My Lords, we welcome the WHO recommendations, and the Government are considering our response. PHE’s experts are liaising closely with WHO and other agencies to understand the developing evidence and give the best advice possible. Given the serious implications of a link with microcephaly, the current travel advice is highly precautionary. Those travelling to affected areas should review this advice, pregnant women should consider the need to travel and all travellers should take scrupulous bite avoidance measures.

I thank my noble friend for that reply. It is helpful to know that there is a rapid response call for research applications aimed at tackling the Zika virus. Does my noble friend agree that the immediate priority is to eliminate the species of mosquitoes which spread the virus? Will the Government support field trials with Latin American nations into the release of genetically modified non-replicating mosquitoes, as recommended by the Science and Technology Committee in December?

My Lords, I think we are the second biggest contributor of funds to WHO and have just contributed £6.2 million to its emergency contingency relief fund. I think that the work that we have done in the UK on developing genetically modified mosquitoes to combat this disease and other diseases spread by mosquitoes will almost certainly play a very major part as we go forward.

My Lords, since there is no prospect of an early vaccine to deal with Zika, is not the only show in town which could deliver an early answer to Zika the genetically modified mosquitoes to which the noble Earl, Lord Selborne, referred? This is a mosquito that has been modified so that its offspring die off before they can develop, and it is a mosquito that transmits both the dengue and the Zika virus. Since there has been astonishing success in the Oxitec company’s trials in parts of Brazil which, after the release of hundreds of millions of the modified mosquitoes, has virtually extinguished dengue, should the Government not support and fund extended trials by this company in Brazil? That would be extremely good not only for the reputation of British science but for the economy, since this is a field in which Britain leads the world.

There is no doubt that the work that we have done in this country on developing genetically modified mosquitoes will play a very large part in tackling Zika and other infectious diseases of this type. Sally Davies, the Chief Medical Officer, has convened a science committee which is meeting either today or tomorrow to assess the issues raised by the current outbreak. I am absolutely sure that she will be considering what the noble Lord has said as part of our response.

My Lords, obviously effective control is essential, but since the WHO declaration we have had news of a sexually transmitted case of the virus. What lessons are the department taking, or what can they take, from this in terms of guidance and action in this country, particularly for travellers?

My Lords, there has been one case where Zika may have been sexually transmitted—I use the words “may have been” advisedly because it is not proven. Indeed, the link between Zika and microcephaly is not yet scientifically proven. There seems to be a strong probability that that is the case, but we should bear in mind that Zika was first identified back in 1947 in Africa and since then there has been no such connection with microcephaly, although in Brazil there appears to be a very strong connection now. There has been one case in Texas, where there may have been sexual transmission and the advice for men who are sleeping with women who may become pregnant is to wear a condom.

My Lords, while absolutely agreeing that we should carry on supporting the science of genetically modified mosquitoes, it may be that mosquitoes that are already genetically modified for dengue can do the same job for Zika, but we do not know that. Much more important is the recent report and questions about the assessment of the spread of the Zika virus. The Minister has just referred to sexual transmission, but that applies to any bodily fluids, not just sexual transmission. The other worrying thing is that the common mosquitoes have now been found possibly to be infected by Zika. That is a much more worrying prospect, because they are much more widespread.

I understand that the common mosquito which we find in southern Europe could potentially carry Zika, which I think was reported in the Times today. There is as yet no evidence that it does carry Zika, but it is something that we need to watch very carefully.

My Lords, is the fever notifiable, so that a record is kept of this event?

My Lords, one of the problems of this illness is that four out of five people are asymptomatic—they have no symptoms. For many of the others, the symptoms are such that it is a very light cold or light flu. That is one of the problems with this illness.

With the Olympic Games coming up, are particular precautions being considered and are you in contact with the organisations dealing with travel to the Games?

Comprehensive travel advice is on a number of different websites. The Royal College of General Practitioners and the Royal College of Obstetricians and Gynaecologists have been notified and the information has been cascaded down, so I think that there will be enough travel advice as we near the Olympics.

My Lords, is the Minister aware that in Brazil around 80,000 women die from unsafe abortion because of the lack of provision there? This figure will surely increase as a result of this terrible disaster. Is there any way that our Government can put pressure on the Brazilian Government to allow safe abortion in that country?

My Lords, that strays slightly away from the brief that I have on the subject today. May I take that on consideration? I will raise it with my honourable friend in the other House, the Minister for Public Health.

My Lords, are the aeroplanes coming from the countries where there are these mosquitoes being sprayed?

My Lords, that is something that is under consideration at the moment. It varies from airline to airline—that is the truthful answer at the moment—but we are considering whether all flights from areas that have Zika virus should be sprayed.
