The fact that I was fortunate enough to escape contagion, in spite of frequent, sometimes daily contacts with the disease, was because I soon guessed how it spread.

The discovery that I soon made that the guinea pig was also susceptible to infection made it possible for me, from the third year on, to preserve the virus on this animal.

From the practical point of view, the susceptibility to infection of the guinea pig proved to be the most useful step forward. Today, all laboratories use this animal for preserving the virus.

I was less successful in my attempts to effect preventive vaccination against typhus by using the virus and in trying to produce large quantities of serum using large animals.

My first attempts to transmit typhus to laboratory animals, including the smaller species of monkeys, had failed, as had those of my predecessors, for reasons which I can easily supply today.

I finally demonstrated that typhus infection is not hereditary in the louse.

Just as the only reservoir for the typhus virus in nature is provided by man, so the only vector of infection is the louse. The bite of the louse is not virulent immediately after the infecting meal. It becomes so only towards the 7th day following infection.

Even if it had not been possible to reproduce the disease in animals and consequently to verify the hypothesis, this simple observation would have been sufficient to demonstrate the way in which the disease was propagated.

Most of the doctors in the Tunisian administration, especially those in country districts, contracted typhus and approximately one third of them died of it.

Of all the problems which were open to me for study, typhus was the most urgent and the most unexplored. We knew nothing of the way in which contagion spread.

I demonstrated the characteristics of experimental fever. It appears after an incubation period which is never less than five days. It follows the same pattern as natural fever in man, but is of shorter duration and less pronounced.

At the time when I was conducting my research there was no known method for taking the guinea pig's temperature. I demonstrated a technique which is now widely used.

It did not seem likely that I was destined to undertake research on typhus.

Cancer is just a horrible disease.

From the very commencement the student should set out to witness the progress and effects of sickness and ought to persevere in the daily observation of disease during the whole period of his studies.

On January 1, 2006, Medicare will begin to offer a prescription drug benefit, and for the first time, it will place an emphasis on preventive care and early treatment of disease.

Fascism is a worldwide disease. Its greatest threat to the United States will come after the war, either via Latin America or within the United States itself.

It's far more important to know what person the disease has than what disease the person has.

The United States cannot feed every person, lift every person out of poverty, cure every disease, or stop every conflict. But our power and status have conferred upon us a tremendous responsibility to humanity.

The worst disease which can afflict business executives in their work is not, as popularly supposed, alcoholism; it's egotism.

We live in a time when the words impossible and unsolvable are no longer part of the scientific community's vocabulary. Each day we move closer to trials that will not just minimize the symptoms of disease and injury but eliminate them.

Fear is a disease that eats away at logic and makes man inhuman.

The fact that I was fortunate enough to escape contagion, in spite of frequent, sometimes daily contacts with the disease, was because I soon guessed how it spread.

If I found a cure for a huge disease, while I was hobbling up onstage to accept the Nobel Prize they'd be playing the theme song from 'Three's Company'.

I'm never getting too lonely because it's the kind of disease where you might sit in front of the TV with three bags of biscuits, rather than communicate with the world.

Hastiness and superficiality are the psychic diseases of the twentieth century, and more than anywhere else this disease is reflected in the press.

We recognized in 1996 that, with progress in the field of genetics accelerating at a breathtaking pace, we need to ensure that advances in treatment and prevention of disease do not constitute a new basis for discrimination.

God - a disease we imagine we are cured of because no one dies of it nowadays.

I really connect with those moments of doing missionary work down there and just seeing the people that are dying from disease and hunger and malnutrition.

I'll also tell you that five hundred thousand people will die this year of cancer. And I'll also tell you that one in every four will be afflicted with this disease, and yet, somehow, we seem to have put it in a little bit of the background.

Advances in technology and in our understanding of illness and disease together with an expanded workforce and greater resources will allow us to provide more services to a higher quality.

It is much more important to know what sort of a patient has a disease than what sort of a disease a patient has.

Pearl is a disease of oysters. Levant is a disease of Hollywood.

The disease is painless; it's the cure that hurts.

War is the symptom, not the disease.

I have been heartbroken once and it has affected all my relationships from there on. But now I look at it as a occupational hazard. If you are in the meat market at some point you are gonna get mad cows disease.

There are zillions of people who say that alcoholism is a disease, but not many of them believe it.

Aggression unopposed becomes a contagious disease.

Western civilization, Christianity, decency are struggling for their very lives. In this worldwide civil war, race prejudice is our most dangerous enemy, for it is a disease at the very root of our democratic life.

It is the American vice, the democratic disease which expresses its tyranny by reducing everything unique to the level of the herd.

Everybody's journey is individual. If you fall in love with a boy, you fall in love with a boy. The fact that many Americans consider it a disease says more about them than it does about homosexuality.

For somehow this disease inheres in tyranny, never to trust one's friends.

Childhood is a disease - a sickness that you grow out of.

Breast cancer is not just a disease that strikes at women. It strikes at the very heart of who we are as women: how others perceive us, how we perceive ourselves, how we live, work and raise our families-or whether we do these things at all.
