Dengue headlines are hard to avoid if a trip to the Riviera Maya is coming up, and it’s fair to wonder whether that changes anything. Dengue is circulating in Quintana Roo right now, but most cases are mild, self-limited, and manageable with rest and hydration, and a short list of warning signs tells you exactly when to get checked. This guide covers what’s actually happening this season in Cancún, Playa del Carmen, and Tulum, why it happens, and what to watch for.
Dengue in the Riviera Maya: What’s Actually Happening Right Now
There is more dengue to be had in Quintana Roo this year than in the same months of last, and that holds true for the state as a whole, from Cancún to Tulum and Playa del Carmen. You will find part of the reason in the standing water left by the rains and part in the four serotypes of dengue currently making the rounds. The CDC has put dengue on its list of mosquito-borne illnesses in Mexico and advises travelers to take the usual bite-prevention measures.
The culprit is Aedes aegypti, a daytime biter that puts in its work in the couple of hours flanking sunrise and sunset. It is precisely when one might be at the beach or pool, or making the walk to a restaurant, instead of behind the safety of a net. The mosquito doesn’t need open water like the ocean or a swimming pool to breed; it will make do with an ice bucket left uncovered, a saucer beneath a potted plant or a gutter clogged from yesterday’s downpour.
Then again, risk is not uniform throughout the region. Mexican health officials put out weekly figures by municipality, and what you see at the local level may differ from the state’s headline number. During the rainy season those ratings can change from one week to the next, so the case count is less important than heeding the precautions set out here. But there is no call to scuttle your plans. Simply let the same instinct that makes you pack sunscreen prompt you to be wary of a few bites, as detailed below.
What You’re Likely Experiencing
For the majority of cases, a dengue infection is nothing more than a mild affair that won’t require a hospital stay. One can anticipate an abrupt and high fever, head pain concentrated behind the eyes, and such intense muscle and joint soreness that it is no wonder the disease is called “breakbone fever.” Nausea or a diminished appetite may be present as well, with a rash appearing in the course of two to five days.
In the early stages there is little to distinguish it from a severe case of flu, food poisoning or heat exhaustion. Then there are two other mosquito-borne conditions in the area to be aware of. Chikungunya is making inroads in the region at present; it brings on a like fever but with joint pain that is more acute and at times long lasting. As for Zika, while it is only found at low levels and tends to be milder, it poses particular dangers to those who are pregnant. Should a fever or rash come on while traveling, a physician should be seen without delay if one is expecting, no matter what the cause may be.
Is Your Dengue Mild, or a Warning Sign?
Non-severe (most cases):
- High fever accompanied by a bad headache and pain behind the eyes
- Muscle or joint aches, and bone pain
- Fatigue, nausea, and a mild rash
The course of action is to put in some rest, drink up, and take acetaminophen. Don’t reach for ibuprofen, aspirin, or any other NSAID to bring down the fever, no matter how much of a habit it is; with dengue they present a bleeding risk.
Warning signs (get checked in person, don’t wait it out):
- Tenderness or persistent pain in the abdomen
- 3 or more episodes of vomiting in 24 hours
- A sudden break in the fever that leaves you feeling worse for wear
- Bleeding from the nose or gums
- Uncharacteristic irritability or restlessness
You’ll usually see these come on between day 3 and day 7, as the fever subsides. It’s counterintuitive in that people have a tendency to let their guard down at precisely the moment they should be more vigilant. The end of the fever doesn’t mean the illness is behind you. In fact, it’s the time to be most serious about it, yet it often coincides with the last full day of a short trip, when the temptation is to pack up and make do with it.
Severe dengue (emergency, call 911 or go to the nearest hospital):
- Unrelenting vomiting or acute abdominal pain
- Any sign of bleeding, be it in the stool or vomit, or from the nose and gums
- Cold, clammy skin and trouble breathing
- Confusion
- Extreme lethargy
Cutting Your Risk Without Cutting Your Trip
- Use a DEET (20%+) or picaridin repellent, reapplied per the label, especially in the two hours after sunrise and before sunset.
- Treat clothing with permethrin if you’ll be outdoors a lot; it holds up through several washes.
- Ask your hotel about screens or reliable air conditioning over open windows. A closed, cooled room keeps mosquitoes out.
- Empty or cover anything on a patio or balcony that collects standing water, including ice buckets and plant saucers.
- Keep track of the date your fever started if one develops. The day count matters if warning signs show up later, since days 3 to 7 are the window to watch.
- Stay ahead of dehydration on hot days regardless of symptoms. It won’t prevent dengue, but it makes any fever easier to manage and easier to tell apart from simple heat exhaustion if one shows up.
- If anyone in your group develops a fever, mention any mosquito bites and the exact date symptoms started when you contact a doctor. That single detail speeds up triage more than a full symptom list.
Getting Checked in Cancún, Playa del Carmen, or Tulum
If you develop any of the warning signs above, don’t wait for symptoms to improve on their own.
In Cancún, Playa del Carmen, or Tulum, a physician can come directly to your hotel or rental, examine you in person, and arrange bloodwork if your case needs monitoring, which is the right call once dengue moves past mild. For classic mild symptoms with no warning signs, a telemedicine consultation can confirm the pattern and set a monitoring plan.
