That this House has considered World TB Day and the efforts to end tuberculosis globally.
I am delighted to be able to introduce this debate. It was World TB Day on Sunday, but this is not an anniversary that we should be having to mark at all. It is wrong and extraordinary that we still have to debate the toll from death and suffering of a disease that has been curable for well over half a century, since the discovery of antibiotics by Fleming in 1928. It is unnecessary that so many people die from tuberculosis.
Imagine if the World Health Organisation announced tomorrow that a new disease had been discovered that was highly infectious, airborne and susceptible to drug-resistance, and that next year 10 million people would fall sick, of whom 1.6 million people would die. Imagine the global response to that news. That is in fact a description of the reality of tuberculosis. TB kills more people every year than HIV/AIDS and malaria combined —1.6 million people last year. Of course, there is overlap between HIV/AIDS and TB, because the AIDS epidemic in the 1980s drove the resurgence of tuberculosis. A disease that the world thought it had beaten has come back with a vengeance.
TB was first declared a global health emergency 25 years ago, in 1993. Since then, 50 million people have died. Just consider that. A disease is declared a global health emergency and subsequently 50 million people die, yet that disease is treatable and curable. That represents nothing less than a catastrophic failure on the part of the world’s Governments to deal with a disease that we should deal with more effectively.
Dr Dan Poulter (Central Suffolk and North Ipswich) (Con)
My right hon. Friend is making some good points and I congratulate him on securing the debate. He mentions the failure of world Governments. There is clearly a need for greater urgency in the approach taken by the international community in dealing with this issue, but what about the behaviour of pharmaceutical companies, which rarely invest in drugs that will help people in low and middle-income countries in the way that they would do in lucrative medications that they can sell in higher income countries, such as Great Britain?
My hon. Friend makes a good point, but I do not blame pharmaceutical companies, because I think this is a clear case of market failure. The fact is that the demand for better TB drugs, which we need, falls largely in low and middle-income countries, so there is no commercial case for sufficient investment in these new drugs. It can therefore proceed only on a public-private partnership basis. Some pharmaceutical companies have a pro bono programme for the drugs that do exist, such as Johnson & Johnson, where there is a drug to deal with drug-resistant TB. However, that is still insufficient.
This market failure is a striking contrast with what happened with AIDS. There was a serious response to the AIDS epidemic from pharmaceutical companies, not only from publicly funded programmes, but from commercially funded investment. As a consequence we have had extraordinary innovation, and new drugs that can prevent HIV and ensure that it is not a death sentence are available. What is the difference between the two? AIDS was a disease that was killing people in the west and TB is a disease that kills the poor. That is the fundamental difference. That is why we have not had the same level of investment in tuberculosis. Another fundamental difference is that TB was already curable with antibiotics. It is just that these antibiotics were not being delivered, TB patients were not being identified and we did not have the health systems to do it.
Dr Poulter
I am a little more sceptical about the operation of some pharmaceutical companies than my right hon. Friend. In fact, one reason that the global community was able to so effectively deal with HIV—he is right to identify TB as an AIDS-defining disease—was that international Governments brought pressure to bear on pharmaceutical companies to drop the price of the medications, and push medications out in low and middle-income countries. That has not happened with TB. Unless there is a concerted effort from global Governments to encourage pharmaceutical companies to behave with greater global awareness and corporate responsibility, I am not sure we will see much change in the situation that he is describing, and change is badly needed.
This is an interesting debate, but I disagree with my hon. Friend. The drugs are not in the pipeline, because the return on investment for these companies is insufficient in the first place. I do not think that they are sitting on drugs that are available for wealthier people, which, if pressed, they could simply roll out to poorer people. There is an insufficient quantum of investment in research and development. I will come on to that point. I do not think that the need can be met by the private sector alone.
I believe that there are three key reasons why we need to take more action against this disease: humanitarian reasons, economic reasons and reasons of global public health. The humanitarian reason is that so many people are dying needlessly from this disease and falling sick. The figures speak for themselves.
The economic reason is that this awful loss of life and this illness are a drag on economic success in the poorest countries, hindering their development. There will also be a serious economic impact if we fail to tackle the disease. By 2030, it is estimated that if the current trajectory of TB continues, that will cost the world’s economies $1 trillion. Some 60% of that cost will be concentrated in the G20, and it will be caused by the 28 million deaths over that period. That is a terrible statistic, because that is the period over which tuberculosis is meant to be beaten according to the sustainable development goals. The United Nations set those goals four years ago, and said that the major epidemics—AIDS, malaria and TB—would be beaten in 15 years’ time. We have just 11 years to go. On the current trajectory, TB will not be beaten for well over 100 years. There will be a further 28 million deaths during that period alone, as well as huge economic costs.
The global public health reason is the susceptibility of tuberculosis to drug resistance, because of the old-fashioned drugs that are used to treat tuberculosis. People who take the drugs do not continue with their treatment and it is a very serious fact that there are well over 500,000 cases of drug-resistant TB in the world. The highest burden is actually in the European region. Only one in four people who have drug-resistant TB can access treatment.
The right hon. Gentleman is making a very powerful case. He has just said that because so many cases are undetected, the risk is compounded. That is an important issue, which needs tackling urgently.
I strongly agree with the hon. Gentleman. I commend the work he does on the all-party parliamentary group on global tuberculosis, which I have the honour to co-chair with my friend, the hon. Member for Ealing, Southall (Mr Sharma). The big problem is all of these undetected cases. We need to find and then treat millions more people.
There is hope. Last September, the UN convened the first high-level meeting on tuberculosis, which passed a strong declaration that recommitted the world to meeting the sustainable development goal target to beat the disease, and that specifically set a new target of diagnosing and treating 40 million cases of TB by 2022—a very tight timetable. It is vital that efforts are stepped up immediately so we can meet that new, ambitious target. It will require a significant increase in the level of spending on TB programmes globally from nearly $7 billion to $13 billion and on tuberculosis research and development from $700 million to $2 billion a year.
Two key issues arise from those ambitious new commitments, the first of which is accountability. How are we going to hold the world’s nations to account for their commitments at the high-level meeting? I mentioned that the world has already declared TB a global health emergency and has already set the sustainable development goals. The problem is that we keep talking about the disease but not delivering a sufficient global response to beat it, so accountability is crucial.
Among the problems with the otherwise good declaration passed at the UN is that independent accountability was struck out, but it is vital, because we have to hold countries’ feet to the fire for what they have committed to do. Accountability can take multiple forms: it can be done through bilateral relationships; intergovernmental platforms at the G20, the G7 and the Commonwealth; a further review of the UN high-level meeting and the commitments made; or international institutions such as the World Health Organisation. I must say, however, that if the WHO’s existing mechanisms had been effective, we would not be in this position.
It is a pleasure to see you presiding today, Sir Christopher, and to follow the right hon. Member for Arundel and South Downs (Nick Herbert), whom I congratulate on securing the debate. I am grateful for the leadership that he continues to provide, and for his comprehensive introduction, which makes it easier for those of us who want to speak—
Not at all; it was a great speech, and well delivered.
As the right hon. Gentleman said, TB remains the world’s deadliest infectious disease. Despite it being entirely curable, it has claimed 1.3 million lives in the last year, including the 700 children who died every day.
According to the British Society for Immunology, one third of the world’s population is infected with the TB bacterium. We urgently need to enlarge our treatment of the illness and make vaccines that are safe, affordable and accessible. The BSI states that that is especially essential for pulmonary TB. We all know the tremendous impact that widely available vaccines could have on combating the disease, as the right hon. Gentleman has said; they are absolutely essential. Will the Minister comment on how much funding the Government can allocate to investing in the research to develop such vaccines?
Funding research into vaccines is especially important because of the increasing number of TB cases that are resistant to multiple antibiotics. That is an issue around the world, with more than half a million cases of drug-resistant TB reported in 2017. I ask the Minister what work is ongoing with colleagues to ensure that the Global Fund to Fight AIDS, Tuberculosis and Malaria is replenished as a means to combat the global spread of drug-resistant TB, as requested by the right hon. Gentleman.
The disease has played an important part in the history of public health in my Tower Hamlets borough. The UK has a high incidence of TB compared with much of western Europe, and London accounts for one third of UK cases. In my borough, the levels have decreased in recent years, which is good news. Incidence has halved from 64.7% in 2010 to 32.5% in 2015, but TB continues to affect Tower Hamlets disproportionately compared with other parts of the country.
Tuberculosis is a disease of poverty, and my constituents are among of the most vulnerable. The approach to tackling this complex disease needs to incorporate not only research into vaccines and cures, but spreading awareness to individuals who possess the aforementioned social risk factors.
As well as the health issues, is it not true that people with TB are socially isolated and excluded because of the effect on other people in the community? I wonder whether that is the experience in Tower Hamlets, because it is certainly the experience in places such as India.
It certainly is. Of course, one of the big downsides is that the risk of spreading the infection means that there has to be some degree of isolation, guilt and emotional stress. My hon. Friend makes a very important point.
The approach to tackling this complex disease needs to incorporate not only research into vaccines and cures but spreading awareness to individuals who possess the aforementioned social risk factors. Early intervention is also key to ensuring that the disease is treated swiftly and the risk of spreading it is minimised. That is why I am pleased that the Government are overseeing the national TB strategy for England between 2015 and 2020, enacted by TB control boards. With this approach, I am sure we will continue to see a decline in cases of TB in Tower Hamlets.
It is simply not acceptable for 10 million people globally to be falling ill from TB in 2019. This disease is curable and with the right funding treatments could be made easily accessible. Our Government need to continue to intervene to ensure that adequate investment is allocated to research vaccinations, to work with global partners and to play our part in eradicating TB worldwide.
I would be grateful to the Minister if she could confirm what is being done to work with other nations to deliver on the UN high-level meeting on TB target to find and treat 40 million people by 2022.
I start by congratulating the right hon. Member for Arundel and South Downs (Nick Herbert) on spelling out how important this issue is. I also pay tribute to everybody worldwide who is working in one way or another to fight TB, whether it is on research or on the frontline of dealing with TB and finding people, supporting them and curing them of this terrible disease.
I was fortunate enough to visit Cambodia with RESULTS UK some years ago and saw the fantastic work going on, with partners from across the world working with the Cambodian health authorities to try to reach people suffering from this disease, to tackle it and root it out, but it is a forever challenge.
When I mention TB to people in everyday parlance, they believe that it is a disease of the past—a disease of the 19th century—and are surprised when I point out the fact that it is the biggest killer in the world today. We should be ashamed that that is the case because, as the right hon. Gentleman said, with the proper will, effort, focus, determination and drive, this disease could be sorted. The resources are there to tackle it. It is a matter of purpose, intention and marshalling our forces. That is partly what this debate today is trying to do.
One third of the world’s population is infected with the tuberculosis bacterium, which is a shocking figure. Annually, more than 10 million people become ill with TB, resulting in 1.6 million deaths. As my hon. Friend the Member for Poplar and Limehouse (Jim Fitzpatrick) has just pointed out, the UK has a higher incidence of TB than we would wish. We have a higher incidence than the USA or other western European countries, with hotspots in places such as London, Leicester, Luton, Birmingham, Manchester and Coventry.
Indeed, when I was principal of a sixth-form college in Scunthorpe, there was an outbreak in the town, which first focused my mind and made me understand the process of ridding a small community of the disease. It is difficult and requires a lot of work. That brought home to me how much it needs sorting, because TB is an airborne disease and adults with pulmonary TB are the main transmitters, which makes it particularly problematic to root out.
It is a pleasure to serve under your chairmanship today, Sir Christopher.
I congratulate the right hon. Member for Arundel and South Downs (Nick Herbert) on securing this important debate, but more importantly I congratulate him on his strong and consistent leadership and on the work of the all-party parliamentary group on global tuberculosis.
I declare a relevant interest. I visited Liberia with RESULTS UK in 2017 to look at its post-Ebola healthcare system strengthening. My hon. Friend the Member for Brighton, Kemptown (Lloyd Russell-Moyle) was part of that delegation and I understand, Sir Christopher, that if he catches your eye he will say a little more about what we learned.
Goal No. 3 of the sustainable development goals is good health and wellbeing. It commits the world to bringing about an end to TB by 2030. We know that, given the current rate of progress, we will miss that target by 150 years. As the right hon. Gentleman said, the UN high-level meeting on TB political declaration includes a commitment to find and treat 40 million people with TB by 2022. If we are going to do that, we not only need to diagnose but to successfully treat 8.5 million people this year, which is 2 million more people than were officially diagnosed in 2017.
As we have heard, later this year we have the sixth replenishment of the Global Fund to Fight AIDS, Tuberculosis and Malaria, which is a critical opportunity to mobilise efforts to build stronger and more resilient health systems. The Global Fund is an incredibly important mechanism for donors, recipient countries, civil society and the private sector to come together in response to these epidemics. Since it was founded in 2002, the Global Fund has helped to save over 27 million lives and that is in no small part due to the generous involvement of the United Kingdom.
Almost a fifth of Global Fund annual funding goes to fighting TB—as the right hon. Gentleman reminded us, that is 70% of all of the international financing that exists to fight tuberculosis. The UK played a leading role during the last replenishment cycle, but if we are going to close the gap in the finance that is required to meet the targets that have already been described, all donors—including the UK—need to step up their financial commitment to the Global Fund.

We know that there are 3.5 million missing cases of TB every year that are simply undiagnosed, accounting for one in three sufferers. The proportion is much higher for drug-resistant TB, where 71% of people are missing. This constitutes not only a humanitarian issue, but a serious risk to global public health, because this is an airborne, highly infectious disease.
My first point to the Minister, who I welcome to her place, is that the UK has a vital role to play in ensuring that there is more effective, sharper and independent accountability for the targets set at the high-level meeting. Without that accountability, I fear that we will not meet those new targets, and if we do not, we do not have a chance of beating the disease within the set timeframe.
The second issue is that we cannot escape the fact that we will need additional resource to meet the ambitions and that must come from the countries affected, particularly middle-income countries, which must find the resources to deal with it. We have seen a huge improvement in the response in India, for example. Resource must also come through multilateral institutions, particularly the Global Fund to Fight AIDS, Tuberculosis and Malaria, through which comes 70% of all international funding for TB. The UK can be proud that it is the third-largest contributor.
This year marks the replenishment of the Global Fund. If we are to have a hope of meeting those TB targets, it is vital that it is replenished to a higher level than before. The investment case requires a pledge of $14 billion from the world’s countries, which will be combined with an increase of nearly 50% in domestic investment, so the money will also come from individual nations. That would suggest that the UK needs to commit £1.4 billion, which is an increase on the £1.2 billion it gave last time. That is the minimum that will be required to meet the Global Fund’s strategy targets and is proportionately the same as the UK previously gave, at about 13% of the budget.
I know other hon. Members want to speak, so I will make one final point. As my hon. Friend the Member for Central Suffolk and North Ipswich (Dr Poulter), who is no longer here, said, new drugs will be essential. New drugs for tuberculosis have become available only relatively recently; there have been no new drugs for more than 40 years. Most people do not know that we do not have an effective adult vaccine for tuberculosis, and no epidemic in human history has ever been beaten without one. We have to be able to meet the new targets for an increase in research and development, which includes providing public funding.
Again, the UK has a vital role to play because of the strength of our pharmaceutical sector and what we already do on research and development. We need a specific plan to implement a research strategy; we need to establish a baseline for countries to ensure that they are funding their fair share of research and development; and we need to establish a mechanism to co-ordinate that spend. Otherwise, again, countries will talk about the research and development gap, but never do anything to close it.
We should not need to be here. This is not a disease that we should have to talk about any longer—frankly, it is a moral disgrace that we still are. It is a needless loss of life. Many problems confront modern Governments, some of which are nearly intractable. This is not one of them. This disease can be beaten. We have known how to do that for more than half a century and, with new tools, we could do it better. In the words of the Stop TB Partnership’s campaign for World TB Day last Sunday, “It’s time” to beat this disease.
We need a safe and affordable vaccine urgently and we need the significant investment in research worldwide to deliver it. As the right hon. Member for Arundel and South Downs pointed out, that can be done with the proper effort. There are loads of reasons to explain why that is not currently happening but, as has been said, a specific research strategy needs to be put in place and funded.
The Minister is an excellent Minister, and I know she will be very much on board and well-researched already. She has an opportunity to contribute to the global leadership in this process. We are six months from the next UN high-level meeting on TB and the time for replenishment of the Global Fund to Fight AIDS, Tuberculosis and Malaria is fast approaching. The last UN high-level meeting on TB had lots of positives, but there were also areas where we could have asked for a bit more regarding the accountability that we would like so that people own the process and take it forward.
As the right hon. Gentleman pointed out, if the UK can commit to the £1.4 billion that is needed from us over the next three years to up our global game, that would be the UK playing the role that it has always played—one of global leadership, in a way that partners can stand alongside—and I am sure the Minister would want to be part of that. By making those strides, we will begin to make the strides that are necessary to get rid of this terrible disease, one that we should not still have and that is curable—one that is get-riddable. We need to do that and we need to do it now.
As the right hon. Gentleman said, drug resistance has complicated the fight against TB, as it has the fight against other diseases. TB is a curable disease, but it requires strict, continuous treatment with a number of antibiotics over many months. As others have said, TB is now responsible for one in three deaths worldwide from drug resistance. If we do not step up our global efforts, we risk a resurgence in the incidence of TB, which could have a catastrophic impact on public health and the global economy.
The theme of the global goals is to leave no one behind, and addressing a health emergency is central to that. I reiterate to the Minister what others have said: we have an extraordinary opportunity. UK civil society has said that we want to step up in commitment. It has called on the British Government to pledge £1.4 billion to the Global Fund’s vital work over the next three years. I hope the Minister will respond positively on the UK’s continued commitment to tackling deadly diseases.
As we have heard, accountability is central. It involves working with civil society, working with citizens in the countries that are most affected and working with the key multilaterals—the World Bank, the United Nations and the Stop TB Partnership—so that we have a comprehensive plan that brings to an end tuberculosis by the target date of 2030. I hope the Minister will demonstrate once again the strong and clear leadership that is needed, so that we rise to the challenge in the months ahead.
