===Malaria===
Refugees are often more susceptible to illness for several reasons, including a lack of immunity to local strains of [[malaria]] and other diseases. Displacement of a people can create favorable conditions for disease transmission. Refugee camps are typically heavily populated with poor sanitary conditions. The removal of vegetation for space, building materials or firewood also deprives mosquitoes of their natural habitats, leading them to more closely interact with humans.{{sfn|Kazmi|Pandit|2001|pp=1043–1055}} In the 1970s, Afghanese refugees that were relocated to Pakistan were going from a country with an effective malaria control strategy, to a country with a less effective system.

The refugee camps were built near rivers or irrigation sites had higher malaria prevalence than refugee camps built on dry lands.{{sfn|Rowland|Rab|Freeman|Durrani|2002|pp=2061–2072}}
The location of the camps lent themselves to better breeding grounds for mosquitoes, and thus a higher likelihood of malaria transmission. Children aged 1–15 were the most susceptible to malaria infection, which is a significant cause of mortality in children younger than 5.{{sfn|Karim|Hussain|Malik|Lee|2016|pp=1–12}} Malaria was the cause of 16% of the deaths in refugee children younger than 5 years of age.{{sfn|Mertans|Hall|2000|pp=103–9}} Malaria is one of the most commonly reported causes of death in refugees and displaced persons. Since 2014, reports of malaria cases in Germany had doubled compared to previous years, with the majority of cases found in refugees from Eritrea.{{sfn|Roggelin|Tappe|Noack|Addo|2016|p=325}}

The World Health Organization recommends that all people in areas that are endemic for malaria use long-lasting insecticide nets.{{sfn|Fact sheet Malaria}} A cohort study found that within refugee camps in Pakistan, insecticide treated bed nets were very useful in reducing malaria cases. A single treatment of the nets with the insecticide [[permethrin]] remained protective throughout the 6 month transmission season.{{sfn|Kolaczinski|2004|pp=15}}
