I am travelling from Hanoi to Ho Chi Minh city via Haalong Bay, Hue and Hoi An, all are Costal areas. Should I take Malarone? I would prefer not to as I am trying to get pregnant.
In Vietnam, costal areas north of Nha Trang are considered malaria-free, as are the cities of Hanoi and Ho Chi Minh city. As such, it is only rural and costal areas closer to Ho Chi Minh city where you might be at risk. One option you have is to take mefloquine (Lariam) – it is safe to take while pregnant (or trying to get pregnant), and is effective in most areas of Vietnam. There is resistance to mefloquine in the Mekong Delta region, but it doesn’t sound like you will be travelling there, so this shouldn’t be a problem.
