5/n Taken together, the data indicate that BA.3.2 can cause COVID-19 disease burden in young children. This age group appears particularly vulnerable because of lack of BA.3.2-neutralizing antibodies, see recent manuscript from @yunlong_cao ➡️Continued BA.3.2 circulation 7.4K views · 37 likes · 8 reposts · 3 replies Open on X →

3/n In New Zealand, BA.3.2 frequencies approaching 50% during April and May 2026 were accompanied by a marked increase in hospitalizations for severe acute respiratory infection (SARI) in children aged 0–4 years, while other age groups showed no comparable increase. 979 views · 27 likes · 7 reposts · 2 replies Open on X →

4/n A note on the New Zealand data: Only a minority of SARI patients tested positive for SARS-CoV-2, although positive cases were concentrated in the 0–4 age group.

2/n A shift in COVID-19 case distribution from older adults toward very young children became apparent in Australia during the last quarter of 2025.
