Abstract

A study on acute respiratory infectious was carried out in four kindergartens in Beijing from September, 1984 to August, 1987. The results showed that ARI incidence rate in the children aged 0-7 years was 348.3%. Most of the cases were upper respiratory infectious. The incidence rate of pneumonia was 2.7%. The relationship between ARI incidence rate and age group showed that incidence of URI of 0-2 age group was 1.5 times higher than that of 5-7 age group, while the incidence of LRI of that 0-2 age group was 6.3 times higher than the later age group. The peak season of ARI was from October to January each year. The virus infections showed its priority in ARI. Duplicate samples of sera of 240 cases were tested. In which 122 cases were proved positive. Some strains of virus were isolated as well. It was showed that the influenza virus and adenovirus were the common pathogens of ARI. The effect of killed BCG(orally) on preventing ARI was observed. The preliminary date indicated the potential effect for the prevention of ARI by this measure.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
