“…In the same study, seroprevalence of DENV antibodies were three times that of Chikungunya which agrees with the current study (Vongpunsawad et al ., 2017). In Pakistan (District Lahore), 2012, seroprevalence of Dengue in healthy individuals of age above 15 years was 67.2% in 2012 (Hafeez et al ., 2017). A study done using the residents of Qatar, it had been revealing that Asian Nationals had higher adjusted odds of being seropositive for anti-DENV and anti-CHIKV antibodies compared to nationals of Middle East, North Africa and Qatar.…”

Background: Both dengue and chikungunya are transmitted by Aedes aegypti and have many similarities in epidemiology and clinical manifestations. These two viruses are known to cause asymptomatic infection, however, studies to assess the seroprevalence in healthy individuals are limited. Our objective is to estimate the asymptomatic seroconversion status of both these infections Sri Lanka where dengue has been endemic and the last notable outbreak of chikungunya occurred in 2007. Methods: The study was performed using venous blood samples of 454 healthy individuals (age range 11-78) in Kandy district, who had no known history of dengue or chikungunya infections in the past or present. Samples were tested for dengue NS1 antigen, dengue IgM, dengue IgG, Chikungunya IgM and Chikungunya IgG by using commercially available ELISA kits. Statistical data analysis was performed using SPSS software version 16.0 (SPSS, Inc., Chicago, IL, USA). P value <0.05 was considered statistically significant. Results: Of the 454 healthy individuals, 287 (63.2%) were positive for dengue IgG indicating a past infection and 18 (4%) were positive for dengue-specific IgM. Of the same total, 82 (18.1%) were positive chikungunya chikungunya-specific IgM and only 6 (1.3%) were positive for chikungunya-specific IgM. The number of individuals positive for both dengue IgG and Chikungunya IgG, indicating dual antibody prevalence or exposure to both diseases asymptomatically was 61(13.43%). For dengue specific IgG, the highest sero-conversion rate (80.4%) was observed in 51-60 year age group whilst the lowest (50%) in the age group 11-20. Out of the MOH areas, the highest prevalence (71.4%) of positives were observed in Bambaradeniya and the lowest prevalence (53.1%) in Yatinuwara suburbs in Kandy. The highest percentage of dengue IgM prevalence (6.3%) was observed in the age group 21-30 years and the lowest percentage (1.5%) was observed in the age group 11-20. Conclusions: An asymptomatic seroconversion rate was observed in both dengue and Chikungunya infections. Dengue records a high rate due to its endemicity and periodic outbreaks. It is interesting to note the low-grade prevalence of Chikungunya infection contrary to the belief itsnon-existence in the island currently.

“…The dengue IgG antibody rate was 11.80% in Guangzhou, which was lower than in the Dominican Republic, in which it was reported that 98% of blood donors and 56% of children were positive for dengue IgG [ 16 , 17 ], and also lower than in Singapore and Pakistan, where the dengue IgG positive rate was 59% and 67.2%, respectively [ 18 , 19 ]. Because dengue infection is not considered to be endemic in Guangzhou, the incidence of infection is relatively low compared with these tropical countries which were all epidemic foci that had serious prior local outbreaks [ 14 , 20 ].…”

The majority of dengue virus infections are asymptomatic, which could potentially facilitate the transmission of dengue fever and increase the percentage of sever dengue fever manifestations. This cross-sectional study explored the sero-prevalence of dengue virus infection in Guangzhou to clarify the infection spectrum. In total, 2085 serum samples were collected from residents of 34 communities. All samples were selected from a 200,000-sample database holding serum collected from community residents living in Liwan and Yuexiu districts of Guangzhou between September 2013 and August 2015, and 17 to 28 individuals of each age group were chosen per month. Dengue immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies were tested by enzyme-linked immunosorbent assay. Symptomatic infected individuals were identified via follow-up questionnaires. Among 2085 serum samples, anti-dengue IgG and IgM positive rates were 11.80% and 3.98%, respectively. The IgG antibody positive rate increased with age and was higher in poorly educated people than in highly educated people and in married individuals than in single individuals. Approximately 96.71% of dengue virus infections and an estimated 13.68% of the whole population were asymptomatic. Such high asymptomatic-infection rates have an impact on the local spread of dengue fever. Stricter surveillance, such as a network of rapid diagnostic laboratories, screening of residents in the epidemic season, and other integrated control measures are necessary.
