Fianna Fáil leader Micheál Martin has called for greater transparency around the clusters of coronavirus cases.
He said: "Currently, I think there should be greater transparency where outbreaks happen and where clusters happen because when rumours develop, it is more constructive behaviour in my view than stating it as it is.
"I'm aware of some areas where people have contacted me about outbreaks in particular areas and that's causing a lot of concern and I'll be asking for greater transparency so people are aware."
He also called for greater restrictions to be enforced to help tackle the coronavirus outbreak.
Mr Martin said that while most people are adhering to the social distancing guidelines, others are failing to do so.
"I think most people in the country that I have observed have been adhering to the guidelines that have been issued - there are very few people on the streets," he said.
He said there is evidence of mass gatherings, including people queuing for chips.
I think severe restrictions are required in terms of public gatherings as it's all about protecting our senior citizens and protecting people with underlying conditions," he said.
"So whatever it takes to protect those who are most vulnerable from this virus, then that has to be taken subject to the public health advice that we will be receiving later."
