Honest about the risks, and specific about what prevents each one.
Schistosomiasis in fresh water
Both sources place it in Egypt. The Government of Canada describes tiny worms found in fresh water — lakes, rivers, ponds and wetlands — that break the skin, with eggs that can cause stomach pain, diarrhoea, flu-like symptoms or urinary problems, and says most travellers are at low risk. There is no vaccine and no preventive medication. CDC advises against swimming in fresh water in developing areas or where sanitation is poor.
Prevention Stay out of the Nile and any canal, lake or pond — no swimming, wading, bathing or swallowing. Sailing on it is not the risk; being in it is. Chlorinated pools are fine, and so is the Red Sea. If you did go in, tell a clinician when you get home rather than waiting to feel unwell.
Traveller’s diarrhoea
The Government of Canada calls travellers’ diarrhoea the most common illness that affects travellers, and says the most important thing to do is to maintain hydration by drinking lots of fluids. CDC notes food and water standards vary by destination. It is the single most likely thing to cost you a day of the itinerary.
Prevention The old rule still works: boil it, cook it, peel it, or leave it. Bottled or boiled water including for brushing teeth, ice only where you trust the kitchen, and do not swallow water in the shower or pool. Rehydration salts weigh nothing, and we can send you with a standby antibiotic where appropriate.
Heat
CDC is direct about it: heat-related illness, such as heat stroke, can be deadly, and it advises staying alert to changing weather conditions and adjusting plans if conditions become unsafe. Egypt is where this bites — Luxor and Aswan in summer, and open desert sites with no shade at midday. The Government of Canada adds that sand and dust storms can occur in the spring, with sand-laden winds at high speed creating difficult driving conditions.
Prevention Sites early or late, not at midday. More water than feels necessary, plus salt with meals. A hat, loose long sleeves and real sun protection. Know the warning signs — headache, dizziness, confusion, stopping sweating — and act on them in someone else before they do. If you take a diuretic, a beta blocker or anything that affects sweating, raise it at the appointment; some regular medicines change how you handle heat.
Roads
The Government of Canada says road conditions are often poor and the rate of car accidents in Egypt is one of the highest in the world. CDC names motor vehicle crashes the number one killer of healthy travellers abroad and advises against driving at night, noting street lighting in parts of Egypt may be poor.
Prevention No intercity driving after dark. Use your hotel or tour operator’s driver rather than the cheapest option, and wear a seatbelt in the back as well as the front.
Mosquitoes and sandflies
Both sources name dengue as a risk in Egypt, spread by mosquito bite, with no vaccine or medication available in Canada to prevent it. Both also name cutaneous and mucocutaneous leishmaniasis, spread by sandfly bite, with the Government of Canada describing the risk as low for most travellers and noting there is no vaccine or medication to prevent it. CDC additionally lists Zika and African tick-bite fever, and Crimean-Congo haemorrhagic fever from tick bites.
Prevention Repellent through the day, not only at dusk — the dengue mosquito bites in daylight. Long sleeves in the evening, screened or air-conditioned rooms, and check for ticks after desert or rural walking. If you are pregnant or trying to conceive, raise Zika before you book rather than after.
Animals and birds
CDC says dogs infected with rabies are commonly found in Egypt, and advises not touching or feeding animals you do not know. It also lists Rift Valley fever from contact with the blood, body fluids or tissue of infected livestock. The Government of Canada reports human cases of avian influenza in Egypt and advises avoiding contact with birds, alive or dead, and with surfaces that may carry droppings.
Prevention No touching street dogs, cats or any animal at a site or market, however friendly. Any bite, scratch or lick on broken skin: wash the wound with soap and clean water and see a doctor the same day — CDC is explicit about both steps. Keep clear of live bird markets and poultry farms, and eat poultry and eggs properly cooked.
Diving and the Red Sea
The Government of Canada notes that outdoor activities such as scuba diving, snorkelling, hiking and other extreme sports can be dangerous, and that safety standards and rescue services may not match what Canadians expect.
Prevention Use an operator that will show you its equipment and its certification. Check that your travel insurance actually covers diving — many policies exclude it, or cap the depth. Leave a day between your last dive and your flight home.
Getting treated
The Government of Canada is short and unambiguous: medical facilities are below Canadian standards, and travellers should get insurance that covers medical evacuation and hospital stays. CDC adds the practical version — carry a list of local doctors and hospitals, and bring your medicines from home rather than expecting to buy them there.
Prevention Travel insurance with medical evacuation, and the policy number saved offline rather than only in email. A written medication list, generic names included. Enough of your regular medicines for the trip plus a few days, in labelled original packaging.
