Article Synopsis
  • Mumps outbreaks have been increasingly reported globally, including in vaccinated populations, prompting a study on the epidemic's characteristics in Wuhan from 2005 to 2019.
  • The study analyzed 40,685 mumps cases, revealing a fluctuating morbidity rate with significant peaks every few years and highlighted a bimodal seasonal pattern, predominantly affecting male children aged 5-9.
  • Findings indicated spatial clusters of high cases primarily in the western and southern regions of Wuhan, helping public health officials improve targeted health strategies and resource allocation.

Cyclists can be easily exposed to traffic-related pollutants due to riding on or close to the road during commuting in cities. PM has been identified as one of the major pollutants emitted by vehicles and associated with cardiopulmonary and respiratory diseases. As routing has been suggested to reduce the exposures for cyclists, in this study, PM was monitored with low-cost sensors during commuting periods to develop models for identifying low exposure routes in three Asian cities: Taipei, Osaka, and Seoul.

Article Synopsis
  • * Researchers developed a seasonal ARIMA model to analyze 84 months of HFMD data (2009-2015) for forecasting future incidences, which showed effective predictions with clear pattern recognition.
  • * The identified optimal ARIMA model (1,0,1)(0,1,1) demonstrated strong predictive capabilities, highlighting two peaks of HFMD activity in mid-year and late-year, and emphasizes the need for continual updates to the model for improved future forecasts.

Objective: To identify the risk factors for reported sudden rise of measles incidence in November, 2011, in some areas of Hubei province.

Methods: We analyzed all measles patients reported in the measles surveillance system from November 2011 to February 2012 in two prefectures with highest attack rates and their vaccination history by reviewing vaccination records. We interviewed patients' parents by telephone to obtain the history of visiting health care within 7 to 21 days before onset.

Article Synopsis
  • * A total of 78 environmental samples from wild bird habitats and urban poultry markets were collected, along with 249 serum samples from local residents and workers; various testing methods helped identify positive influenza A samples and specific subtypes.
  • * Results indicated that 34% of live poultry market samples tested positive for influenza A, including several subtypes (H5, H9, H3), whereas all samples from migratory bird habitats were negative; additionally, 40.2% of serum samples showed significant levels of H5

Objective: To analyze the molecular characteristics of the newly isolated two Japanese encephalitis virus strains (JEV) in Wuhan.

Methods: The mosquitoes were collected in Wuhan from April to October in 2009. The envelope (E) protein gene of JEV was detected using RT-PCR and sequenced.

To discuss the effects on early warning of measles, using the neural networks. Based on the available data through monthly and weekly reports on measles from January 1986 to August 2006 in Wuhan city. The modal was developed using the neural networks to predict and analyze the prevalence and incidence of measles.
