Honest about the risks, and specific about what prevents each one.
Animal bites and scratches
CDC states dogs infected with rabies are commonly found in Morocco and that animal bites and scratches can lead to serious diseases such as rabies. The Government of Canada says rabies is carried by dogs and some wildlife including bats, that it spreads mainly through bites but also through scratches, and that it is almost always fatal once symptoms appear. Its list of animals to avoid is broader than most people expect: stray dogs, livestock, monkeys, snakes, rodents, birds and bats.
Prevention Do not feed, pet or photograph strays at close range, and keep children within armโs reach of you rather than of the animals. If skin is broken: wash long and hard with soap and running water, then seek medical care immediately, however minor it looks. CDC notes rabies vaccines are typically available throughout most of Morocco โ knowing where "most" runs out on your route is part of the plan.
Travellerโs diarrhoea
The Government of Canada calls it the most common illness affecting travellers, with higher risk where hygiene and sanitation standards are poor or food handling is unsafe, and notes young children, older travellers and people with existing health problems are more at risk.
Prevention Its own rule is the shortest one worth memorising: boil it, cook it, peel it, or leave it. Bottled or treated water, ice only where you trust the kitchen, food cooked fresh and served hot. Rehydration salts weigh nothing, and we can send you with a standby antibiotic where that is appropriate.
Heat and sun
CDC warns that heat-related illness such as heat stroke can be deadly, and asks travellers to protect themselves from ultraviolet radiation โ sunscreen of at least SPF 15, protective clothing, and shade between 10am and 4pm, with extra care during summer months and at high elevation.
Prevention Eat and drink regularly, loose lightweight clothing, and limit physical activity when it is hottest. Plan desert and medina walking for early and late in the day, and treat a mid-afternoon Sahara excursion in July as a decision rather than a default.
Cold in the mountains
The same CDC outdoor guidance that names heat also warns that very cold temperatures can be dangerous, and asks travellers to stay alert to changing weather and adjust plans if conditions become unsafe. In Morocco this is the High Atlas rather than the cities, and it surprises people who packed for Marrakech.
Prevention Dress in layers and cover head, hands and feet properly. Check conditions before a trekking day and be willing to turn a route around. Neither source raises altitude illness for Morocco โ if you are going high, bring the itinerary and we will talk it through in person.
Freshwater โ and a gap between the sources
CDC states that schistosomiasis, a parasitic infection spread in fresh water, is found in Morocco, and says to avoid swimming in fresh, unchlorinated water such as lakes, ponds or rivers. The Government of Canada does not name schistosomiasis for Morocco at all; it gives the general advice to avoid getting water in your eyes, mouth or nose when swimming in freshwater, especially after heavy rain or flooding. We show you both rather than pick one.
Prevention Stay out of still and slow fresh water โ irrigation channels, ponds, river pools below the waterfalls. Chlorinated pools and the sea are a different question. Do not swallow water when showering, bathing or in hot tubs.
Sandflies and leishmaniasis
The Government of Canada says both the cutaneous or mucocutaneous form and the visceral form can occur in Morocco, though the risk is low for most travellers. It is spread by the bite of an infected sandfly, symptoms can appear weeks or months later, and sandflies are most active between sunset and sunrise in rural, forested and some urban areas. CDC also names leishmaniasis and answers it with "avoid bug bites".
Prevention CDC asks for a repellent containing 20% or more DEET, and long sleeves, long trousers and a hat to cover exposed skin. Sunset to sunrise is the window that matters here, which is exactly when people sit outside.
Roads
The Government of Canada notes that not all drivers respect traffic regulations, that pedestrians, scooters and animals on roadways pose risks, that accidents causing fatalities are common, and that you should avoid driving at night. CDC names motor vehicle crashes the number one killer of healthy travellers abroad.
Prevention No night driving, especially on rural and mountain roads. Reputable drivers and operators for long transfers rather than the cheapest option, and a four-wheel drive with proper supplies if you are going off-road in the mountains or desert.
Getting treated, and paying for it
The Government of Canada says the quality of medical care varies greatly across Morocco, that Casablanca, Marrakesh and Rabat have good private facilities for non-emergencies, that care in public facilities is not up to Canadian standards, and that doctors and hospitals often expect immediate cash payment. It also notes tuberculosis risk is low for most travellers but higher for some โ people visiting or working in prisons, refugee camps, homeless shelters or hospitals, and travellers visiting friends and relatives.
Prevention Travel insurance that covers medical evacuation and hospital stays, with the policy number saved offline. Carry enough cash to start treatment, keep a list of local doctors and hospitals, and pack a travel health kit โ the Government of Canada asks for one especially if you are heading away from major city centres.
