Irish guests are among those who are in official quarantine at a hotel in Tenerife after four people tested positive for the coronavirus.
The hotel was put on lockdown on Tuesday after an Italian doctor and his wife staying at the H10 Adeje Palace hotel tested positive for the disease.
They are currently in quarantine at a Tenerife hospital.
According to health authorities on the Canary Islands, two other Italians who were part of the same group of holidaymakers at the hotel have also tested positive.
However, 130 guests out of the 700 on lockdown have been allowed to leave as they arrived after the Italian doctor had left the hotel but before the lockdown began.
While it is thought that up to 20 guests who were on lockdown are Irish, it is not known if any of the people who have been allowed to leave are Irish.
"We've been told officially that we're here until Monday, March 8th," an Irish guest from within the hotel told the Herald. March 8 will mark 14 days since the Italian doctor left the hotel - but if anybody develops symptoms before then, the guests may be detained for longer.
"Nobody else apparently in the hotel has shown any symptoms yet, but the concern is that if somebody were to get the virus in the hotel, the clock would reset at 14 days then," the guest said.
Meanwhile, actress Aoibhin Garrihy revealed she had a lucky escape from Tenerife last weekend after having her first family holiday away with her husband and their two little girls.
The family narrowly avoided the outbreak of the coronavirus on the holiday island. "We went to Tenerife and we got out of there just in time," she said.
"Thank God we got out in time. We got home on the Saturday last but it's very scary what's happening."
Meanwhile, the Department of Foreign Affairs and Trade's dedicated hotline for citizens with coronavirus-related concerns has received approximately 500 calls per day over the past two days.
The line, which opened on Tuesday, operates daily from 8am to 8pm and is managed by its consular unit and volunteers from across the department.
"We have provided updates today for over 25 countries," a department spokesman said.
"These are mostly minor updates to reflect local developments in each country and, in some cases, to add general health advice."
