The risk of contracting malaria is low when back in the UK, if malaria treatment options such as Malarone or Docycycline. there is still a small risk despite this, and despite these medications being extremely effective, they are not 100% effective.
Malaria in the UK
In 2015, 1,400 cases of imported malaria were reported in the UK and mainly caused by P. Falciparum. The overwhelming majority of these patients had not taken precautionary measures against malaria before travelling. Anyone who visits a malaria-endemic country is at a much higher risk of acquiring malaria if no preventative measures are taken.
There are specific people in the population that are at increased risk of developing severe or complicated malaria. This includes children, pregnant women, elderly travellers and people with a reduced immune system. In the case of malaria with P. Falciparum, mortality is 20% higher in pregnant women and children under the age of three.
These specific groups of people should avoid countries that are malaria-endemic due to the increased risk of severe disease and death should they acquire malaria.
However, this may not be practical and should you need to travel in a malaria-endemic area, you should consult a health professional in person to determine what the best course of action should be.
Pregnant women can face several complications as parasites can invade the placenta; including premature birth, low birth weight, restricted growth, stillbirth and miscarriage. For more information regarding malaria and pregnancy click on http://bit.ly/RCOGPregnancyMalaria
Malaria treatment options & preventing infection
We have covered this information in a separate article on Malaria Prevention including medications to prevent malaria available on the website. You can check your risk of malaria and the right medication required to prevent malaria for your travel region on the FitForTravel website www.fitfortravel.nhs.uk.
Antimalarial tablets help protect against malaria, significantly reducing the risk by about 90%, but they are not available on the NHS. A doctor may write a private prescription, you could be seen by a travel clinic or even easier, order online from TheDoctorService.co.uk which is often much cheaper. It is key that you are taking appropriate precautions before travelling.
