Lords ChamberTo ask Her Majesty’s Government what is their strategy for protecting UK citizens from the threat posed by the spread of Wuhan novel coronavirus (WN-CoV).
My Lords, we are monitoring closely the development of this virus. Advice from Public Health England and the Chief Medical Officer is that the risk to the UK is currently low. The UK is well prepared for the emergence of novel viruses. As part of our preparedness, we have introduced enhanced monitoring of direct flights from Wuhan to the UK and updated our travel advice for Wuhan. We continue to update health workers on how to identify, treat and contain any possible cases.
My Lords, I thank the noble Baroness for her reply and commend the Government for publishing tomorrow initial measures for controlling the spread of this virus, if it comes to the United Kingdom. This is a newly identified virus, which probably originated in animals, particularly in the seafood markets in Wuhan. None the less, it is 80% genetically identical to the SARS virus, which killed a significant number of people. We now understand that, although the Chinese have sequenced the genome of the virus, it has mutated and can now spread directly from human to human, which raises the likelihood that it will spread more widely. The initial illness can vary and is sometimes very mild, hence the case in the United States where the diagnosis was not made on arrival at the airport in Seattle by the authorities, even though they had procedures in place. Will the Government keep a watch out and update the advice depending on how the virus develops? Secondly, will there be procedures for quarantine and follow-up contact if a case is identified, particularly if the virus mutates and becomes highly virulent?
I thank the noble Lord for his important and timely Question. I am happy to update the House that, from today, enhanced monitoring is in place for all direct flights from Wuhan to the UK. Public health officials will meet every direct flight from Wuhan to the UK and will be on hand to provide information about symptoms. Mandarin and Cantonese speakers will be on hand and leaflets will be available in several languages. We will also roll out enhanced monitoring of all flights arriving in the UK from China. Leaflets and information will be available across all UK airports, advising travellers from China on what to do if they feel unwell. The enhanced monitoring of direct flights will obviously be kept under continuous review and expanded if necessary. The risk to the public is low and the NHS is well prepared but, to answer the noble Lord, any patients assessed for this new disease would be isolated under standard procedures if necessary. There are a number of infectious disease units around the country that would be able to respond appropriately.
My Lords, it is good that the Chinese Government, and indeed our Government, are responding better than has perhaps happened in some past incidents, including over SARS. The BBC has reported today that a number of Chinese cities are now reporting that there are people with this condition. When will flights from those cities, and not just Wuhan, be monitored? Also, will there be specific traveller advice for UK citizens travelling into China who have chronic and underlying conditions that mean they may need to take more care?
I have a list of the current confirmed cases, which I am happy to place in the Library—it is probably not constructive to read it out—although the numbers are changing regularly. We are keeping travel advice and the monitoring of flights in and out of other Chinese cities under constant review. The advice at the moment is against all but essential travel to Wuhan. We will keep travel to other Chinese cities under close consideration.
My Lords, does my noble friend agree with one of the precepts of Darwinian medicine that there is generally a trade-off between virulence and contagiousness and that, in the world of viruses, if you want to spread by casual contact, it tends to help to keep the patient healthy and standing on their feet—as indeed I am with a cold at the moment? If this virus does spread from man to man—sorry, person to person—there is a chance that it may reduce in virulence and it is, therefore, important to keep in perspective the warnings that we give people. While we must not underreact to this, it is also important that we do not overreact and cause major disruption to the economy, as has occasionally happened with responses to previous incidences of influenza.
That was well put. Our view is that this is a proportionate and sensible response that is scalable and appropriate according to the evidence available. We will obviously be reviewing what is a new and emerging infection. Scientific understanding of the disease is evolving rapidly—essentially on a daily basis. We will obviously review the measures set out regularly.
It is important to set out what the symptoms are, in case anybody listening needs to understand. This is essentially a bad respiratory tract infection that could turn into pneumonia. At this stage around 2% of known cases have died. To compare mortality rates, SARS had one of 10% and Ebola 70%. That gives a level of perspective, but the picture is evolving and we will keep this under close review as the situation develops. Unsurprisingly, of course, within that context those at greatest risk are the vulnerable, the elderly or those with underlying health conditions, so the advice is to come forward if such symptoms occur.
Notwithstanding the noble Baroness’s remarks, I am pleased and reassured that the Government have implemented the measures outlined and welcome the precautionary approach taken to the arrival of passengers from the Wuhan region of China. Can she confirm that the Government have assessed whether adequate resources are available in the PHE port health teams to carry out screening procedures and any further screening procedures that might be necessary?
We have indeed. First, three direct flights from Wuhan arrive into Heathrow and a team of public health experts, which will include the principal port medical inspector, the port health doctor, the administrative support and team leader and a translator, will meet every direct flight from Wuhan. We believe that this is a scalable solution, which could respond to a developing health challenge. In addition, before a flight lands a message will be broadcast to passengers in several languages to encourage them to report illnesses to flight staff and the captain will be required to provide an early warning of any illnesses on the aircraft one hour before arrival, which allows a much more appropriate response on landing. We believe that this is a manageable and effective response. The NHS has a very good record of responding to similar situations, whether with Ebola or monkeypox. We can be very proud of our public health record in these areas and can be confident in how bodies will respond to this incident.
My Lords, does the Minister agree that this has come at a very difficult time, because we are the middle of the flu season and this is difficult to diagnose? Does she realise that 15 health workers have been diagnosed in China? Therefore, will all health bodies be told to be aware?
The noble Baroness is absolutely right: there is great pressure on the NHS and we need to make sure that the appropriate information is given to the system so that there is no undue anxiety in that regard. As I said, the NHS has a tremendous record in responding to similar incidents. Clinicians in primary and secondary care have already received advice covering initial detection, investigation of possible cases, infection prevention and control and clinical diagnostics. NHS England and NHS Improvement have developed an algorithm to support NHS 111 to identify suspected cases and a central alerting system alert will be issued to the front line by the Chief Medical Officer, the medical director of Public Health England and the medical director of NHSE and NHSI to increase awareness of the situation and actions if potential cases present.
As I said to the noble Lord, Lord Patel, there are a number of infectious disease units around the country that can take suspected patients and are accustomed to responding in this way. Of course, the UK is one of the first countries outside China that has a prototype specific laboratory test for this novel disease. I want to emphasise, though, that there are no confirmed cases in the UK.
My Lords, I listened closely to what the Minister said. She seemed to be referring to post-flight monitoring. Would it not be possible to have some sort of pre-flight monitoring process at the point where people depart from China? I say that as someone who has half a lung and is therefore very vulnerable.
As someone who has my own health condition, I share the noble Lord’s attitude to exposure to infection. The Chinese Government are taking strong measures in Wuhan to try to control the outbreak, including reports, confirmed by post in Beijing, that they are advising their own citizens against travel to and from Wuhan. Measures are in place there. We would welcome more timely sharing of epidemiological data on the spread of diseases from China via the WHO, and we are working through those routes to try to improve it. However, I made the point that, where we have the ability to do so, we seek to put in place the earliest possible control measures, including on-flight, so that by the time there are issues at the border we are able to intervene.
