regions across the country. Their tasks range from preventative healthcare programs to travel medicine and most recently, COVID-19 testing and vaccination programs. UV-C disinfection upper air luminaires have been in place at GGD facilities for more than ten years, initially to provide clients and staff with additional protection against the spread of tuberculosis (TB). Like COVID-19, TB is spread through highly infectious airborne pathogens, but in this case, the disease is spread by bacteria instead of a virus. In both cases, UV-C disinfection upper air devices are an effective solution since they have been proven to counter the spread of all viruses and bacteria tested to date.3
While protecting staff against potential infections is important to the GGD, so is to make clients feel safe at their locations.
“Some of our clients are hesitant to come in as they’re afraid of getting infected by harmful viruses or bacteria during their visit,” said Liesbeth Huizer, a Medical-technical employee who has been working at the GGD in Rotterdam for more than 40 years.
According to Huizer, having UV-C really helps in providing clients with peace of mind. “Explaining to them that we have UV-C upper air luminaires installed on our ceilings really helps reassure them,” she said.
"The system is so easy to install, and it doesn’t make any noise nor causes dry air or draft. The bluish glow really provides people the assurance that it is working. I’m surprised that even 1.5 years into this pandemic, we’re not making broader use of a technology that we have been using for 20 years and which has proven itself against TB and SARS CoV-2. It’s such an obvious measure.”
“UV-C is a very common measure for TB infection control. We have been using UV-C devices to our full satisfaction at various locations for over 20 years,” adds Elske Beintema, Team manager of GGD Brabant-Zuidoost located in Eindhoven. “As maintenance and replacement of devices is part of the agreement we have, for us it is a very stable and reliable technology.”

Across the border in Belgium, Technical Director Jacky Fafchamps at the University Medical Center St. Pierre in Brussels explains that the hospital recently extended the use of UV-C disinfection upper air devices to the Emergency departments for children and adults. UV-C devices are installed in locations including the isolation department for other infectious diseases, Radiology, Pulmonology and Lung Function.
“We have been using UV-C disinfection upper air luminaires for over ten years,” said Jacky Fafchamps. “We started using this after our Chief Medical Officer for infectious diseases read the scientific literature. We’re very happy with the additional layer of protection that this provides to our visitors and staff and recently decided to install more UV-C disinfection upper air devices.”
It’s clear there is still work to be done both to curtail the spread of the current pandemic and to safeguard public health in future. With key health services in the Netherlands and Belgium convinced of the effectiveness of UV-C disinfection, it’s clear that opportunities exist to implement this technology more broadly.

1 UV-C light is a powerful disinfectant with an impressive track record in breaking down the DNA and RNA of viruses and bacteria, according to Malayeri et al. Fluence (UV Dose) Required to Achieve Incremental Log Inactivation of Bacteria, Protozoa, Viruses and Algae, 2016
Research conducted at the National Emerging Infectious Diseases Laboratories (NEIDL) at Boston University proved the effectiveness of Signify’s UV-C light sources in inactivating SARS-CoV-2, the virus causing COVID-19, on surfaces, states Nadia Storm et al., Rapid and complete inactivation of SARS-CoV-2 by ultraviolet-C irradiation, 2020. The UV-C irradiance used in this study was 0.849 mW/cm2.
Further research by NEIDL into their effectiveness revealed that the UK Kent and South African variants of the virus were also susceptible to inactivation by UV-C light. This bodes well for hopes that it will effectively inactivate future variants of the virus.
