Guatemala is facing its largest measles outbreak in decades. On February 24, 2026, MSPAS declared a national red alert, and the country has since mobilized over 600,000 vaccine doses in a mass campaign to stop transmission.
This page tracks the official information: how many cases there are, where they’re concentrated, how to recognize symptoms, where to get vaccinated for free, and what to do if you think you have measles. Data from MSPAS, ALMA and FUNDEGUA — updated May 7, 2026.
Quick summary: There’s an active measles outbreak with 5,821 confirmed cases and 7 deaths. The MMR vaccine is free at any health center and the only way to stop the outbreak. If you have high fever + rash + red eyes, isolate and call 2444-7474 or WhatsApp ALMA 2339-9810 BEFORE going to a health center.
Travelers from the US: should you change plans?
If you’re a US traveler considering Guatemala in 2026:
| Your situation | Recommendation |
|---|---|
| Fully vaccinated (2 MMR doses) | ✅ Travel safe with normal precautions. 97% protection. |
| One MMR dose only | ⚠️ Get a booster at least 15 days before traveling. Most US adults born 1957+ received only 1 dose under old schedules. |
| Born before 1957 | ✅ Generally considered immune (you almost certainly had measles as a child). Confirm with your doctor if any doubt. |
| Unvaccinated adult | 🛑 Get MMR vaccine ASAP at least 15 days before travel. Or postpone the trip. |
| Pregnant | 🛑 Cannot receive MMR. Discuss timing with your OB-GYN. CDC suggests postponing non-essential travel during pregnancy if outbreak is active. |
| Infant under 6 months | ⚠️ Cannot be vaccinated. Mother’s antibodies provide some protection. Avoid crowds, indoor public spaces. |
| Immunocompromised | 🛑 High risk. Discuss with your doctor before traveling. |
| Diaspora visiting family | Same rules. Vaccinate kids before traveling, especially toddlers. |
Where to verify your vaccination status before traveling: contact your primary care doctor in the US for your MMR record. Most US adults vaccinated since 1989 received 2 doses (CDC standard). Adults vaccinated 1963-1989 may have received only 1 dose, or an inactivated vaccine that requires a booster.

⚠️ About the deaths: Reported deaths so far correspond mainly to children under 5 who were unvaccinated or partially vaccinated, and to people with underlying conditions affecting their immune system. Timely vaccination prevents 97% of severe cases.
What is measles?
Measles is a highly contagious viral disease caused by Morbillivirus. It transmits through the air when an infected person coughs, sneezes, or even just breathes in an enclosed space. The virus can stay suspended in the air or on surfaces for up to 2 hours after the infected person has left.
Critical fact: one person with measles can infect 12 to 18 unvaccinated people in their environment. That’s 5-6x more contagious than original COVID-19. That’s why an outbreak escalates rapidly in populations with low vaccination coverage.
Why it’s dangerous
Measles isn’t “just a rash with fever.” Severe complications include:
- Pneumonia (1 in 20 children with measles develops it — leading cause of death)
- Encephalitis (brain inflammation — 1 in 1,000 cases, can cause permanent brain damage)
- Severe diarrhea with dehydration (especially dangerous in children under 5)
- Ear infections (can cause permanent hearing loss)
- Subacute sclerosing panencephalitis (rare but fatal — appears years after infection)
- Death (without treatment, mortality 1-3% in well-nourished children, up to 10% in malnourished children)
In unvaccinated adults, complications can be more severe than in children — especially pneumonia and encephalitis.
Symptoms: how to recognize measles
Measles does NOT start with the rash. The rash appears 3 to 5 days after the first symptoms. That’s why someone can infect many others before knowing they have measles.
Stage 1: Initial symptoms (days 1-4)
- 🌡️ High fever (over 38.5°C / 101°F, sometimes up to 40°C / 104°F)
- 🤧 Persistent dry cough
- 👃 Runny nose with discharge
- 👁️ Red and watery eyes (conjunctivitis)
- 😐 Extreme fatigue, general malaise
- 🫥 Loss of appetite
Stage 2: Koplik spots (days 2-3)
- ⚪ Small white spots inside the mouth, on cheek near molars
- They are the characteristic sign of measles — if you see them, it’s almost certainly measles
- Appear 1-2 days before the rash
Stage 3: Characteristic rash (days 4-7)
- 🔴 Flat or slightly raised red rash
- Starts on the face and behind the ears
- Spreads down to neck, trunk, arms and legs (top to bottom)
- Spots can merge forming larger patches
- Lasts 5-6 days, then peels
When it’s an emergency
Go immediately to a hospital emergency room if you experience any of these:
- ⚠️ Difficulty breathing or rapid breathing
- ⚠️ Fever that doesn’t respond to acetaminophen
- ⚠️ Seizures
- ⚠️ Confusion, extreme drowsiness, or unresponsiveness
- ⚠️ Dehydration (dry mouth, no urination, sunken eyes)
- ⚠️ Bloody diarrhea or persistent vomiting
- ⚠️ Severe headache or neck stiffness
MMR vaccine: free, safe, effective
Two vaccines are available in Guatemala against measles:
| Vaccine | Protects against | Who gets it |
|---|---|---|
| MMR (sarampión, paperas, rubéola in Spanish = SPR) | Measles, Mumps, Rubella | Children from 12 months + booster at 18 months; unvaccinated adults |
| MR (sarampión, rubéola = SR) | Measles, Rubella | Adults without complete schedule, during vaccination campaigns |
Effectiveness
- 1 dose: 93% protection
- 2 doses: 97% protection
- Immunity is essentially lifelong
- The vaccine does NOT cause measles — it contains weakened virus that trains the immune system
Where and how to get vaccinated
✅ Completely FREE at any public health center ✅ No appointment needed ✅ Just bring your DPI (or passport for foreigners) ✅ Available at: Puestos de Salud, Centros de Salud, CAP, CAIMI, public hospitals ✅ Find your nearest center: establecimientosdesalud.mspas.gob.gt
Who should NOT get vaccinated
- 🚫 Pregnant women (wait until postpartum)
- 🚫 People with severe immunosuppression (consult a doctor)
- 🚫 People with severe allergic reaction to a previous dose or its components (gelatin, neomycin)
- 🚫 Babies under 6 months (they have antibodies from their mothers)
If you’re pregnant and think you’ve been exposed, call your doctor immediately or 2339-9810. There are options (immunoglobulin) for specific cases.
What to do if you have symptoms
ISOLATE at home. Don’t go out, don’t receive visitors, especially keep children and pregnant women away. Use a separate room if possible. Measles is highly contagious 4 days before and 4 days after the rash.
CALL before going to a health center:
- MSPAS general: 2444-7474 (Mon-Fri 8 AM - 4:30 PM)
- WhatsApp ALMA 24/7: 2339-9810
- Your local health center (find it at establecimientosdesalud.mspas.gob.gt)
While you wait for instructions:
- 💧 Drink lots of water and oral rehydration solution
- 🌡️ Acetaminophen for fever (NOT aspirin — causes Reye syndrome in children)
- 🛏️ Bed rest
- 🧴 Keep eyes clean with damp cloths (don’t rub)
- 🚿 Lukewarm baths to soothe the rash
NEVER:
- ❌ Don’t go to ER or health center without calling — you’ll infect other patients
- ❌ Don’t give aspirin to children or teens
- ❌ Don’t use home remedies without consulting (some herbs can worsen dehydration)
- ❌ Don’t send children with symptoms to school
If you have severe symptoms (list above), go DIRECTLY to the nearest hospital emergency — wear a mask the entire trip.
Myths and facts about the measles vaccine
| Myth | Reality |
|---|---|
| “The vaccine causes autism” | ❌ FALSE. Over 40 studies in millions of children have debunked this. The original 1998 study was fraudulent and retracted. |
| “It’s better for the child to have the disease and develop natural immunity” | ❌ FALSE. The disease can cause death or permanent brain damage. The vaccine provides immunity without risk. |
| “If nobody vaccinates, we’ll all just get infected and be done with it” | ❌ FALSE. For every 1,000 cases there are 1-2 deaths and 1 case of encephalitis. Not an option. |
| “Vaccines contain mercury” | ❌ FALSE. MMR/MR vaccines in Guatemala don’t contain thimerosal or mercury. |
| “I’m an adult, vaccination won’t help me” | ❌ FALSE. If you’re not immune, you can be infected and seriously ill. The vaccine works at any age. |
| “If I’m vaccinated, I won’t infect others” | ✅ TRUE. Vaccinated people almost never transmit the virus. Vaccinating yourself protects those who can’t vaccinate. |
| “The vaccine hurts/causes fever” | ✅ Partly true. Can cause mild fever and redness at injection site 5-10 days later — normal and self-resolving. |
