15th August 2022 – (Hong Kong) The Hospital Authority announced earlier that a COVID-19 infected 20-month-old baby girl was diagnosed with croup during rapid antigen test. Croup is a condition caused by a viral infection such as COVID-19. Children aged 1 to 3 are at high risk. The virus leads to swelling of the voice box (larynx) and windpipe (trachea). This swelling makes the airway narrower, so it is harder to breathe. Children with croup develop a harsh, barking cough and may make a noisy, high-pitched sound when they breathe in (stridor).
According to sources, another COVID-19 infected 27-month-old boy was also diagnosed with similar croup symptoms and the young patient needed to be admitted to the Paediatric Intensive Care unit and intubated. Hoarseness is a killer of young children. It is caused by viral infection. Children aged 1 to 3 are at high risk. The patient’s throat will swell and press the trachea, hindering breathing. Generally, there are symptoms such as fever, cough, and hoarseness. Some severe patients may experience breathing Difficulty, the condition can deteriorate in a short time, and there are also deaths in Hong Kong.
During the Omicron surge, paediatricians and emergency departments began noticing something new: a surge in croup among infants and young children. Marked by a distinctive “barking” cough and sometimes noisy, high-pitched intakes of breath, croup can happen when colds and other viral infections cause the voice box, windpipe, and bronchial tubes to become inflamed and swollen. Evidence from several laboratory studies suggests that the Omicron variant mainly attacks the upper airway — the throat and bronchial tubes — whereas earlier strains mainly targeted the lungs.
