Considered the most favorable periods for the proliferation of respiratory syncytial virus (RSV), because they are the coldest and driest seasons, in autumn and winter it is more frequent to observe an increase in children hospitalized for bronchiolitis and pneumonia. In this way, preventive measures and early diagnosis are tools to prevent the worsening of the clinical picture.
Belonging to the genus Pneumovirus, RSV is one of the main agents of acute respiratory tract infection. The virus reaches the bronchi and lungs. There is no vaccination against RSV. Only in the case of premature infants born up to 28 weeks of gestation or with a risk factor such as babies with bronchopulmonary dysplasia and congenital heart disease, a Ministry of Health program offers palivizumab, a specific antibody against the virus syncytial, applied once a month for five months, before the period of greatest circulation of the virus, to prevent severe forms of the disease.
Breastfeeding, for example, is an important immune booster. In other words, early weaning makes the child more fragile. Also, in the case of people who smoke, it is important to prevent the child from being exposed to smoke.
“Respiratory viruses have common symptoms such as cough, fever, sore throat and runny nose. In RSV, what catches the eye is the baby’s age – it usually affects the children up to 2 years old – and difficulty in breathing, symptoms associated with the time of year with the predominance of virus circulation Of course, there are also tests to find out which virus affects the child at this “A persistent fever and a child who does not react to stimuli are warning signs. This is true for all illnesses. Young children with respiratory problems should be evaluated by doctors”, guide Renato Kfouri , pediatrician, infectiologist and president of the Department of Immunization of the Brazilian Society of Pediatrics (SBP), during his participation yesterday in the Estadão Think Forum “Bronchiolitis and pneumonia can attack even at home – avoid your warrior d ‘have to fight the VSR’, sponsored by AstraZeneca.
In the case of bronchiolitis, children can transmit RSV for more than a week. Even after showing improvement, it is important to pay attention. Marco Aurélio Safadi, professor of pediatrics and infectiology at the Faculty of Medical Sciences of Santa Casa de São Paulo and president of the Department of Infectious Diseases of the Brazilian Society of Pediatrics (SBP), points out that in young children the risk of aggravation is greater. “A child in respiratory distress in this age group who loses the ability to breastfeed has factors taken into account in the evaluation of the clinical picture. Many cases require hospitalization to provide respiratory assistance to the baby”, specifies Safadi. “Hydration is essential in this case. And it is worth reinforcing breastfeeding in the case of the nursing baby and even increasing the supply of formula milk in the case of babies who do not suck,” explains the professor of pediatrics.
According to Rosana Richtmann, infectious disease specialist at Santa Joana Hospital and Maternity, Pro Matre Paulista and Instituto de Infectologia Emílio Ribas, premature babies are among the high-risk groups. “The finer bronchi swell and the virus causes secretions, obstructing the airways and the child is more tired,” he says.
