Chaos - Fleas and Rats

Last week we started a new focus on a topic which is "The Black Death", we had learnt how this disease spread around the globe and what caused it to become one of the most dangerous disease on Earth. The Black Death came to Europe in 1347 and killed millions, in medieval times places like the houses and towns were not so clean and had poor hygiene which made it easier for the Black Death to spread. It first started in Asia and spread among soldiers, it then travelled across over-seas and popular trading places which then the traders caught the disease making it a whole lot easier for it to spread around the globe. Now how this started was it began from Fleas and Rats, rats were mostly common in middle ages, due to the poor hygiene the rats were everywhere (houses, trading ships, churches, farms, castles & etc). We assume that when fleas bite the rodents and since rodents are in common places like houses it then transfers to humans and much quicker for it to spread.
