|February 13, 2009
Summary
Chikungunya virus re-emerged in West Bengal, causing an epidemic with fever, joint pain, and rashes in over 40% of investigated patients. This outbreak followed a four-decade absence of the virus in the region.
Area of Science:
- Epidemiology
- Infectious Diseases
- Virology
Background:
- An outbreak of fever of unknown origin occurred in West Bengal between August and December 2007.
- Cases presented with high fever, prolonged joint pain, and skin rashes.
Discussion:
- A serological survey identified Chikungunya virus antibodies in 40.13% of 800 investigated patients.
- The predominant symptoms were fever (100%), arthralgia (96%), and skin rash (94%).
- Hemorrhagic manifestations were observed in 3% of cases.
Key Insights:
- Chikungunya virus re-emerged in epidemic form in West Bengal after a 40-year gap.
- The study confirmed a significant seroprevalence of Chikungunya in the affected districts.
- The clinical presentation aligns with known Chikungunya symptoms, with a notable incidence of arthralgia.
Outlook:
- Further research is needed to understand the long-term sequelae of this Chikungunya outbreak.
- Enhanced surveillance and vector control strategies are crucial to prevent future epidemics.
- Understanding the genetic characteristics of the re-emerged virus may inform public health responses.

01:25Arboviral 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...
01:29Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:18Yellow 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...
