Health
Use bottled/treated water, avoid ice of uncertain origin, and favor hot, freshly cooked food. Malaria risk is countrywide; prevent mosquito bites day and night because dengue, chikungunya, yellow fever and Zika are also reported. Avoid freshwater swimming/wading and floodwater. Most routes are low altitude; plan for heat, humidity, sun exposure and urban air pollution.
Vaccinations
Consult a doctor or travel clinic at least 1 month before travel. Be up to date on routine vaccines, including MMR, polio, Tdap, flu, varicella and COVID-19. CDC recommends hepatitis A, hepatitis B, typhoid and yellow fever for most travelers; yellow-fever proof is required if arriving from or transiting through a yellow-fever-risk country, and may be checked as an ICVP/yellow card. Ask about malaria prevention, polio booster, meningococcal vaccine for northern/dry-season travel, and situational cholera, rabies or chikungunya vaccination.
eSIM / connectivity
eSIM is available but not as universal as physical SIMs. Major networks include MTN, Airtel, Glo and 9mobile; MTN and Airtel are common first checks for eSIM-capable visitors in large cities. Expect identity registration for local SIM/eSIM activation. If you need service on arrival, consider a travel eSIM that roams in Nigeria, often data-only, then compare local options after landing.
