The child was diagnosed with bronchopneumonia and tested positive for respiratory syncytial virus (RSV). The pediatric patient received intensive care treatment: mechanical ventilation, fluid resuscitation, chest physiotherapy, and antibiotics. After 48 hours, the child’s condition improved, respiratory parameters stabilized, and mechanical ventilation was successfully weaned.

Keeping vigil by the hospital bedside, Lò Thị May, the mother of baby T., shared that initially seeing her child sniffling, she bought cough medicine on her own to administer. Unexpectedly, after merely two nights, the baby began breathing rapidly, with wheezing sounds as if something were obstructing the throat. The previous night, the infant refused feeding and became lethargic, prompting the family to rush him to the provincial level for emergency care. Doctors noted that with any further delay, the child could have suffered life-threatening respiratory failure.

From early September to date, the provincial General Hospital has received and treated nearly 40 cases of children under 6 years old suffering from bronchitis caused by RSV infection, presenting symptoms such as coughing, fever, sneezing, rhinorrhea, and wheezing. The RSV virus is a leading pathogen causing acute respiratory tract infections in young children. A prominent biological characteristic of RSV is its potent transmission via respiratory droplets when infected individuals cough or sneeze, or through direct contact with contaminated surfaces before touching the eyes, nose, or mouth.

Upon entering the respiratory tract, RSV damages epithelial cells, increases mucus secretion, and induces airway edema and inflammation, particularly within the bronchioles. This condition can lead to airway narrowing, obstruction, wheezing, and dyspnea. This distinctive pathogenic mechanism renders young children, especially those under six months old, highly susceptible to acute respiratory distress, severe wheezing, and hazardous complications if not detected and addressed promptly.

In Điện Biên, the commencement of the new school year brings children back to classrooms, increasing physical contact and group activities, thereby facilitating community transmission of RSV-induced respiratory illnesses. Doctor Đỗ Tiến Lập, Deputy Head of the Department of Tropical Diseases at the provincial General Hospital, added that RSV is a common pathogen responsible for pediatric respiratory conditions. RSV infections can progress rapidly and turn severe, particularly in neonates, infants, and cases with underlying comorbidities. Frequently encountered complications include bronchiolitis, pneumonia, and respiratory failure.

To prevent the disease, parents should proactively bolster children’s natural immunity through balanced nutrition. For infants, exclusive breastfeeding should be sustained. Furthermore, routine handwashing with soap, cleaning toys, and limiting pediatric contact with individuals exhibiting cough or fever or in crowded environments during seasonal transitions serve as essential shields to curb virus transmission pathways.

Clinical manifestations of RSV infection are often non-specific and resemble many other respiratory infections, making differential diagnosis difficult based solely on initial signs. Consequently, when children show worsening indicators such as high fever, dyspnea, poor appetite, persistent coughing, cyanotic lips, rapid and labored breathing, or wheezing, parents must promptly take them to medical facilities for timely diagnosis and therapeutic intervention.
