Last year, the bronchiolitis epidemic (viral respiratory disease that affects young children) was minimal due to health restrictions. This winter, the scenario is likely to be quite different. Indeed, the lack of immune stimulation in toddlers could have the effect of a time bomb.
Towards a larger epidemic this year?
Every year, Public Health France publishes a report winter surveillance for bronchiolitis in mainland France. In the 2020-2021 edition, the file notes that the amplitude of the epidemic was much lower than that of the previous season. ” An epidemic of greater magnitude than that observed each year is possible next year, due to the reduced immune stimulation induced by the weak circulation of the virus this winter, in a context of lifting of barrier measures. », Announces the national public health agency. As younger people are exposed to the virus, antibodies develop, which allows the body to learn how to fight different diseases more effectively. However, not all children were able to acquire this immune training last year, and therefore risk being infected this year.
A phenomenon observed in Australia
a similar phenomenon has been observed in Australia, which suffered an unusually intense outbreak in the fall of 2020. Virus activity increased from the end of September, exceeding usual figures. This year, the median age of babies with bronchiolitis in kangaroo land was 18.4 months, which is higher than the upper range monitored between 2012 and 2019.
Update on bronchiolitis
Bronchiolitis is a mild respiratory disease with major symptoms nasal congestion, mild cough, and moderate fever. There are three levels of severity of bronchiolitis: a mild form (where care is taken at home), a moderate form (where hospitalization can be done depending on the vulnerability of the toddler), and the form severe, which involves systematic hospitalization. On average, bronchiolitis affects 30% of children under the age of two. In addition, 2 to 3% of infants under one year of age are hospitalized with severe bronchiolitis.
In case of mild to moderate form, it evolves positively on its own. To relieve the baby, it is recommended to perform a nose wash regular.
