As a teenager I read a lot of books. Books with lots of scary trends, things like nuclear weapons and overpopulation and global diseases, and I thought, 'Wouldn't it be great to write stories that showed people these problems and that we could do something about them.'

Scientists have established huge numbers of links between particular diseases and snippets of DNA, but in the great majority of cases, this has not yet been translated into treatments that can help cure patients. These treatments will come - tomorrow, or the day after.

The stunning thing about the world as it is, is that we have a tremendously large problem in it: namely, one-third of all human deaths, 80-million every year from poverty-related causes, trivial diseases and so on, and stunningly, nobody is really paying attention to it.

Just living longer and being sick is the worst. But the idea that you could have fewer diseases, and just have a healthy life and then turn out the lights, that's a good vision to have. And I think what we know about some of these pathways suggests that might be possible.

I don't like rats, but there's not much else I don't like. The problem with rats is they have no fear of human beings, they're loaded with foul diseases, they would run the place given half the chance, and I've had them leap out of a lavatory while I've been sitting on it.

New diseases like SARS and bird flu cause anxiety in the community. People get worried, some to the extent that it even affects their health. You feel very sad, and yet you must carry on and maintain your cool in very trying and difficult moments. You have to tough it out.

People are beginning to understand there is nothing in the world so remote that it can't impact you as a person. It's not just diseases. Economists are now beginning to say if we are going to have good markets in Africa, we're going to have to have healthy people in Africa.

Over time, our inescapable, systemic, fundamentally human impurity gives us the capacity to do what has not been done before: to make creative leaps in our biology, in the diseases we can resist and the foods we can digest. And in our thinking and culture and politics, too.

Grave security concerns can arise as a result of demographic trends, chronic poverty, economic inequality, environmental degradation, pandemic diseases, organized crime, repressive governance and other developments no state can control alone. Arms can't address such concerns.

I'm a vegetarian, and I long for people to eat less meat, but the thing to do is not to go, 'Eat! Less! Meat!' It's to say, 'I am fit as a flea and I'm 63, I haven't eaten meat for 40 years, and I never get diseases, I'm never ill, and I'm full of energy. So how's about that?'

Some parents are ambivalent about vaccination after reading misinformed pieces and watching misleading videos on a popular mobile chat application. By electing to avoid vaccinating their child, they are denying their child's right to be protected against these severe diseases.

In today's world, it is shortsighted to think that infectious diseases cannot cross borders. By allowing developing countries access to generic drugs, we not only help improve health in those nations, we also help ourselves control these debilitating and often deadly diseases.

I have family members who live in Africa. Because of the family that lives there, I know what is happening in these countries, and it seems so silly to me that diseases like malaria are so prevalent when they are entirely preventable. Yet children are still dying every 35 seconds.

As demonstrated by the emergence of the Mexican swine flu in the U.S., infectious diseases have little respect for borders; helping developing countries detect and deal with their diseases is the surest way for us to protect ourselves from new and potentially devastating epidemics.

I get Tweets every day from people telling me that 'Hey, I'm going to overcome my injury or my illness. Cancer. Different diseases. I can beat it because Adrian Peterson showed me the determination and the willpower to be able to prosper and get through adversity whenever it comes.'

If extreme poverty is allowed to increase, it will give rise to new problems, including new diseases that will spread from countries that cannot provide adequate healthcare to those that can. Poverty will lead to more migrants seeking to move, whether legally or not, to rich nations.

'Seanan McGuire' is my real name; if I'm being silly and third-person about it, she's a frequently cranky, foul-mouthed Disney Princess on vacation in the real world, where she studies diseases, cuddles reptiles, watches lots of horror movies, and goes to as many corn fields as possible.

A lot of medicines are not there to cure diseases. That's fine - drugs that keep people alive who wouldn't otherwise be alive are useful. What I object to is the drug companies' advertising, which you see everywhere in the U.S., which claims that they are curing diseases when they're not.

Even though we know the origin of diseases, panic sweeps. It's one thing that frightens us, because it's your health and your body - it's more like a tangible threat; it's not like a foreign enemy you can fight. That was really what was uppermost to many of us whilst making 'Black Death.'

A health system that lacks commodities for managing high-mortality infectious diseases and the main killers of mothers and young children will not have an adequate impact. By the same token, even the best-stocked delivery system will have an inadequate impact if it fails to reach the poor.

I had to have tests for cancer and other diseases - it wasn't much fun. I was getting a shooting pain in my hip and we didn't know what it was. First of all we thought it was an old injury. But they didn't find anything wrong, even though when I had an ultrasound test it was all really swollen.

Many families would like to avoid burdening future generations with inherited diseases such as haemophilia or severe developmental disorders. But most would think it wrong to edit the genes that influence the 'normal' range of human variation, from eye colour to intelligence or athletic ability.

Think about all kinds of infectious diseases, like mumps or measles or chicken pox. When a virgin population encountered those pathogens, it ravaged the population, and now they're childhood diseases, and eventually they won't even be that. That's our relationship with bacteria, going through time.

I think there's no question that vaccines have been absolutely critical in ridding us of the scourge of many diseases - smallpox, polio, etc. So vaccines are an invaluable medication. Like any medication, they also should be - what shall we say? - approved by a regulatory board that people can trust.

States should require vaccinations for communicable diseases, like measles and the mumps. But you can't catch HPV if an infected schoolmate coughs on you or shares your juice box at lunch. Whether or not girls get vaccinated against HPV is a decision for parents and physicians, not state governments.

What would be better, that people build big houses thinking that they'll make capital gains or that they send their children to medical school and they do research on curing diseases? When you put it that way, it seems obvious. There has developed a sense of personal worth that's tied to one's house.

Medicine has changed greatly in the last decades. Widespread vaccinations have practically eradicated many illnesses, at least in western Europe and the United States. The use of chemotherapy, especially the antibiotics, has contributed to an ever decreasing number of fatalities in infectious diseases.

Women will tell you, 80 percent of the time - if you listen - what is wrong with them. And what frustrates me, as a physician who takes care of a lot of women with autoimmune diseases, is that women have to request and find a physician... who will actually take their complaints seriously and investigate.

Overall, I have formed three major organizations: the National Association of Business Women, the Young Women's Leaders Network, and the Joyce Banda Foundation. Under the foundation, we have a huge program that targets women to teach them about HIV and other diseases and to give them economic empowerment.

I love that the work that we do is so vital to science. We're in a lot of ways at the scientific front line. The work that we're doing to build up the computational defense system for infectious diseases, whether it's finding the vaccine as fast as possible this time or next time to detect early outbreaks.

I wish we could have state-of-the-art hospitals in every corner of the earth... but realistically, it's going to be a while before that can happen. But we can immunise every kid on earth, and we can prevent these diseases. It's only a matter of political will, a little bit of money and some systems to do it.

When I was about 9 years old, I became very interested in the human body and diseases. In general, I was just curious about the world around me. I think that any sort of curiosity as a child is a good beginning to a career in science because science, at least to me, is a continuous exploration of the unknown.

Africa needs more funding to continue to fight all of those diseases. We are losing more than 1.3 million young children under the age of five every year because of malaria. We've already lost 25 million people to the pandemic of HIV-AIDS. More people are dying now from typhoid fever. Diabetes is on the rise.

While eliminating smallpox and curtailing cholera added decades of life to vast populations, cures for the chronic diseases of old age cannot have the same effect on life expectancy. A cure for cancer would be miraculous and welcome, but it would lead to only a three-year increase in life expectancy at birth.

My mother was a nurse, and in her era, most diseases weren't understood; people put mustard plasters on knees and rubbed camphor on your chest if you had a cough and did funny things to you if you had tuberculosis - all these things that really made very little difference once proper treatments were brought in.

I have mixed feelings about how fast things are changing as a result of technology. There's no denying that through technology there are amazing things being created that help people with diseases or help people's dreams come true. But there's also this obsession. Social media is the most dangerous of them all.

Though sporting a hideous mustache is in no way comparable to the physical pain and mental suffering men with these diseases endure, Movember still forces participants to challenge their manhood on a daily basis. Growing a moustache for men's cancer isn't as feel-good an activity as running a marathon for a cure.

Every hope of successive generations of scholars that order might be constructed from the chaotic mess of medical nomenclature has been frustrated. Even diseases recognized in the same historical period have been given names based on characteristics that have no relation to one another, and thus no common criteria.

Americans think they're the leader of the world and yet can say that they're putting their economic interests ahead of the lives of - quite possibly - tens of millions of people who over the next 50 years will die because of floods or storms or tropical diseases or whatever. I guess that sort of thing makes me angry.

The scientific community should work as hard as possible to address major issues that affect our everyday lives such as climate change, infectious diseases and counterterrorism; in particular, 'clean energy' research deserves far higher priority. And science and technology are the prime routes to tackling these issues.

Many diseases including malaria, dengue, meningitis - just a few examples - these are what we call climate-sensitive diseases, because such climate dimensions for rainfall, humidity and temperature would influence the epidemics, the outbreaks, either directly influencing the parasites or the mosquitoes that carry them.

If my dramatic career doesn't work out, I will go on to research and find cures for Alzheimer's or Parkinson's and other motor neuron diseases. It's a very exciting field of research. But I'd like to continue in drama, so it wouldn't be very smart of me if I blew this amazing opportunity with an inappropriate lifestyle.

Right now people are interested in genetic engineering to help the human race. That's a noble cause, and that's where we should be heading. But once we get past that - once we understand what genetic diseases we can deal with - when we start thinking about the future, there's an opportunity to create some new life-forms.

We hear much of Bolshevism, much of labor unrest; at times, we hear the word 'revolution.' But these are but contagious diseases in the body of civilization, and I believe that the antitoxins of good cheer, mutual confidence, fairness and justice will ultimately cure these ills and make the world healthy and strong again.

There are environmental threats to health; there are internal threats to health - genetic conditions, viral threats, diseases like cancer and Parkinson's. And then there are societal and global ones, like poverty and lack of nutrition. And unknown viral threats - everything from a new kind of influenza to hemorrhagic fever.

I imagine a day, some time in the not too distant future when children and teenagers will be able to create their own genetically engineered machines, cure the diseases of the old and find new ways to build and extend the capabilities of humanity, moving from programming software to programing the physical world, through biology.

I think all Americans believe in human rights. And health is an often overlooked aspect of basic human rights. And it's one that's easily corrected. The reason I say that is that many of the diseases that we treat around the world, I knew when I was a child. My mother was a registered nurse. And they no longer exist in our country.

In a world of serious threats to the U.K. and to global stability, where we see violence and conflict pulling people back into poverty, international terrorism, migration crises, children dying from preventable diseases and global environmental concerns on the rise, Britain's leadership on the world stage is more important than ever.

Most of us cluster somewhere in the middle of most statistical distributions. But there are lots of bell curves, and pretty much everyone is on a tail of at least one of them. We may collect strange memorabilia or read esoteric books, hold unusual religious beliefs or wear odd-sized shoes, suffer rare diseases or enjoy obscure movies.

I am deeply immersed in my medical work, and it can get very intense, but I believe that the connection and devotion is key. You can not work on diseases as devastating and deadly as Lassa and Ebola without complete trust and respect for the individuals with whom you work. My lab and colleagues are just extraordinary, and we are a family.
