Summary
Chikungunya virus autochthonous transmission occurred in France in 2010, facilitated by the Aedes albopictus mosquito. Viral genome analysis revealed novel features suggesting potential European emergence and spread.
Area of Science:
- Virology
- Epidemiology
- Medical Entomology
Background:
- Chikungunya virus (CHIKV) is a mosquito-borne alphavirus causing febrile illness.
- Autochthonous transmission signifies local virus spread, not imported cases.
- The presence of Aedes albopictus mosquitoes in Europe poses a risk for CHIKV introduction and transmission.
Purpose of the Study:
- To report the first autochthonous transmission of chikungunya virus in southeastern France.
- To analyze the genetic characteristics of locally transmitted CHIKV strains.
- To assess the implications of these findings for CHIKV emergence in Europe.
Main Methods:
- Surveillance for CHIKV infections in southeastern France.
- Mosquito vector identification and distribution assessment.
- Viral genome sequencing and phylogenetic analysis of CHIKV isolates.
Main Results:
- Confirmed autochthonous CHIKV transmission in September 2010.
- Identified Aedes albopictus as the likely local vector.
- Sequence analysis revealed specific viral genome features in local isolates.
Conclusions:
- The 2010 CHIKV outbreak in France demonstrates local transmission potential.
- Genetic features of the virus may influence its adaptation and spread in European environments.
- Ongoing surveillance is crucial to monitor CHIKV emergence in non-endemic regions.

Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
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...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
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.
Viral Recombination
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
