The diseases of the present have little in common with the diseases of the past save that we die of them.

Everyone who is sick is someone else’s patient zero.

The sick man is the parasite of society.

Men take diseases, one of another. Therefore let men take heed of their company.

Disease makes men more physical, it leaves them nothing but body.

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

What timid man does not avoid contact with the sick, fearing lest he contract a disease so near?

Infectious disease is one of the few genuine adventures left in the world.

Diseases are not immutable entities but dynamic social constructions that have biographies of their own.

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

Health can make money, but money cannot make health.

The best quarantine is hygiene.

I have learned much from disease which life could never have taught me anywhere else.
