The Norwegian Institute of public health has issued a warning that those travelling back to their home countries have a higher risk of infectious disease than other travellers. This applies especially to malaria, hepatitis A, typhoid among others.
Migrants who travel back to a country with a high rate of malaria, slowly loose their immunity over time. Migrants from India and Pakistan are most at risk. They NIPH recommend taking preventative measures against malaria, and to protect agains mosquitoes.
This especially important when travelling with children. Children travelling to tropical regions can begin their vaccination earlier to ensure they are fully vaccinated and immunised before they travel. Contact your local doctor for more information about when to start the childhood immunisation programme.
