Dengue fever is a reemerging global disease and a growing concern for US residents traveling to tropical areas. Primary care physicians should be aware of this tropical disease as it becomes more common in their practices.
Area of Science:
- Tropical medicine
- Infectious disease epidemiology
Background:
- Dengue is a neglected tropical disease with increasing global incidence.
- It became a nationally notifiable disease in the US in 2009.
- Increased international travel to endemic regions poses a risk to US residents.
Purpose of the Study:
- To highlight the reemerging threat of Dengue fever in the US.
- To inform primary care physicians about the risks associated with travel to tropical and subtropical areas.
Main Methods:
- This study is a review of the current epidemiology of Dengue.
- Analysis of disease notification data in the US.
- Assessment of travel trends to Dengue-endemic regions.
Main Results:
- Dengue is reemerging globally.
- Travel to tropical and subtropical regions is the primary risk factor for US residents.
- Increased travel correlates with a higher likelihood of Dengue cases presenting in primary care.
Conclusions:
- Dengue poses a significant and growing public health risk in the US.
- Primary care physicians require increased awareness and diagnostic preparedness for Dengue.
- Public health strategies should address both disease control and traveler education.
