Summary
Fever in patients with cutaneous larva migrans may indicate HIV infection. This finding is based on two HIV-positive cases where other fever causes were ruled out.
Area of Science:
- Dermatology
- Infectious Diseases
- Virology
Background:
- Cutaneous larva migrans (CLM) is a parasitic skin infection.
- Human Immunodeficiency Virus (HIV) infection can present with various dermatological manifestations.
- Fever is a common but non-specific symptom in immunocompromised individuals.
Observation:
- Two cases of CLM were observed in HIV-positive patients presenting with fever.
- Extensive laboratory and instrumental investigations were performed.
- Other potential causes for the fever were systematically excluded.
Findings:
- The presented cases suggest a potential association between fever and CLM in the context of HIV infection.
- CLM in HIV-positive individuals may manifest with fever, even in the absence of other opportunistic infections.
- The exclusion of alternative etiologies strengthens the link between CLM and fever in these specific cases.
Implications:
- Fever in patients diagnosed with CLM could serve as an early indicator for underlying HIV infection.
- This association warrants further investigation to understand the pathomechanisms involved.
- Clinicians should consider HIV testing in patients presenting with CLM and unexplained fever, particularly in endemic areas.

Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Yellow Fever
Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
