Hi , not sure what the best medical advice is but we are of the opinion that its best just to be extremely vigilant with sprays , creams , mosquito nets and not to take anything if you are going to live in Moz . Best simply to be alert and if any flu like symptoms to get a full blood test , not the rapid test which can be inaccurate . Then its a three day medication with rest and plenty of fluids . We have only lived here for 10 months so possibly there is more qualified advice ...kind regards , Jonathan( xai xai )
