Covid-19 testing at airports could be piloted within three weeks as part of efforts to reduce quarantine times for travellers from overseas, Stormont’s chief scientific adviser said.
Professor Ian Young warned that a negative result upon arrival did not rule out someone recently infected developing the disease later. One option could be to repeat the test five to eight days hence.
He said: “While there has been significant public interest in a test at the airport being negative… that is simply not a safe approach. If the individual has become infected in the two or three days before returning to Northern Ireland then they could be carrying the virus but would test negative at the airport and would be provided with false reassurance and could go on to spread significantly.”
He is due to meet authorities in the rest of the UK next week to talk about pilot schemes.
“We have had ongoing discussions… about a pilot of airport testing of incoming travellers to estimate the infection.”
He hoped such an initiative would begin within the next three or four weeks but the issue was being led by UK-wide authorities.
Prof Young said the authorities could not make exceptions to the self-isolation rule for regions within countries on the watch list for high infection rates.
“We have had concerns that if we were to introduce regional differences for an overseas country it would be relatively easy for someone to get around those by travelling a short distance in the country concerned and returning to Northern Ireland or the UK via London or Dublin by a part of the country which was viewed as being safe.”
“It is very difficult to know exactly how incoming travellers have moved around in a country overseas with significant regional variation in prevalence.”
The public health expert said there had been some examples of the virus being contracted on an aeroplane but the number of cases had been consistently low.
The percentage of cases arriving in Northern Ireland associated with travel from outside the UK has also been low. SDLP South Down Assembly member Colin McGrath asked why countries which disclosed similar infection rates to Northern Ireland could not be exempted from the restrictions.
He said: “This has the effect of confounding the travel industry, which is almost on its knees. Businesses will be wiped out.”
He added: “Not everyone travels to lie on a beach for a fortnight. Many have family in different parts of the world and there are only so many months before Zoom meetings are not going to cut it.”
“That is where the qualitative element of decision-making comes in. We have to take account of the amount of testing being done in the other country and the trends in cases and come to the best estimate that we can.”
