Summary
Chikungunya virus (CHIKV) causes fever, rash, and joint pain. This mosquito-borne illness may be underdiagnosed in Malaysia due to its similarity to dengue, highlighting the need for better surveillance and vector control.
Area of Science:
- Medical Entomology
- Virology
- Public Health
Background:
- Chikungunya virus (CHIKV) is a mosquito-borne alphavirus causing epidemic fever, rash, and polyarthralgia in Africa and Asia.
- Two CHIKV outbreaks occurred in Malaysia (1998, 2006), but its historical presence and transmission dynamics remain unclear.
- CHIKV shares vectors (Aedes aegypti, Ae. albopictus) and symptoms with dengue, leading to potential underdiagnosis and misdiagnosis.
Purpose of the Study:
- To investigate the historical presence and potential circulation of Chikungunya virus in Malaysia.
- To understand the epidemiological context of CHIKV outbreaks in Malaysia.
- To inform public health strategies for CHIKV prevention and control.
Main Methods:
- Review of historical seroprevalence data from the 1960s.
- Analysis of reported CHIKV outbreaks in Malaysia.
- Comparison of CHIKV and dengue transmission vectors and clinical presentations.
Main Results:
- Seroprevalence studies from the 1960s suggest prior CHIKV activity in Malaysia.
- CHIKV outbreaks in 1998 and 2006 were reported, but the virus's endemicity is uncertain.
- Similarities with dengue complicate diagnosis, suggesting underreporting.
Conclusions:
- CHIKV is a significant public health concern in Malaysia, potentially circulating for decades.
- Enhanced surveillance, diagnostic capabilities, and vector control are crucial for managing CHIKV.
- Public health awareness and consideration of CHIKV in differential diagnoses are essential.

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...
01:18Yellow 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...
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...
01:17Poliomyelitis
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...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:20Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
