Insights

Crimean-Congo hemorrhagic fever (CCHF), a tick-borne viral illness, was diagnosed in a child in Istanbul. Phylogenetic analysis identified a new CCHF strain, offering insights into transmission dynamics.

Area of Science:

  • * Virology
  • * Epidemiology
  • * Infectious Diseases

Background:

  • * Crimean-Congo hemorrhagic fever (CCHF) is a severe tick-borne viral disease with a wide geographic distribution, affecting human health across approximately 30 countries.
  • * The extensive range of CCHF makes it a significant public health concern, necessitating ongoing surveillance and research.

Observation:

  • * A 6-year-old boy presented with symptoms including fever, fatigue, and loss of appetite following a tick bite in rural Istanbul.
  • * Clinical examination revealed hyperemia at the tick bite site, and laboratory tests indicated elevated liver enzymes (ALT, AST), LDH, CK, and prolonged coagulation times (PT, aPTT).

Findings:

  • * Diagnostic assays, including anti-CCHF virus IgM ELISA and RT-PCR, confirmed CCHF infection.
  • * Phylogenetic analysis identified the causative agent as a novel AP92-like CCHF strain, designated KMAG-Hu-07-01 (accession number EU057975).

Implications:

  • * This case highlights the presence of CCHF in Istanbul and the potential for novel strain emergence.
  • * The detailed clinical and genetic information from this pediatric case can enhance understanding of CCHF transmission dynamics and inform public health strategies.

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...
Rocky Mountain Spotted Fever01:26

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.
Poliomyelitis01:17

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...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Yellow Fever01:18

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...
Viral Recombination00:57

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.
