“Richard felt that they should not paint too black a picture, and that in any case there was no proof of contagion since the relatives of his patients were still unaffected. ‘But others have died,’ Rieux pointed out. ‘And, of course, contagion is never absolute, because if it were, we should have endless exponential growth and devastating loss of population. It’s not a matter of painting a black picture; it’s a matter of taking precautions.’ However, Richard thought he could sum the situation up by saying that if they were to halt the disease, assuming it did not stop of its own accord, they had to apply the serious preventive health measures provided for in law; that, to do so, they would have to acknowledge officially that there was an outbreak of plague; that there was no absolute certainty on that score; and consequently that they should consider the matter.”
