Dengue fever is one of the most common mosquito-borne viral infections in India, particularly during the monsoon and post-monsoon seasons. It is transmitted by the bite of the Aedes aegypti mosquito and can range from a mild flu-like illness to a severe, life-threatening condition. Recognising the early warning signs and acting promptly is vital to prevent complications and ensure timely medical care.

WHAT IS DENGUE FEVER?

Dengue is caused by the dengue virus, which has four distinct strains (DEN-1 to DEN-4). A person can be infected more than once, and subsequent infections may carry a higher risk of severe disease. Symptoms usually appear 4–10 days after being bitten by an infected mosquito. While mild cases may resemble seasonal fever or fatigue, severe dengue can result in bleeding, organ damage, or even death if not treated promptly.

Unlike many common fevers, dengue progresses in phases. It begins with a sudden onset of high fever and flu-like symptoms, followed by a critical phase where complications may arise if not managed carefully. This is why identifying early red flags is crucial.

EARLY WARNING SIGNS YOU SHOULDN’T IGNORE

1. SUDDEN HIGH FEVER

One of the most noticeable early symptoms of dengue is a sudden spike in temperature, often reaching 104°F (40°C). The fever appears abruptly and is usually continuous, sometimes accompanied by chills and severe discomfort. A fever that persists beyond two days, especially during dengue season, should never be ignored.

2. SEVERE HEADACHE AND PAIN BEHIND THE EYES

Dengue causes a distinctive headache that is sharp and throbbing, often focused in the forehead. Many patients also experience pain behind the eyes (retro-orbital pain), which worsens with eye movement. This combination is a classic hallmark of dengue.

3. MUSCLE, JOINT, AND BONE PAIN

Nicknamed “breakbone fever,” dengue is notorious for causing intense body aches and joint pain. Unlike regular viral fevers, the discomfort in dengue is severe enough to limit daily activities and may feel like deep bone or muscle pain.

4. SKIN RASH AND RED SPOTS

A red rash or small red patches often appear 2–5 days after the fever begins. These spots result from bleeding under the skin and may resemble measles. While not always present, rashes alongside fever and body pain strongly suggest dengue.

5. NAUSEA, VOMITING, AND ABDOMINAL PAIN

Persistent nausea, abdominal cramps, or repeated vomiting are common in dengue. These symptoms may also indicate the illness is progressing toward a more severe stage and require urgent medical attention.

6. UNUSUAL FATIGUE AND WEAKNESS

Dengue often leaves patients feeling drained, with extreme tiredness that doesn’t improve even after adequate rest. This fatigue is much more pronounced than in ordinary viral infections.

SEVERE WARNING SIGNS: SEEK IMMEDIATE HELP

While mild dengue can be managed with supportive care, it’s crucial to recognise the warning signs of severe dengue, which can be life-threatening if untreated. Watch out for:

  • BLEEDING: Nosebleeds, bleeding gums, blood in stool or vomit, or easy bruising due to low platelet counts.
  • SEVERE STOMACH PAIN: Persistent abdominal pain or tenderness signals disease progression.
  • DIFFICULTY BREATHING: Fluid accumulation in the chest may cause breathlessness.
  • SUDDEN DROP IN PLATELETS: Confirmed by blood tests, a sharp fall in platelets increases the risk of uncontrolled bleeding.
  • COLD OR CLAMMY SKIN: This may indicate shock, a critical medical emergency.

WHY EARLY DIAGNOSIS MATTERS

There is currently no specific antiviral treatment for dengue. The cornerstone of recovery is supportive care—hydration, rest, and close monitoring. However, missing early warning signs allows the disease to escalate quickly, leading to complications such as dengue haemorrhagic fever or dengue shock syndrome.

Timely diagnosis through simple blood tests can make all the difference. With early medical intervention, the majority of patients recover without lasting complications.

PREVENTION IS KEY

Because dengue spreads through mosquito bites, prevention is just as important as treatment.
Practical steps include:

  • Using mosquito repellents and wearing long-sleeved clothing.
  • Keeping windows closed or using mosquito nets.
  • Eliminating stagnant water in pots, containers, and coolers where mosquitoes breed.
  • Cooperate in neighbourhood and community mosquito-control drives like fumigation.

CONCLUSION

Dengue fever may start with symptoms that resemble the flu, but its potential to become severe makes it a condition that should never be underestimated. Early warning signs such as persistent high fever, severe headache, retro-orbital pain, muscle and joint aches, rash, nausea, or unusual bleeding require immediate medical evaluation.
