A traveller's risk of yellow fever is determined by their general risk assessment e.g. country visited, length of stay, city or rural, activities etc.
Mosquito bite avoidance rules should be adhered to - the mosquito that spreads yellow fever bites predominantly during the day.
Yellow fever vaccine should be considered for travellers at risk.
