It could come down to a nose, or more accurately, the age of a nose, when it comes to unpicking why children seem less vulnerable to infection with SARS-CoV-2.
US researchers believe their findings on angiotensin converting enzyme 2 (ACE2) receptors in nasal passages may provide a clue for the different ways the coronavirus behaves in children and older adults.
