Background: Despite advances in guidelines and treatment for pediatric asthma, child mortality due to asthma still exists. We aimed to estimate asthma mortality and morbidity and to determine whether asthma contributes to child mortality. Methods: Data on children with asthma, aged under 18, was retrieved from the Korean National Health Insurance claims database for all records between 2002 and 2015. Among them, patients who had asthma a year before death were investigated. Cause of death for all patients deceased were analyzed using data obtained from the Korean Statistical Information Service database. Cause-specific mortality was examined, and the mortality rate was compared with the general population by cause and age. Hospital use of asthma patients, including ICU admission and hospitalization, were analyzed. Results: Asthma mortality decreased from 0.09 per 100,000 children in 2003 to 0.02 per 100,000 children in 2014, with an average mortality rate of 0.06 per 100,000 children. Asthma-related mortality, defined as mortality due to respiratory diseases, also decreased significantly. Asthma-related mortality was four times more common in asthma patients compared to the general population in children older than 5. Likewise, hospitalization for asthma and intensive care in asthmatic children tended to decrease throughout the study period. Conclusions: Asthma mortality in Korea declined for asthmatic children from 2003 to 2015. Asthmatic children are at a higher risk of death from respiratory diseases compared to the general population.

Wild owls are widespread in Korea, even being common in urban areas due to the presence of hills or small mountains in and around the cities. This results in high levels of contact between owls and domestic animals. This study investigated the prevalence of avian hematozoan parasite infection in 2 common owl species in Chungbuk province of Republic of Korea for 3-year period: the Eurasian eagle owl (Bubo bubo) and the Brown hawk owl (Ninox scutulata). Peripheral blood smears taken from 56 wild owls were examined by microscopic examination and confirmed by molecular technique. Twenty (36%) of these samples tested positive for the Haemoproteus infection. The infection rate was higher in Brown hawk owls (50%) than in Eurasian eagle owls (33%). These results indicate that the wild owls may act as a reservoir for Haemoproteus infection in susceptible domestic birds.
