As there are no vaccines available, basic precautions should be taken:
● Avoid tick habitats, such as long grass
● Use a recommend insect repellent containing either Icardin (20%) or DEET
● Minimize areas of exposed skin by wearing long-sleeved shirts, long pants, and closed shoes
● Carry a tick remover or fine tooth tweezers
● Carefully check every day for attached ticks
● If found remove the tick by gently gripping it as close to skin as possible and pulling away steadily without twisting or crushing the tick. Ensure the entire tick - including head and mouthparts - is removed
● Wash your skin with water and soap afterwards and apply an antiseptic cream around the bite.
● If possible, send any ticks that you have removed to a public health laboratory in your area or the National Microbiology laboratory (NML)
