| sequences of e/ns1 gene junction from four dengue-2 viruses of northeastern thailand and their evolutionary relationships with other dengue-2 viruses. | we determined the 240-nucleotide sequences of the e/ns1 gene junction of four dengue-2 viruses by the primer extension dideoxy chain termination method. these viruses were isolated from dengue patients with different clinical severities in nakhon phanom, northeastern thailand in 1993. the results were compared with the 52 published dengue-2 sequences of the same gene region. sequence divergence of four new isolates varied from 4.17% to 5.42% compared with dengue-2 prototype new guinea c strain w ... | 1995 | 7494497 |
| weather factors influencing the occurrence of dengue fever in nakhon si thammarat, thailand. | this study explored the impact of weather variability on the transmission of dengue fever in nakhon si thammarat, thailand. data on monthly-notified cases of dengue fever, over the period of january 1981 - june 2012 were collected from the bureau of epidemiology, department of disease control, ministry of public health. weather data over the same period were obtained from the thai meteorological department. spearman correlation analysis and time-series adjusted poisson regression analysis were p ... | 2013 | 24522133 |
| monthly district level risk of dengue occurrences in sakon nakhon province, thailand. | the paper deals with the incidence of the dengue virus infection (dvi) in the 18 districts of sakon nakhon province, thailand, from january 2005 to december 2007. using a statistical and autoregressive analysis to smooth incidence data, we have constructed yearly and monthly district level maps of the dvi distribution. it is found that the dvi incidence is very correlated with weather conditions and higher occurrences are observed in the three most populated districts wanon niwat, sawang daen di ... | 2010 | 20817262 |
| silent transmission of virus during a dengue epidemic, nakhon pathom province, thailand 2001. | in the year 2001 a large dengue fever (df)/dengue hemorrhagic fever (dhf) outbreak occurred in nakhon pathom province, thailand. three thousand one hundred twelve cases of dhf were reported, an attack rate of 393 per 100,000 population. the nakhon pathom provincial health office immediately carried out a control action according to who recommendations. active serological surveys and viral rna isolation were carried out to detect silent transmission of dengue virus in 329 healthy volunteers in na ... | 2006 | 17333731 |
| sequences of terminal non-coding regions from four dengue-2 viruses isolated from patients exhibiting different disease severities. | we have determined the 5' and 3' non-coding regions (ncr) of four dengue-2 viruses isolated from dengue patients with different clinical severities in nakhon phanom, northeastern thailand in 1993. the results were compared to prototype dengue-2 strains and were found to have highest homology with the new guinea c strain. the sequence of the 5' ncr was completely conserved among all 4 isolates and were identical to the sequence of the new guinea c strain. homology of the 3' ncr sequence of the fo ... | 1997 | 9208450 |
| epidemiology and control of dengue virus infections in thai villages in 1987. | a severe epidemic of dengue hemorrhagic fever (dhf) in nakhon ratchasima, thailand in august of 1987 prompted a field investigation. dhf rates of 0.4-6.5 cases per 1,000 residents in subdistricts and 2-15 cases per 1,000 residents in 10 villages investigated were reported. epidemics peaked in neighboring villages at different times; in june and july, and in august before the rainy season began late in the month. in 4 primary schools representing 6 villages, sera from groups of randomly selected ... | 1989 | 2764233 |
