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 straight away.
“One of the really noticeable things from the most recent outbreak is the number of people that are coming up positive that don’t have symptoms.
“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.”
