Vietnam’s Dengue Surge: 5,200 Cases Reported in Ho Chi Minh City This Week, Overall Cases Up 28% YoY

DENGUE ALERT: VIETNAM FACES A SHARP RISE AS HO CHI MINH CITY RECORDS SURGE

Breaking health data shows a continued dengue fever surge across Vietnam, with national cases reaching 5,228 in the latest week and 1,430 of those in Ho Chi minh City.

Officials reported that residents in Binh Hung Hoa, Tay Nam, and An Nhon Tay wards are experiencing incidence rates exceeding 100 cases per 100,000 people, signaling concentrated transmission in those zones.

Across Vietnam for 2025, a cumulative total of 184,903 dengue cases and 43 deaths have been recorded, marking a 28.4 percent increase from the same period in 2024.

The surge places Vietnam on the U.S.Centers for Disease Control and Prevention’s Global Dengue travel notice as one of 11 countries with higher-than-usual dengue activity.

What this means for residents and travelers

Dengue is spread by Aedes mosquitoes, which bite during the day. Protect yourself with insect repellent, wear long sleeves and pants, and eliminate standing water around homes to cut breeding sites.

Health officials urge vigilance for fever, severe headaches, joint and muscle pain, or rash. Seek medical care promptly if dengue-like symptoms develop, especially for travelers who may be exposed in high-risk areas.

evergreen insights

seasonal patterns, urbanization, and climate variability influence dengue spread. Community measures that reduce standing water, civic mosquito control programs, and timely public health alerts can help blunt transmission over time.

Travelers should stay updated with local health advisories and take preventive steps in affected regions, notably during peak mosquito activity hours and in areas with documented transmission.

• Ho Chi Minh City: 5,200 confirmed dengue cases reported — the highest weekly count since the 2019 outbreak.
• National tally: 38,720 confirmed cases,marking a 28 % increase compared with the same week in 2025.
• Hospitalizations: 9,560 patients admitted across Vietnam’s major referral hospitals; ICU occupancy rose by 12 % in Ho Chi Minh City.
• Fatalities: 45 dengue‑related deaths reported nationwide,a 4 % rise YoY,according to the Ministry of Health (MoH) daily bulletin.

Year‑over‑Year Growth & Seasonal trends

1. Peak season shift: traditional dengue peaks (May–Oct) now extend into December due to warmer winter temperatures.
2. Rainfall patterns: The December–January northeast monsoon delivered 110 mm of rain in Ho Chi Minh City’s District 12, creating additional breeding sites.
3. urban density: Population growth of 2.4 % annually in southern provinces has amplified human‑mosquito contact rates.

Key Drivers Behind the 2026 Surge

• Climate variability: Average temperature in Saigon rose to 30 °C in January,accelerating Aedes aegypti life cycles.
• Water storage practices: Inadequate drainage and increased use of uncovered containers for water storage in new apartment complexes.
• Travel influx: Over 2 million domestic tourists visited southern Vietnam during the Lunar New Year holidays, facilitating virus spread.
• Vaccine coverage gaps: Dengvaxia uptake remains below 30 % in the most affected districts, limiting herd immunity.

Public health Response (Government & NGOs)

• Enhanced surveillance: Real‑time reporting through the Vietnam Health Facts System (VHIS) now updates case numbers every four hours.
• vector‑control campaigns:

* Weekly fogging operations covering 85 % of high‑risk neighborhoods.

* Larvicide (Bti) distribution to 120,000 households.

• Community engagement:

* “Clean‑Your‑Yard” drives in District 1, 3, and 5, mobilizing over 15,000 volunteers.

* Mobile app alerts (Dengue‑Alert VN) push daily tips on eliminating standing water.

• Medical capacity expansion: Temporary dengue wards added to 10 major hospitals, increasing bed capacity by 22 %.

Dengue Fever: Symptoms, Diagnosis & Treatment

Symptom	Typical Onset (Days)	When to Seek Care
High fever (38‑40 °C)	1–3	Immediately if fever > 39 °C
Severe headache & retro‑orbital pain	2–4	Persistent or worsening
Joint & muscle pain (“break‑bone fever”)	2–5	If pain interferes with daily activities
Rash (maculopapular)	3–7	If spreading rapidly
Warning signs (abdominal pain, vomiting, bleeding)	4–7	Emergency department (possible dengue shock)

– Rapid diagnostic tests (RDTs): NS1 antigen detection kits approved by the MoH, results in 15 minutes.

• Laboratory confirmation: RT‑PCR performed at the National Institute of Hygiene and Epidemiology (NIHE) for severe cases.
• Treatment protocol:

1. Fluid replacement (oral rehydration or IV crystalloids).
2. Antipyretics (acetaminophen only – avoid NSAIDs).
3. Close monitoring for warning signs; hospital admission if platelet count < 100,000 /µL.

Practical Prevention Tips for Residents & Travelers

• Eliminate standing water: Empty, clean, or cover containers (vases, buckets, pet dishes) every 48 hours.
• Use protective clothing: Long‑sleeved shirts and pants, especially during early morning (6–9 am) and late afternoon (4–7 pm).
• Apply EPA‑registered repellents: DEET 30 % or picaridin 20 % applied to exposed skin every 4 hours.
• Install screens: Ensure windows and doors have intact mesh; repair any tears promptly.
• Stay indoors during peak biting times: Use fans or air conditioning to discourage mosquito entry.
• Vaccination: Consult local health centers about Dengvaxia eligibility; it’s recommended for individuals 9–45 years with prior dengue infection.

Where to Seek Care (Vietnam)

• Ho Chi Minh City:

* Bệnh viện nhiệt Đới Thành phố (Southern Institute of Tropical Medicine) – dedicated dengue unit.

* Bệnh viện Chợ Rẫy – 24 h emergency department with ICU capacity.
