Các loại virus hay gây viêm phổi ở

Các loại virus hay gây viêm phổi ở trẻ em bao gồm virus hợp bào hô hấp (respiratory syncytial virus-RSV), parainfluenza, influenza, and adenoviruses. Trong đó RSV là tác nhân hay gây viêm phổi nhất, đặc biệt là ở các trẻ nhỏ.
Dịch tễ học
Nhiễm khuẩn hô hấp cấp tính là bệnh lý phổ biến nhất trong bệnh lý nhi khoa. Tuy viêm phổi chỉ chiếm 10-15 % các trường hợp nhiễm khuẩn hô hấp cấp tính, nhưng lại gây một tỷ lệ tử vong đáng kể. Theo UNICEF, hằng năm trên toàn thế giới có khoảng 3 triệu trẻ chết vì viêm phổi. Tuy đa số các trường hợp tử vong xảy ra ở những nước đang phát triển, nhưng viêm phổi vẫn là nguyên nhân gây tử vong chủ yếu ở những nước đã phát triển. Trong các nghiên cứu ở cộng đồng, tỷ lệ mắc viêm phổi hằng năm khoảng 4/100 trẻ trước tuổi đi học. 2/100 trẻ tuổi từ 5-9, và 1/100 trẻ tuổi từ 9-15 tuổi. Viêm phổi, nếu được phát hiện sớm nhờ X quang, chiếm 7,5% các trường hợp sốt ở trẻ

The type of virus or cause pneumonia in children included respiratory cell combined virus (RSV respiratory syncytial virus-), parainfluenza, influenza, and adenoviruses. In that RSV is the agent or cause inflammation of the lungs, especially in young children.EpidemiologyAcute respiratory infections are the most common diseases in pediatric pathology. While pneumonia accounted for only 10-15% of cases of acute respiratory infections, but causes a significant mortality. According to UNICEF, every year around the world there are about 3 million children die of pneumonia. While the majority of the deaths occur in the developing countries, but pneumonia still the principal cause of death in the developed countries. In studies in the community, the incidence of pneumonia annually about 4 per 100 children before school age. 2/100 youth from 5-9, and 1/100 infants aged 6-15 years old. Pneumonia, if detected early thanks to radiology, accounting for 7.5% of the cases of fever in older < 3 months, and 13% of the infections in the first two years.In developed countries, in groups of pneumonia caused by the virus microorganisms occupies the top position, followed by m. pneumoniae and bacteria such as s. pneumoniae, Haemophilus influenzae type b and Staphylococcus aureus. In the developing countries like our country, pneumonia due to bacteria occupy a more important position.Viral pneumonia occurs with the highest frequency in the ages 2-3 years, then decrease gradually. Most seasons are in winter (cold and humid). The form and the level of severity of pneumonia caused by the virus varies according to a number of factors such as age, season, signed the host's immune status and factors related to the environment for example where in the crowded, cramped.

of acute respiratory infections are the most common diseases in pediatric pathology. Although pneumonia accounted for 10-15% of cases of acute respiratory infections, but cause a significant mortality rate. According to UNICEF, every year around the world there are about 3 million children die from pneumonia. Although the majority of these deaths occur in developing countries, but pneumonia is still the cause of death mainly in the developed countries. In community studies, the incidence of pneumonia every year approximately 4/100 preschool children. 2/100 children, ages 5-9, and children aged 9-15 years old 1/100. Pneumonia, if detected early thanks to X-rays, accounting for 7.5% of cases of fever in infants <3 months, and 13% of infections in the first two years.
In developing countries, pneumonia group microorganisms, the virus occupies the top spot, followed by M. pneumoniae and S. pneumoniae bacteria such as, Haemophilus influenzae type b and Staphylococcus aureus. In developing countries such as Vietnam, pneumonia bacteria occupy important positions than viruses.
Pneumonia virus occurred with the highest incidence in the age group 2-3 years, then decrease. Season is most common in winter (cold and wet). Morphology and severity of viral pneumonia vary according to several factors such as age, season, immune status of the host and the factors related to the environment eg in crowded places, cramped.
