Will COVID-19 become a mostly childhood disease?
Within the next few years, as the SARS-CoV-2 virus becomes endemic in the global population, COVID-19 may behave like other common-cold coronaviruses, affecting mostly young children who have not yet been vaccinated or exposed to the virus, according to new modeling results. Because COVID-19 severity is generally lower among children, the overall burden from this disease is expected to decline.

Another common cold virus?
If it becomes endemic — circulating in the general population — and most people are exposed in childhood, SARS-CoV-2 may join the ranks of mild cold-causing coronaviruses that currently circulate in humans.

Coronavirus: How CDC Lab Contamination, And A Failure To Cooperate Globally, Led To Catastrophe
By the time the WHO chief made the above remarks, it had been almost two months since the US had identified its first case of COVID-19, the illness caused by novel coronavirus SARS-CoV-2.

Efforts to control livestock disease should focus on management style, not age
The risk of transmitting the virus PPRV, which produces a highly infectious and often fatal disease in sheep and goats, does not appear to vary significantly by an animal’s age, unlike its sibling virus measles, which is most prominent in children.

China’s control measures may have prevented 700,000 COVID-19 cases
China’s control measures during the first 50 days of the COVID-19 epidemic may have delayed the spread of the virus to cities outside of Wuhan by several days and, by interrupting transmission nationwide, prevented more than 700,000 infections across the country, according to an international team of researchers.
