National Health and Health Commission released a message that since 2019, children with adenovirus pneumonia in some parts of the country have increased in different degrees compared with previous years, and pointed out that human adenovirus (HAdV) pneumonia is a serious problem in children’s community-acquired pneumonia. One of the types, mostly in children from 6 months to 5 years old, especially children under 2 years old. Some children have severe clinical manifestations and many extrapulmonary complications. Chronic airway and lung diseases are easily left in severe cases. It is one of the important causes of death and disability of infants and young children. It needs high attention.
Most of the symptoms of adenovirus infection are mild, with one or two inpatients per 100 children. Mr Segun, deputy director of the Pediatrics Department of Pediatric People’s Hospital in Lagos, said that adenovirus is a common pathogen that can cause infection and morbidity in humans. In most cases, the symptoms are lighter and can heal itself, and there is no obvious seasonal difference.
”It is estimated that one out of every 100 child hospitalized patients will be infected with adenovirus.” Segun said, but basically the symptoms are relatively mild, and few patients with severe disease. But medically, individual cases can be severe and critical, or even die. Especially in patients with immunodeficiency or chronic respiratory diseases, heart disease, etc., the risk of causing serious diseases after infection with adenovirus is high. In general, Mr Segun said that in general, the mortality rate of critically ill patients is relatively high, and the mortality rate of some severely ill patients has reached 30%-40%. However, in places with good medical conditions, some deaths are only 10%.
The symptoms of adenovirus infection are similar to the flu, but there is no specific drug. Due to the different tissue tropism of different adenoviruses, adenovirus infection can lead to a variety of clinical manifestations and diseases, including respiratory diseases (such as common cold, bronchitis, pneumonia, etc.), digestive tract diseases (such as diarrhea, gastroenteritis, etc.) ), conjunctivitis, cystitis, and nervous system diseases.
”Continuous fever, cough, wheezing, etc. are the most obvious symptoms of adenovirus infection.” Mr Segun said, but because the clinical manifestations of adenovirus infection in the early stage are not obvious (similar to the common cold), many parents because of neglect of the disease, and the early diagnosis rate is not high, resulting in delays in optimal treatment time.
”And the adenovirus infection is different from the flu, the flu has a specific drug, but the adenovirus has no specific drug to use.” Mr Segun stressed that this is also an important reason for the high mortality rate of patients with severe adenovirus infection.
Mr Segun said that people of all ages may be infected with human adenovirus, but the age group is mainly concentrated between months and 5 years old. In particular, patients with underlying diseases such as immunocompromised, chronic respiratory diseases, and heart disease have a higher risk of causing serious illness after infection. He said that the high fever of adenovirus can last for 1-2 weeks, and it is relatively serious if it causes pneumonia. The damage to the lungs will be more serious, and some may even have sequelae.
In fact, adenovirus is contagious, mainly in confined, crowded and humid environments, such as military camps, schools, child care institutions, hospitals, etc., should pay attention to strengthen prevention and control.
Wear a mask and wash your hands to prevent adenovirus infection. How do I know if a child has been “attacked” by an adenovirus? The correct method of diagnosis is to go to a regular hospital in time, and the hospital can detect it through a nasopharyngeal swab.
Mr Segun said that droplet spread is the main mode of transmission of adenovirus, such as coughing or sneezing, followed by contact, such as contact with adenovirus-contaminated objects or surfaces, unwashed mouth, nose or eyes; The digestive tract spreads and the adenovirus can spread through the feces of the infected person, such as during diaper replacement.
Mr Segun suggested that the main means of preventing human adenovirus infection include wearing a mask, washing hands frequently, avoiding touching the eyes, nose and mouth with unclean hands, avoiding close contact with patients, especially wearing masks in crowded places such as public places. .
Once infected with human adenovirus, Mr Segun recommends that those with mild symptoms should be separated from home and avoid going to public places. In the event of persistent high fever, cough, shortness of breath and other serious symptoms, you should go to the hospital in time, and severe cases require hospitalization. (sensitive)
