Medical
People do get sick on vacation. There are certain local dangers.
Generally speaking, the guide books avoid any real discussion of
them as they don't wish to frighten you. They are also usually written
by people who are either not from this area or don't do much exploring
and are unaware of the realities of jungle life. This subject is
especially important if you plan to visit vegetated areas outside
the Cancun Hotel Zone.
Jungle Life
The most beautiful thing about Cancun is that you can be in the
jungle within five minutes. Despite the closeness to civilization,
it will still be real jungle, no matter how small a piece. An American
tourist was lost for 19 days in the San Gervasio park in Cozumel,
despite the best efforts of search teams that included helicopters
and planes. He survived by eating small fish that he caught with
his hands and finally walked out on his own.
Except for mosquitoes and an occasional tabano, stinging or biting
vermin are mostly a problem outside Cancun proper. Be careful when
exploring outside the urbanized area. Never go barefoot in any vegetation,
including hotel lawns (See "Mosquitoes, zancudo" below). Some ruins,
such as Ruinas del Rey and Kobá , are in clearings in dense
jungle. Use insect repellent, wear shirts, long pants, socks and
shoes and stay on the beaten path
See Insect Repellents, for insect
repellents and sun protection
African bees
There is a very thorough government program to trap all African
bees, as the Yucatan Peninsula is one of the most important honey-producing
areas in the world. The hives develop rapidly, however. There have
been cases of severe attacks in other parts of the Yucatan, but
not in Quintana Roo. Never touch any insect hive. Report any hives
to maintenance or security personnel.
The bees seem to react to actions they perceive to be aggressive,
so be really calm and slow if you find yourself being examined by
inquisitive, small dark bees. Don't brush at them or make rapid
movements of any kind; just let them lose interest, then slowly
move away. If attacked, the best strategy is probably to dive into
the water.
We are getting more information about this. It's not much of a
problem here in Cancun so far, but hives have been detected and
removed, one right in the garden of the residential complex where
we live. The bees buzzed Jesse and Anita, but lost interest when
they remained cool.
Agua mala
During late April through June, a stinging organism called agua
mala or sea lice is prevalent in these waters. An itching hive results
within four or five hours after it brushes against you. Always shower
immediately after coming out of the ocean. Be sure to rinse under
your bathing suit and apply water vigorously to your belly button
and all hairy areas such as underarms and pubic hair. If you do
get these itchy swellings, which look like a rash rather than mosquito
bites, there are a couple of remedies: Logoderm, a cortisone-based
creme available in any local drugstore, applied twice daily is a
big help. Soyaloid polvo, a poultice applied twice daily will also
relieve the itching. Plain white vinegar also helps, especially
if sponged on immediately after coming out of the water.
Chakistes
These are tiny, almost invisible gnats. The bites usually don't
itch very long, but outside of Cancun there are varieties that can
be as bad as mosquitoes and even get right through screens and mosquito
nets. Proper clothing and insect repellent are the only remedies.
Fortunately, chakistes are quite variable depending upon season
and climate conditions. The best strategy when they do swarm is
to move inside. When the wind shifts or the sun moves, they tend
to disappear.
Diarrhea
This subject is covered in the other guides, but deserves some
comment. The best way to avoid an infection is to wash your hands
and face frequently, especially after going to the bathroom. Don't
eat unpeeled raw fruit and, in general, stay away from raw food
of any kind. Major hotels use sterilizing solutions on salads, so
it's quite safe to eat these. When eating outside your hotel, stick
to cooked food and don't fall into the temptation of eating from
small street-side stands. We have some more advice about this under
"Restaurants."
Cancun city water comes from deep wells. It is filtered and chlorinated
at the well and then re-purified by many of the hotels. When it
leaves the well it's at least as safe as your home tap water, which
is not saying much, given the current state of most community water
systems and all the things that can happen from the well to your
faucet. As a visitor, you should stick to bottled water See "Water".
Most tourist diarrheas in Cancun are caused by the change in the
mineral content of the water, the increased intake of raw fruits
and dehydration resulting from the heat and alcoholic beverages.
This kind of diarrhea is self-limiting and will usually be gone
within 24 hours.
The best treatment is to rest, stay off booze but keep your fluid
intake up, and eat bland food. Kaopectate or Pepto-Bismol will help,
but don't medicate yourself with drugs such as Lomotil, which will
mask the symptoms of a real infection.
Severe Diarrhea
If your diarrhea is very severe, or you throw up, see a physician
right away for symptomatic relief. This is the only way to be sure
that you have a transient diarrhea rather than an infection, which
must be treated with the correct medicines.
Any diarrhea with severe cramping and/or fever or lasting more
than 24 hours is probably an infection and should be attended to
by a physician. It is better to treat this here than to wait until
you get home, as our doctors are more experienced in identifying
the specific infection by its symptoms alone and treating it correctly.
A complete laboratory test takes three days, so most infections
are treated pragmatically in the case of tourists here on short
visits. Laboratory services here are very inexpensive and you should
always have your stool examined if there is time. We feel very strongly
that any diarrhea lasting more than 24 hours in a child must have
a laboratory analysis, even if it is only a microscopic examination,
which will take not more than a few hours.
If the infection persists when you return home, you should see
a specialist in intestinal parasites rather than your family doctor.
Always insist that your stool be tested in a laboratory, preferably
by the culture method. The more common parasites and infections
-- amoebas, giardia, salmonella, shigella -- are easily identified
and treated. If none of these show up, the infection may be a yeast.
To find this, the culture should be taken from within the rectum
rather than from the stool. All parasites, bacterial infections
and yeasts will respond to the correct treatment. If you don't get
better, change doctors.
Despite what you might read about the horrors of amoebas and other
parasites, they are unlikely to become dangerous even when untreated,
except in the infirm. Although this is nothing you want to confirm
by self-neglect, it is true even of children. A well-nourished and
healthy human being can fight off almost any infection. Deaths from
infant diarrhea, for example, although the single greatest cause
of infant mortality in tropical regions, occur almost exclusively
among the lower classes in malnourished children who are not properly
treated. Cancun has the lowest infant mortality rate in Latin America,
much better than many communities in the United States.
Mosquitoes
As a result of what we consider over-spraying by the government,
but they consider merely prudent business, there are hardly any
mosquitoes left in the Hotel Zone. There are still mosquitoes in
town, especially in vegetated areas. Outside of Cancun, they can
be as thick as snowflakes at certain times, usually just before
and after sunset and after rain. We remember thirteen straight days
of rain when we were living in Playa del Carmen. The mosquitoes
were so numerous one day that when we tried to go shopping, we had
to give up and run home.
If you sight-see in vegetated areas, wear long-sleeved shirts and
trousers and socks, especially during mosquito hours (dawn and dusk),
when it is better to stay inside. When selecting accommodations
outside of the Cancun Hotel Zone, make sure to check the screens
for good repair and tight fit. If you see blood smears on the walls,
beware. Mosquito repellents do work, but the best bet for extended
stays outside of urban Cancun is to sleep under mosquito netting
-- called pabellón here, and available in Mercado 23, El
Parian, and Hamacas El Aguacate in Plaza Bonita. The nylon kind
is the best.
The itching of mosquito bites can be temporarily relieved with
applications of 96º alcohol, available in any supermarket or
drugstore. We like the red label best. They say you can drink it,
but we've never tried it, even though it is marked "potable." The
blue label is denatured and doesn't smell as good. Some mosquitoes,
called zancudos, leave raised welts that itch ferociously. They
hatch in the roots of grass and the bites are most frequent on the
ankles and can take up to two weeks to heal. Cortisone cremes can
help relieve the itching.
Portuguese Man o' War
Prevalent only during certain wind conditions and seasons, this
jellyfish looks like a purple balloon with hanging tentacles. Don't
touch them. The stings are painful but not dangerous. The local
remedy is to bathe the affected part in urine. A papaya or meat-tenderizer
poultice will also help.
Scorpions
We have seen many scorpions, especially when living outside of
Cancun. They are extremely unaggressive and will sting only if molested.
Faera is the only one in our family who has ever been stung by a
scorpion, despite living on the borders of the jungle for months
at a time. It was not a very traumatic event and did not require
medical attention. Most scorpion stings are painful but not dangerous,
especially in this area. The most venomous scorpions are small and
pale. Any child under the age of eight stung by a scorpion should
receive immediate medical attention. So should adults who experience
any change in breathing or produce thick, ropy mucous. These danger
signs will appear soon after the sting. Although it is a good idea
to see a physician, it is not necessary for routine scorpion stings,
which will be uncomfortable for about twenty-four hours. Fatalities
are extremely rare. Almost all occur in the state of Durango, which
has especially venomous scorpions.
Sea Urchin Spines
Usually affecting skin-divers only, these are very painful, but
respond to the urine/meat tenderizer treatment.
Snakes
Don't go off the beaten path in vegetated areas. Never touch a
snake. Any snake bites should be attended to immediately by a physician.
We have heard of only one serious snake bite since 1983 hereafter
Hurricane Gilbert, when the snakes in the Puerto Morelos herpetarium
escaped, and one of them bit a women. She was in grave danger but
recovered.
Spiders
I accidentally left my moccasins in Akumal on an excursion in 1983
and had to walk barefoot on the path to the grotto at Xcaret. I
felt a slight sting on his left foot and killed a small black insect.
The grotto seemed unusually beautiful when we went swimming. The
following day, my foot was black and swollen and my left eye was
twitching. Medical treatment cleared up the problem rapidly. The
doctor thought it might have been a Black Widow spider.
Stinging Corals
Skin-divers will sometimes have reactions after touching or brushing
against certain corals. The local remedy is to wash the affected
area in urine and/or apply meat tenderizer to destroy the offending
alien proteins. Your dive instructor will know what to do. The best
advice is don't touch coral or other underwater fauna.
Tabanos
Tabanos are large yellow flies, similar to horse flies, prevalent
during the summer months, but found here all year 'round, especially
on beaches outside of Cancun. The tabano has a distinctive flight
pattern of rapid circles around its potential victim. It's always
a good idea to kill any tabano that starts stalking you, as they
tend not to give up once they make up their mind to bite. This is
easier if two people cooperate. Generally speaking, you will not
feel the bite itself, but there will be an extremely intense itch
soon afterward. It can be quite painful, lasting for days. Many
people are completely immune to tabano bites, but others suffer
an allergic reaction in which the bitten area swells, sometimes
grotesquely. We haven't discovered any real remedy for tabano bites.
I used to get the swelling, but now seem to be more immune. I found
some relief by holding the affected area under the hottest water
I could stand, which intensified the itch at first, but then reduced
the annoyance.
