All the world is topsy-turvy, and it has been topsy-turvy ever since the plague.

The sick man is the parasite of society.

Diseases, at least many of them, are like human beings. They are born, they flourish, and they die.

If we wait for a pandemic to appear, it will be too late to prepare.

The best quarantine is hygiene.

Health care delivery is one of the tragedies still in America.

We should always presume the disease to be curable until its own nature proves it otherwise.

It is strange indeed that the more we learn about how to build health, the less healthy Americans become.

If they prescribe a lot of remedies for some sickness or other, it means that the sickness is incurable.

Health in all lands is among the indispensable guarantees of human progress.

Men worry over the great number of diseases, while doctors worry over the scarcity of effective remedies.

Even diseases have lost their prestige, there aren’t so many of them left.

Plagues are as certain as death and taxes.
