For those travelling and returning from Brazil it is important to be aware of the Zika Virus.
The infection is suspected of leading to thousands of babies being born with underdeveloped brains.
What are the symptoms?
Deaths are rare and only one-in-five people infected is thought to develop symptoms. These include:
- mild fever
- conjunctivitis (red, sore eyes)
- headache
- joint pain
- a rash
A rare nervous system disorder, Guillain-Barre syndrome, that can cause temporary paralysis has been linked to the infection.
There is no vaccine or drug treatment so patients are advised to rest and drink plenty of fluids.
But the biggest concern is the impact it could have on babies developing in the womb and the surge in microcephaly.
