Eswatini

Eswatini is the consultation where geography writes the prescription. Malaria lives only in the eastern lowveld — Lubombo and the eastern edges of Hhohho, Manzini, and Shiselweni — so the classic tourist circuit through Mbabane and the Ezulwini Valley needs no prophylaxis at all, while a night at Hlane or Mkhaya absolutely does, and the parasite there is chloroquine-resistant falciparum. Know your itinerary before the appointment; it changes the answer.

The background reality is HIV at roughly 27% — the world's highest prevalence — which changes the risk math of any road accident or blood exposure. That means a proper wound-care kit, universal precautions if you're rendering aid, and a PrEP conversation for some travelers. It also deserves the counterweight: Eswatini was the first African country to reach the UNAIDS 95-95-95 targets, an extraordinary public-health achievement. Care itself is modest — Mbabane Government Hospital and Raleigh Fitkin Memorial in Manzini are the referral centers, Good Shepherd in Siteki covers the malaria zone — and anything complex flies to Johannesburg, three to four hours out. Two practical traps: South Africa transit requires two consecutive blank passport pages, enforced at the border, and photography of anything governmental, military, or royal without permission is genuinely prosecuted. Skip the rivers — schistosomiasis is real here.
