Chikungunya Fever Outbreak, Zhejiang Province, China, 2017
Emerging Infectious Diseases
|July 17, 2019
Summary
A chikungunya virus outbreak occurred in China in 2017. The virus strain was identified as originating from Bangladesh, highlighting the risk of imported infectious diseases.
Area of Science:
- Epidemiology
- Virology
- Public Health
Background:
- Chikungunya virus (CHIKV) poses a significant global health threat, causing outbreaks with potential for widespread transmission.
- Understanding the genetic diversity and origins of CHIKV strains is crucial for effective disease surveillance and control.
Observation:
- A chikungunya virus disease outbreak was documented in Zhejiang Province, China, during August 2017.
- This event marked a notable occurrence of chikungunya in the region.
Findings:
- Phylogenetic analysis revealed the causative CHIKV strain belongs to the Indian Ocean clade of the East/Central/South African genotype.
- The outbreak was linked to an imported case, with the virus introduced by a traveler returning from Bangladesh.
Implications:
- This finding underscores the importance of robust border health screening and surveillance systems to prevent the introduction and spread of arboviruses.
- The genetic characterization provides valuable data for tracking CHIKV evolution and geographical dissemination.
- Public health strategies must consider the potential for CHIKV importation and local transmission in non-endemic areas.

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
