Despite the doctors not knowing how to treat the disease, they stood by the sick people.
Here, we can see an example of the doctors famous uniform during the different episodes of the Black Death in the crisis of the Middle Ages and Modern Times. They invented it in order not to be infected by the patients.
The uniform consisted of a long dress, a stick to be able to touch the sick from a distance, glasses and a mask with a very long nose filled with medicinal herbs to, supposedly, avoid contagion.

Doctors did not know how to stop the disease, but in some places quarantine was used to prevent the arrival of sick people in the cities.
Ragusa, Dubrovnik (Croatia) was the first city to approve a pioneering law in 1377 to apply quarantines as a method to avoid contagion.
This law said that all boats and commercial caravans coming from infected areas had to undergo 30 days of isolation before entering the city.
In Venice, the first isolation hospital in history (1423) was established on a small island just off the Lido.

However, it was most common that people fled the cities believing they could avoid the plague, but only succeeded in infecting many more people.
