In some of the most dangerously overcrowded Greek refugee camps, it has become a race against time to raise awareness about Covid-19 and ensure an outbreak does not spread among an already vulnerable population.
In the infamous Moria camp on the island of Lesbos close to 20,000 people live in a space designed for just under 3,000.
There is is already limited access to running water in the camp, and toilets and showers regularly block due to overuse. The first case of Covid-19 was confirmed on the island last week when a Greek woman from the town of Plomari tested positive. So far this the only confirmed case on the island.
