Insects like mosquitoes are responsible for transmitting viruses like that of dengue.

How is it diagnosed and treated?

The doctor will perform a physical examination to detect increased body temperature and other symptoms of viral fever. He will then order blood tests to check for the presence of viral antibodies (antibodies to various viral infections) and diagnose the exact cause of the fever. Other specific tests might be done to identify the virus along with imaging tests like ultrasound and chest X-ray.

The exact treatment of viral fever will vary depending on the cause. The doctor may recommend the following general therapies:

  • Pain relievers to reduce the pain
