Both dengue and typhoid cause high fever and are common in India, but they are very different illnesses — one is a mosquito-borne virus, the other a bacterial infection from contaminated food or water. Here is how their symptoms, timeline and tests differ, and why only a blood test can confirm which one you have.
Sudden high fever with severe body and joint pain (“breakbone fever”)
Pain behind the eyes, headache and a skin rash
Spread by the Aedes mosquito (daytime biter), not food or water
Falling platelet count on blood tests
Warning signs: bleeding gums, nose bleeds, black stools, belly pain
Points more towards TYPHOID
Fever that rises step-by-step over days and stays high
Spread by contaminated food or water
Abdominal pain, constipation or diarrhoea, poor appetite
A coated tongue and sometimes a slow pulse
Rose-coloured spots on the chest or abdomen in some people
When to see a doctor urgently
Bleeding from the gums or nose, blood in vomit or stools (dengue warning sign)
Severe abdominal pain, persistent vomiting or a swollen belly
Restlessness, drowsiness, cold clammy skin or fainting
Very high fever that will not come down, or fever lasting more than a few days
Reduced urine, breathlessness or a rapid heartbeat
Only a blood test can confirm it. Dengue and typhoid can look similar in the first few days. Do not self-diagnose — a doctor will use tests such as NS1/dengue serology and Widal or blood culture, along with a platelet count, to decide. MedDroid gives general information, not a diagnosis.
Frequently asked questions
Can you have dengue and typhoid at the same time?
Yes, co-infection is possible, especially in the monsoon season. That is why doctors often test for both when the fever pattern is unclear.
Which is more dangerous, dengue or typhoid?
Both can be serious if untreated. Dengue can lead to bleeding and a dangerous drop in blood pressure; typhoid can cause intestinal complications. Early testing and treatment matter for both.
Does the platelet count fall in typhoid too?
Platelets fall most notably in dengue, but they can dip in typhoid and other infections as well. The count is one clue among many, not a stand-alone diagnosis.
What tests tell them apart?
Dengue is checked with an NS1 antigen test (early) and IgM/IgG serology, with a falling platelet count. Typhoid is checked with a Widal test or, more reliably, a blood culture. A doctor interprets these together.
