He says frontline security staff are encountering visitors wanting to flout the mask-wearing regulations and becoming abusive when asked to wear a mask.
"They then enter the hospital with a mask to comply and take off their masks as they enter the wards and visit patients which is putting our patients and staff at serious risk of contracting viruses such as Covid-19 and influenza."
Dr Simmons says the result is enforcing a no-mask no-entry policy unless visitors have proof of a legitimate mask exemption.
"However, anyone who is unwell will not be able to enter as part of our infection control measures."
Matt Green, healthcare security operations manager for Te Whatu Ora Taranaki, says if visitors remove their masks while visiting patients, they will be asked by ward staff to put their masks back on.
"If the visitor refuses to put their mask back on, ward staff will call security and security and we will be asking them to leave the hospital."
Dr Simmons says with rapidly increasing numbers of covid-19 and Influenza cases in the Taranaki community, Taranaki Base and Hāwera Hospitals have also introduced a restricted visitor policy.
"The policy means there is only one visitor per patient at a time, no visitors under 16 years of age unless with a prior appointment, and no admittance of visitors if they are unwell."
He says there will be exceptions on compassionate grounds case by case for maternity and the children's ward.
"For example, where parents and support people may be required. We will also take into consideration support for palliative patients, and ward managers and/or lead clinicians may approve other exceptions based on other compassionate grounds."
The visitor restrictions are due to steadily rising Covid-19, influenza and RSV transmission as well as gastroenteritis cases in the community.
"The Taranaki community can play a key role in easing the pressure on the region's hospitals by getting vaccinated, getting a RAT test if symptoms appear, and staying home if you feel unwell. The other mainstay of preventing the spread of respiratory infection by good personal hygiene such as regular hand washing, using alcohol-based hand gels, coughing or sneezing into your elbow, wearing masks where necessary and social distancing, which cannot be overstated," says Simmons.
