Every year, around 455 million get scabies. Not that you'd know, because no one talks about it.
Scabies led to the closure of migrant camps such as these in Calais, France, in 2014.
Migrants face many health problems, from mental health issues to diseases. The latest threat is scabies.
The Monkeypox virus was isolated most recently in 2012 from a dead infant mangabey (species of monkey) in Ivory Coast.
A disease suspected to be monkeypox is on the rampage in Nigeria. In less than one month, it has spread to seven of the country's 36 states and infected 31 people.
The housing situation in remote communities worsens this highly contagious parasite.
Scabies was one of the scourges of those on the First Fleet, but no longer known for most in Australian society. However, in the far remote North, scabies infection is endemic.
Children living in tropical countries and in poverty often have high rates of infection with the scabies mite.
Although a drug of known safety and efficacy is available, scabies still affects more than 100 million people across the world.
