The letter says the chance of the illness being COVID-19 is low but the care unit will be placed into lockdown as a precautionary measure.
"We cannot take the risk of an outbreak should the unthinkable happen," it says.
"Even if the results come back negative for COVID-19, we still need to shield the residents entrusted into our care against Influenza A and other respiratory illnesses.
"With the current situation, we are sincerely sorry to inform you that we will be placing the care unit under strict lockdown and that we will not be allowing visitors for the time being."
The village's apartments are currently unaffected.
