Can dengue happen twice?

Yes, a 30-year-old female can get dengue more than once. Here's what you should know:

1. Different Dengue Virus Types:
   Dengue is caused by four different virus types (serotypes). Infection with one type usually gives you immunity to that specific type but not to the others.

2. Possibility of Multiple Infections:
   You can get dengue again if infected by a different serotype.

3. Severity Considerations:
   A second dengue infection can sometimes be more severe, so seek medical care if symptoms appear.

4. Prevention:
   Protect yourself from mosquito bites by using repellents, wearing protective clothing, and eliminating mosquito breeding sites.

If you have symptoms like high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, or bleeding, consult a healthcare provider promptly for evaluation and care.
