“…High preference of An. stephensi to AB group might increase malaria infection and fatality in this blood group and resulted in low frequency of AB group in the residents of malaria endemic areas, suggesting that malaria vectors, like parasites may have selection pressure on human genotypes (15) .…”

Abstract:Introduction: There is a paucity of studies on the relationship between ABO blood group and its influence on malarial infection. This study was undertaken to study the relationship of severity of malaria with blood groups and to evaluate if ABO blood groups show differential susceptibility to falciparummalaria. Methods: In 200 malaria positive patients, blood group analysis was done. Patients with at least one of the following complications was considered complicated malaria cases, ie: cerebral malaria, severe anemia, circulatory collapse, jaundice, hematuria, bleeding manifestations, acute respiratory distress syndrome, and death. Results: Vivax malaria (75.5%) and blood group O (43%) were the commonest amongst the cases. No significant relationship was present between blood groups and type of infection, parasite load vs blood groups, and complicated cases vs parasite load. Uncomplicated (62%) cases were more than complicated (31%) cases. Blood group O dominated among complicated (37.9%) and uncomplicated (45.65%) cases. No signifiant correlation was present between blood groups and distribution of complicated cases, and between complicated falciparum cases and blood groups. Seven cases of mixed malaria had blood group A and O. Among A blood group, 57.1% of the mixed malaria cases had complications, whereas in O blood group only 14.3% had complications. There was a statistically significant relation between complicated mixed malaria cases and blood groups, with blood group A being more prone to complications. (X 2 =15.131; P=0.019). Conclusions: Blood group O was the dominant blood type in both complicated and uncomplicated malaria cases. Blood group A cases were more prone to severe mixed malaria infections while, blood group O had a favorable clinical outcome.

Travel frequency of people varies widely with occupation, age, gender, ethnicity, income, climate and other factors. Meanwhile, the distribution of the numbers of times people in different regions or with different travel behaviors bitten by mosquitoes may be nonuniform. To reflect these two heterogeneities, we develop a multipatch model to study the impact of travel frequency and human biting rate on the spatial spread of mosquito-borne diseases. The human population in each patch is divided into four classes: susceptible unfrequent, infectious unfrequent, susceptible frequent, and infectious frequent. The basic reproduction number R 0 is defined. It is shown that the diseasefree equilibrium is globally asymptotically stable if R 0 ≤ 1, and there is a unique endemic equilibrium that is globally asymptotically stable if R 0 > 1. A more detailed study is conducted on the single patch model. We use analytical and numerical methods to demonstrate that the model without considering the difference of humans in travel frequency mostly underestimates the risk of infection. Numerical simulations suggest that the greater the difference in travel frequency, the larger the underestimate of the transmission potential. In addition, the basic reproduction number R 0 may decreasingly, or increasingly, or nonmonotonically vary when more people travel frequently.

BACKGROUND Mosquitoes express different degrees of preference towards hosts depending on behavioral, ecological, and physiological factors. These preferences have implications for mosquito‐borne disease risk. This study investigated the effect of human blood groups on the behavior and fecundity of the female Aedes aegypti (Diptera: Culicidae) from March 2018 to August 2019. In laboratory tests, mosquitoes were fed artificial membrane feeders on A, AB, B, and O blood groups. The level of attraction to different blood groups was tested under controlled conditions with a wind tunnel bioassay. RESULTS The responses of Ae. aegypti to the blood groups treatments in the five‐choice tunnel chambers showed a significant preference (Kruskal‐Wallis (2 = 85.772, df = 4, P < 0.0001) for favor blood group B. Also, the response of Ae. aegypti to olfactory cues (filth) derived from a pool of volunteers cutting across the blood groups showed a similar preference for pattern towards the blood group B. The percentage rate of digestibility in Ae. aegypti was highest in those fed on blood group O, while individuals fed on the AB blood group had the lowest digestion rate. Thus, the rate of digestibility highly varied significantly (P < 0.0001) between blood groups. Overall, Ae. aegypti fed on blood group B had the highest average feeding rate, number of females with eggs, and fecundity level, which showed a significant difference (P < 0.0001) on preferred. CONCLUSION This study provides novel insight into the ABO host choice of Ae. aegypti and reinforces the need for personal protection against dengue virus transmission in light of the increased risk of exposure for individuals with B blood type. © 2021 Society of Chemical Industry.
