From the Guidelines
Mosquito-borne illnesses like malaria and dengue fever require prompt diagnosis and specific treatments based on the causative pathogen. Malaria is diagnosed through blood smears or rapid diagnostic tests that detect Plasmodium parasites, while dengue is diagnosed using serological tests that identify viral antigens or antibodies.
Diagnosis and Treatment
- Malaria treatment: artemisinin-based combination therapies (ACTs) are the standard first-line treatment, with regimens like artemether-lumefantrine (Coartem) taken twice daily for three days 1.
- Severe malaria requires intravenous artesunate or quinine.
- Chloroquine may still be used in areas without resistance.
- Dengue fever has no specific antiviral treatment and is managed supportively with rest, adequate hydration, and acetaminophen for fever and pain (avoiding NSAIDs like ibuprofen due to bleeding risk) 1.
Prevention
- Using insect repellents containing DEET,
- Wearing protective clothing,
- Using bed nets,
- Eliminating mosquito breeding sites 1. Early treatment is essential as both diseases can progress to life-threatening conditions if not properly managed, with malaria causing organ failure and dengue potentially developing into hemorrhagic fever or shock syndrome. Prevention measures should be taken seriously, especially during peak biting hours of mosquitoes, to minimize the risk of transmission 1.

From the Research
Mosquito-Borne Illnesses
- Malaria is a mosquito-borne illness caused by protozoa parasites of the genus Plasmodium, with approximately 2000 cases diagnosed in the US each year, mostly in travelers returning from endemic areas 2.
- Dengue fever is another mosquito-borne illness, but the provided studies do not directly address its diagnosis and treatment.
Diagnosis and Treatment of Malaria
- Malaria is diagnosed based on the presence of Plasmodium parasites in the blood, with different species requiring different treatments 2.
- The first-line therapy for P falciparum malaria in the US is combination therapy that includes artemisinin, while chloroquine is an alternative option for chloroquine-sensitive regions 2.
- For severe malaria, intravenous artesunate is the first-line therapy, and treatment of mild malaria due to a chloroquine-resistant parasite consists of a combination therapy that includes artemisinin or chloroquine for chloroquine-sensitive malaria 2.
Mosquito Syndrome
- There is no direct mention of "mosquito syndrome" in the provided studies, but they discuss exaggerated skin reactions to mosquito bites, which can be associated with rare hematological disorders, abnormalities in eosinophils, and/or association with Epstein-Barr virus (EBV) 3.
- Hypersensitivity to mosquito bites (HMB) is characterized by necrotic skin reactions to mosquito bites with various systemic symptoms, often observed in association with EBV infection and natural killer (NK) cell lymphoproliferative disorder 3.
Treatment of Exaggerated Skin Reactions to Mosquito Bites
- The treatment of exaggerated skin reactions to mosquito bites is not directly addressed in the provided studies, but they discuss the pathophysiology and association with various hematological disorders 3.
- Artemisinin and its derivatives have been investigated for their potential use in treating respiratory diseases, including inflammatory-driven respiratory disorders, due to their anti-inflammatory and anti-viral properties 4.
