Do I need any especial vaccine?
No, you are not required to present any vaccination certificate in order to visit this beautiful destination.
What should I do in case of illness?
Most of the big hotels have doctors amongst their staff. You can also go to any of a number of hospitals and clinics in Manzanillo (See site of hospitals and clinics).
Is potable water reliable?
The hotels offer their guests purified water; ask at the reception desk about its quality.
In any case, it is never an excess to drink bottled water only. You must also avoid drinking the beverages or "cool drinks" that are offered at the stands on the streets. Their hygiene is pretty dubious.
What precautions should I take regarding food?
Manzanillo's typical cuisine is a temptation hard to avoid. Its exquisite fishes and seafood are the basis of several traditional dishes, which are usually over seasoned and very spicy, something that can cause discomfort on the visitors' health.
It is advisable to walk slowly through the "streets" of flavour;
meaning, be frugal until your organism gets used to the spicy seasoning
If in spite of these precautions you were to suffer a stomach disorder, a rather common malady amongst travellers, drink abundant purified water. If the problem should persist, ask a doctor.
How do I avoid getting sunburnt?
Bear in mind that the ideal way of getting a nice tan is by beginning with short-time periods of exposition, which can be progressively stretched in order to avoid having your skin damaged by the sun. Try not to stay too long under the rays of the sun king during the first days.
Do not fail to use sunscreen and to drink plenty of water so that your skin will remain hydrated. If you were to suffer sunburns or erythemas, do not hesitate in soliciting medical assistance.
