History of Zika Virus

Zika virus has no truly ancient history, as it was first identified in the mid-20th century during research on yellow fever in Africa. Scientists from the yellow fever research institute funded by the Rockefeller Foundation first isolated the Zika virus in 1947. Discovery of Zika Virus Discovery:- Scientists isolated the Zika virus in April 1947 […]

Transmission Of Zika Virus 

Transmission Of Zika Virus  Zika virus primarily circulates through a sylvatic cycle involving non-human primates and forest-dwelling Aedes mosquitoes, but human outbreaks follow an urban transmission cycle with Aedes aegypti and Aedes albopictus as key vectors. Aedes mosquitoes act as the definitive host, and humans as the amplifying host. This cycle involves an extrinsic period […]

Zika Virus Symptoms

Zika Virus Symptoms. Zika virus is primarily transmitted by Aedes mosquitoes, which bite mostly during the daytime. Most people with Zika virus infection do not develop symptoms (up to 80% of people are asymptomatic). In symptomatic cases, the illness is usually mild and self-limiting. When symptoms occur, they include mild fever, rash, conjunctivitis, muscle and […]

Key Structure of Zika Virus

Zika Virus Structure Zika virus is a mosquito-borne flavivirus that primarily spreads through bites from infected Aedes mosquitoes, such as Aedes aegypti and Aedes albopictus. It belongs to the Flaviviridae family and the Flavivirus genus. The Zika virus structure consists of a single-stranded positive-sense RNA genome enclosed in an icosahedral nucleocapsid, surrounded by a lipid […]

Laboratory Diagnosis, Treatment and Clinical Management of Zika Virus

Laboratory Diagnosis, Treatment, and Clinical Management of Zika Virus. Diagnosis Infection with Zika virus may be suspected based on symptoms of persons living in or visiting areas with higher Zika virus transmission and/or Aedes mosquito vector density. A diagnosis of Zika virus infection can only be confirmed by laboratory tests of blood or other body […]

Prevention and Control Measures for Chandipura Encephalitis

Prevention and Control Measures for Chandipura Encephalitis. Chandipura encephalitis virus (CHPV), caused by Chandipura virus and transmitted primarily by phlebotomine sandflies, has prevention focused on vector control targeting sandflies, personal protection, and public health strategies. Sandflies are easily controlled because they do not move long distances from the place of their breeding and resting sites. […]

Treatment for Chandipura Encephalitis Virus (CHPV)

Treatment For CHPV Treatment for Chandipura encephalitis virus (CHPV) infection is mainly supportive, as there is currently no specific antiviral therapy available. Supportive Care Supportive Care: Fever management using antipyretics like paracetamol to reduce high-grade fever. Hydration with intravenous fluids to prevent dehydration, especially in patients with vomiting. Seizure control using anticonvulsant medications such as […]

Clinical Characteristics of CHPV and Laboratory Diagnosis

Clinical Characteristics of CHPV and Lab Diagnosis. Chandipura encephalitis virus is characterized by a rapid onset of symptoms and severe neurological involvement, especially in children. Key differentiable signs and symptoms include high-grade fever of short duration, severe headache, vomiting, altered sensorium, generalized convulsions, and decerebrate posture, leading to grade IV coma, acute encephalitis/encephalopathy, and death […]

Vector Species Responsible for Transmission of Chandipura Virus (CHPV)

Vector Species Responsible for transmission of the Chandipura virus (CHPV) and their geographical distribution. The primary vector species responsible for transmission of Chandipura virus (CHPV) are sandflies of the genus Phlebotomus. Phlebotomus papatasi and other species are well adapted to hot, dry regions and breed in organic-rich soil, animal burrows, and human dwellings. Geographic Distribution […]
