Scarlet fever
Although home to only a small part of the population the Tudor municipalities were overcrowded and unhygienic. Most towns were unpaved with poor public sanitation. There were no sewers or drains, and rubbish was simply abandoned in the street. Animals such as rats thrived in these conditions. In larger towns and cities, such as London, common diseases arising from lack of sanitation included smallpox, measles, malaria, typhus, diphtheria, Scarlet fever, and chickenpox.
