A disease expert has said that the recent outbreak of coronavirus has shown that people with no symptoms of the disease can still test positive.
It comes as public health officials prepare to issue further advice to prevent the spread of Covid-19 after they refused to rule out a regional lockdown in Kildare, Laois and Offaly.
The National Public Health Emergency Team (NPHET) is reviewing the surge in cases in the Midlands and they have advised anyone living in the area to pay particular attention to new symptoms.
The daily HSE update on Thursday included notification of five additional deaths and 69 new Covid-19 cases – bringing the total number of deaths in Ireland to 1,768, and the number of confirmed cases to 26,372.
Of the latest cases, 22 are in Offaly, 19 in Kildare, eight in Laois, six in Dublin and 14 are spread across eight other counties.
NPHET are now advising that everyone in Kildare, Laois and Offaly need to pay particular heed to any new #COVID19 symptoms such as cough, fever, shortness of breath or loss of taste/smell.— Department of Health (@roinnslainte) August 6, 2020
Self-isolate immediately and contact your GP if you feel unwell. Do not delay.
Paddy Mallon, a Professor of Microbial Diseases at UCD said the country has reached a “critical point”.
“The HSE has put a huge amount of work into creating a testing and contract using system,” he told RTE Radio One.
“What we’re seeing at the minute with the high rates of detection is actually that system working.
“We have colleagues in public health across the country that are working really day and night to try and keep on top of this. These outbreaks can be controlled.
“It’s a really simple message behind hand hygiene and around the wearing masks and the physical distancing, but also if you’re invited to get tested, get tested straightaway.
“It may be that people are sitting at home, they’ve been advised that they’ve been a close contact and they say I don’t have symptoms and don’t need to be tested.
“But data shows you do need to be tested, not so much because of the fact that you may not get sick but if you have the virus and you have no symptoms, you’re just as likely to have the same amount of virus, and have it for the same amount of time as someone who does have symptoms.
“So you’re just as infectious.
“The key is picking up people that have little or no symptoms, finding out that they have the virus, and isolating them is the key to really controlling this epidemic and stopping these outbreaks spreading into widespread community transmission which is a big concern.”

Acting chief medical officer Dr Ronan Glynn urged that those in Kildare, Laois and Offaly should pay particular attention if they have any coronavirus symptoms, and double down on health measures.
He said that there was a large number of cases notified to NPHET in these counties, which will be part of the new case numbers on Friday.
Meanwhile, chairman of the NPHET Epidemiological Modelling Advisory Group, Professor Philip Nolan, told the briefing that the reproduction number of the virus is now estimated to be 1.8.
