The seven warning signs of dengue fever include severe abdominal pain, repeated vomiting, bleeding from the nose or gums, blood in vomit or stools, extreme tiredness or restlessness, difficulty breathing or a swollen abdomen, and cold, clammy skin. Although most cases of dengue are mild, the condition can become serious very quickly.<\/p>\n\n\n\n
Many people mistake dengue for a common fever and choose to recover at home. However, the dangerous phase can begin just as the fever goes away and the patient starts feeling better. Recognising the early symptoms and warning signs of dengue can help patients seek medical attention at the right time.<\/p>\n\n\n\n
This guide explains the early symptoms of dengue, seven warning signs that should never be ignored, and when to visit a hospital.<\/p>\n\n\n\n
Dengue fever is a viral illness transmitted through the bite of an infected Aedes mosquito. These mosquitoes usually bite during the day, particularly in the early morning and late afternoon. They breed in stagnant water found in coolers, buckets, flowerpots, and old tyres.<\/p>\n\n\n\n
Dengue does not usually spread directly from one person to another. The symptoms generally appear between four and ten days after an infected mosquito bite.<\/p>\n\n\n\n
Most people recover within about a week. However, some patients develop severe dengue, which can cause blood vessel leakage, bleeding, and a drop in platelet counts. Recognising the warning signs can help patients receive timely medical care.<\/p>\n\n\n\n
The early signs and symptoms of dengue often resemble those of other viral infections. Common dengue fever symptoms include:<\/p>\n\n\n\n
These symptoms usually last between two and seven days. Many patients recover with rest, adequate fluids, and medical guidance. However, new or worsening symptoms require medical attention.<\/p>\n\n\n\n
Dengue warning signs may indicate that the illness is progressing towards a more serious stage. If any of the following symptoms appear, seek medical attention immediately rather than waiting for them to disappear.<\/p>\n\n\n\n
Severe or persistent stomach pain is an important warning sign of dengue. The pain may become worse over time, and the abdomen may feel tender when touched.<\/p>\n\n\n\n
This can indicate fluid leakage or other complications affecting the body. Patients experiencing severe or persistent abdominal pain should seek immediate medical attention.<\/p>\n\n\n\n
Repeated vomiting can cause dehydration and make it difficult for the body to maintain its fluid balance.<\/p>\n\n\n\n
If vomiting continues or prevents the patient from drinking water or ORS, medical attention is necessary. Persistent vomiting should never be ignored during dengue fever.<\/p>\n\n\n\n
Some patients may experience nosebleeds, bleeding gums, easy bruising, or small red spots on the skin.<\/p>\n\n\n\n
Dengue can affect blood clotting and may be associated with a reduction in platelet counts. Any unusual bleeding during dengue should be assessed by a doctor immediately.<\/p>\n\n\n\n
Blood in vomit may appear red or resemble coffee grounds. Stools may contain visible blood or become black and tar-like.<\/p>\n\n\n\n
These symptoms can indicate bleeding in the digestive tract and require emergency medical attention.<\/p>\n\n\n\n
Unusual weakness, excessive sleepiness, restlessness, or irritability may indicate that the patient’s condition is worsening.<\/p>\n\n\n\n
Children may become unusually quiet, refuse to play, or show changes in their normal behaviour. Any sudden change in alertness or behaviour should be taken seriously.<\/p>\n\n\n\n
Dengue can cause fluid to leak from blood vessels and collect in the abdomen or around the lungs.<\/p>\n\n\n\n
Patients may experience abdominal swelling, rapid breathing, or shortness of breath. Difficulty breathing requires immediate emergency medical care.<\/p>\n\n\n\n
Cold hands and feet, pale or clammy skin, a weak and rapid pulse, and fast breathing may indicate poor circulation or shock.<\/p>\n\n\n\n
This is a medical emergency that requires immediate treatment. Patients experiencing these symptoms should be taken to the emergency department without delay.<\/p>\n\n\n\n
Do not ignore symptoms when the fever drops.<\/strong> Dengue warning signs often appear around the time the fever goes away, particularly during the following 24 to 48 hours. A lower temperature does not always mean the patient has recovered. If the patient starts feeling worse or develops any warning sign, seek medical help immediately.<\/p>\n\n\n\n Dengue is generally divided into three phases. The timing can vary from person to person.<\/p>\n\n\n\n Patients should continue monitoring their symptoms during the critical phase, even if the fever has disappeared.<\/p>\n\n\n\n Severe dengue is a potentially life-threatening form of the illness. It can cause serious complications, including problems affecting organs such as the heart and kidneys. Delayed treatment can increase the risk of complications.<\/p>\n\n\n\n There is no specific antiviral treatment for dengue. Medical care focuses on managing symptoms, maintaining hydration, and closely monitoring the patient’s condition. This is why recognising warning signs and seeking hospital care at the right time are important.<\/p>\n\n\n\n During the first few days, dengue and other infections can produce similar symptoms. The following table highlights some common differences, but symptoms alone cannot confirm the infection.<\/p>\n\n\n\nWhen Do Dengue Warning Signs Appear?<\/h2>\n\n\n\n
