 Quarantine measures against ships coming from the Dutch Republic were put in place in 29 other ports from May, starting with Great Yarmouth.The Dutch ambassador objected at the constraint of trade with his country, but England responded that it had been one of the last countries introducing such restrictions.Regulations were enforced quite strictly, so that people or houses where voyagers had come ashore without serving their quarantine were also subjected to 40 days of quarantine.
