A new SARS-Cov-2 coronavirus infection associated with respiratory syncytial virus in a child of the first month of life

The article presents a clinical case of a combined course of a new coronavirus (SARS-CoV-2) and respiratory syncytial virus (RSV) infections in a young child with congenital heart disease. The disease began typically, with moderately severe catarrhal phenomena and intoxication. The deterioration of the child's condition was noted by the 3rd day from the onset of the disease, and was associated with the development of pneumonia and severe respiratory failure. The disease progressed with an increase in lung tissue damage and the appearance of multiple organ pathologies (cardiovascular, digestive, urinary, nervous system). 
On the example of this clinical case, it was revealed that the new SARS-CoV-2 infection associated with RSV infection in a young child had a severe course accompanied by multiple organ failure, which was aggravated by the patient's comorbidity (congenital heart disease) and an unfavorable premorbid condition. Despite the extremely difficult course, the case ended happily. 
Given the risk of developing mixed infections in newborns, the vigilance of a pediatrician, constant dynamic monitoring and preventive measures aimed at preventing the occurrence of complications in such children are important.
