Dengue fever, a viral infection transmitted by Aedes mosquitoes, has become a global health concern. With over 390 million cases reported annually, recognizing its symptoms is crucial for timely diagnosis and treatment. This comprehensive guide explores the telltale signs and symptoms of dengue, empowering individuals to safeguard their health.

When to Seek Medical Help:
If you experience any of the symptoms mentioned above, especially if you have recently traveled to a dengue-endemic area, it is crucial to seek medical attention promptly. Early diagnosis and treatment can significantly improve outcomes.
Treatment for Dengue:
