Older children may spread Coronavirus even faster than adults do

New research shows that families with teenage children were three times more likely to get Covid (odds of spread , 18%) than families with children under ten (5%). It appears that it’s more dangerous to live with teens than to live with adults (12%). It may be that teens are more likely to be asymptomatic which means people don’t realize they need to isolate from them.

The question of opening primary schools is potentially very different to high schools. Quite possibly puberty affects immune systems in ways that make teens effectively young adults.

Older Kids May Transmit COVID-19 as Much as Adults Do, New Evidence Shows

The results also showed up something unexpected, however. When index patients were categorised by age (0–9, 10–19, 20–29, 30–39, 40–49, 50–59, 60–69, 70–79, and >80 years), households with older children (index patients of 10–19 years) had the highest rate of infection spread to household contacts, with 18.6 percent of household contacts later showing the infection.

By contrast, young children (index patients 0–9 years of age) seemed to confer the least amount of spread of the virus, with just 5.3 percent of household contacts contracting the infection, which […]

Strap Yourself in: just three weeks from 3 patients to a hospital system on brink of collapse. 12% need intensive care.

Get out of the way of this virus.

Could Italy be suffering from a different and nastier strain?

Figures from South Korea and the Diamond Princess may not be a good guide to what’s happening in Italy and Iran. There something seriously different going on there. Death rates are much higher than expected. Three weeks ago, Italy officially had three cases, now a thousand people are dead and 12,000 have the virus. The hospital system is already at the point of being overwhelmed. Reports say that even stroke patients are now missing out on help, the ICU wards are overflowing, and the staff are prioritizing younger people because they have a better chance of survival.

Perhaps Italians hug more and spread more, perhaps it’s worse because they have an older demographic. But perhaps this is a deadlier strain than the one Japan, Hong Kong, Taiwan, Singapore and South Korea appear to be containing. The Italian strain, whatever it is, is from the Iranian strain. Every country that has imported infected passengers from Iran will likely also have the Iranian strain.

Do we really want to follow Iran and Italy?

It’s not impossible — Just stop feeding the virus fresh bodies […]
