Alaska COVID-19 Count Saturday April 18, 2020 -What Numbers Say About Age

Before looking at today's numbers (and there's some good news),  I'd like to compare the State's graph on Cases by Age Group to the state's actual age group percentages.

Orange is the COVID distribution by age.
Aqua is the state's distribution by population.  I've put these #s on top of the orange chart to make it easier to compare.  Then I've marked the difference between percent of population by age in general and percent of population that tested positive.

So, COVID cases for people

• under 20 are well below their actual percent of population.
• 20-29 and 80+  are equal to their population in the state
• 30 - 69 are all above their statewide populations from +3% to +6%
• 70-79 is just +1%

So,

• Kids (under 20) are doing great as has been predicted by other rates in other countries.
• People in their 20s make up 15% of COVID cases, the same as their population
• People in their 30s make up 21% of COVID cases, making them both the highest in infection and having the greatest difference over their actual population (6%)
• People in their 40s make up 15% of COVID cases but they are only 12% of the population  
• People in their 50s are second highest ABOVE their actual population - they make up 18% of the COVID cases but only 13% of the population.
• People in their 60s are 4% above their actual population. 
• People in their 70s are just 1% above their actual population
• People 80+ are infected in the same percentage as their actual percentage of the population

I suspect that the two oldest groups are the most self-isolated groups, which, if true, would show a good correlation between isolation and getting infected.  And those in their 30s, 40s, and 50s are probably people who are most likely not isolating as effectively as they work and do essential errands.

But all these numbers are based on actual confirmed tested cases and we know that we've only tested a small percent of the population.

OK, for today's numbers.

THE GOOD NEWS
Our peak number of new cases was April 7 with 22.
Today we only had 5 new cases, the lowest number since March 30.
We've also gone 5 days now without a new death.  That's the most number of days without a new death since the first death on March 24.
