Australian researchers report about a family in which the parents were Covid positive, but their children repeatedly tested negative & showed robust immune response.
The survey, conducted across 700 villages, also estimated that one in 15 individuals aged more than 10 years was estimated to have been infected in August.
The study focused on 91 paediatric Covid patients from 22 hospitals. The children were tested every 3 days on an average to understand how long virus shedding continues.
The study, published in the journal JAMA Internal Medicine, is also among the first few to academically distinguish between pre-symptomatic and asymptomatic patients.

WHO has issued a new 10-page brief on Covid transmission after over 200 scientists wrote an open letter asking for revision of airborne transmission advisories.
