<s>[INST] How is dengue diagnosed? [/INST] Dengue is diagnosed by a combination of clinical assessment of symptoms and laboratory tests. First, doctors assess the patient's symptoms described in 3. The medical history helps to find out whether the patient has been in an endemic area and may have been at higher risk of infection there. To make a final diagnosis, blood samples are taken to detect the virus or antibodies to the virus using laboratory tests such as ELISA and PCR. This helps distinguish dengue from other similar diseases. Early diagnosis is crucial as it allows for quick medical attention and helps to prevent the spread of the disease in areas populated by tiger mosquitoes. Source: BNITM.
