The other three active cases arrived from England, Egypt and Pakistan. Four of the 23 cases were deemed historical. India has the third-highest number of cases in the world, behind the United States and Brazil, and is experiencing a rising rate of reported cases. Of the nearly 100,000 cases a day in India, about half are in the state of Maharashta, of which Mumbai is the capital, so there's a “very active outbreak there”, Bloomfield said. Many cases experience the onset of symptoms pre- or during travel to New Zealand, Bloomfield said. On Wednesday there were seven new cases of the virus announced in managed isolation.
