There's little chance a state like Pernambuco is anywhere as low as just 5 - 7 times undercounted, specially considering it has made the lowest number of tests relative to its population among all states. Unless, of course, they're just that accurate on determining who's infected, and that it is way more deadlier there than anywhere else in the country.

It might not be, say, 40%, but whenever the number of deaths approaches 0.1% of the population, it seems like there is a decent slowdown, and Pernambuco is sort of almost there. So I wouldn't be too concerned ATM.

8,505 positive cases (+10.3%) with 987k tests (+12.7%).

On average there were 1215 positive cases a day (or 1417 if you discard Sunday).

228 in ICU (+0.0%)

The increase in testing capacity this week was actually higher than the rise in positive cases. Positivity rate declined to 0.88%.
More and more people get infected abroad and come back sick.

#1 Kosovo - 2,528 (+44%)
#2 Croatia - 1,797 (+129%)
#3 Turkey - 1,590 (+40%)

Why Do New Disease Outbreaks Always Seem to Start in China?

The Asian Flu in 1956 killed between one and four million people worldwide. SARS in 2002 infected 8,098 and killed 774 in seventeen counties. H7N9 emerged ten years later to strike at least 1,223 people and kill four out of every ten of them. Now, the milder, yet more infectious COVID-19 has sickened more than 70,000 across the globe, resulting in 1,771 deaths.

All of these outbreaks originated in China, but why? Why is China such a hot spot for novel diseases?

Here's another:

Why So Many Epidemics Originate in Asia and Africa

The coronavirus disease, known as COVID-19, is a frightening reminder of the imminent global threat posed by emerging infectious diseases. Although epidemics have arisen during all of human history, they now seem to be on the rise. In just the past 20 years, coronaviruses alone have caused three major outbreaks worldwide. Even more troubling, the duration between these three pandemics has gotten shorter.

"Why Do New Disease Outbreaks Always Seem to Start in China?"

Is a pretty click-bait title... Which is expected from a blog I guess, either way.. Not a credible outlet, some good citations though.

I have also already established that new disease outbreaks do occur outside of China... But also hashed out why they occur more often in less developed nations. (And China is less developed.)

Don't see the point in going around in circles on this either-way.

Based on what I've read:

Chicken pox (varicella zoster virus) leads the body to build up life long immunity for almost everyone.

The flu leads to the body building up an approx 2-10 year immunity depending on the strain for almost everyone.

A cold leads to the body building up an approx 1-6 month immunity depending on the strain for almost everyone.

HIV leads to little to no immunity for almost everyone.

It's basically a scale, and depending on where the illness lands on that scale, suggests how strongly your body can combat it.

Everything I've seen says covid 19 is closer to a cold than the flu, meaning you're looking at something like a 6 month immunity tops. If it mutates, or survives and makes it way back to you, you could very well get infected again. Whether or not you get as sick as last time, if at all, remains to be seen. Your body can react much quicker however if it comes up against the same strain later on.

This is part of the reason why we don't have cold shots and why a covid 19 shot isn't that simple. If the covid shot is only good for 6 months tops, if that, then you would have to take the shot at least twice each year, if not more for it to be effective. It's tough enough to convince everyone to get one shot per year, so imagine if it's two or three.

I'm rather surprised the amount of people who've contracted it a second time isn't higher, or perhaps those individuals are having a quick enough immune response that they aren't seeing symptoms, so they don't know they've got it again. It's also possible covid 19 is a really weak strain and will just die off for good in time, so it's only impacting the weakest among us a second or third time.

Really? China is a superpower - or do you disagree?  Hell, even the rich USA has poor people. The bottom line is these viruses don't originate

in the Americas - they come from Asia and Africa - Why? Because those continents have shitty-ass sanitation standards.

China is a superpower.

But just because you are a superpower, doesn't mean you are a highly advanced, developed nation.

The reason why China has such "reach" on the world stage is due to it's sheer population... When you have 1.4~ Billion citizens you have an extremely massive work force to tap into... And even if the average yearly income is only $10,000 per capita in China verses say $67,000 in the USA, they make up for that shortfall with sheer numbers.

China is basically a zerg rush in the numbers game.

Your last part is basically parroting what I have already stated prior. Yes they do have poor sanitation standards, it's a key aspect of less developed countries.

India with 75k new cases. Yikes!

The duration of immunity might not be an issue at all if the virus mutates further into even weaker strains. Might become just as endemic and harmless as the common cold in 10 years.

I disagree. It is unimportant where it started (as pandemics like this can start anywhere in the world, also in america as it did before). But it is important how it started, what could've been done better and how to deal with it in the future. Therefore I want to see the lessons we can learn. What I don't want to do is painting the virus as a national problem, because it isn't, it is a global problem and we don't learn from seeing it as national.

About the wet markets: this is a phenomenon that developed in China, that initially started as a way to solve food problems partially for the broad population. Nowadays though it is more something for the upper middle class. As for problematicism - well, I am not sure. I think the safety in these markets could be improved at least. But as the last few infectuous outbreaks didn't came all from China, other countries can't control zoonosis even without wet markets.
