Most of this stuff comes from students / junior developers, where yes, they probably visit stack overflow every 20 minutes

Don't be indoors with other people.

Just look at the prior chinese coronavirus-related studies, they did antibody tests in villages near bat caves for SARS-like coronaviruses, some of villagers had antibodies in 2015 despite no reported SARS infections ever near the area.

Simplest conclusion: Zoonotic diseases sometimes jump from bats to humans in Chinese rural areas. The case clusters stay inside the isolated communities and stop naturally due to low population and lack of super-spreader events that can kickstart an epidemic.

In 2019 it happened again, but this time a villager who was infected visited Wuhan => pandemic

But for the average adult, they just do not have that many harmful bacteria or viruses randomly on their hands.

This caused some major issues with the Coronavirus. Eg. if you googled anything related to it in march, the search results displayed a "wash your hands message" even though the virus is spread by droplets AKA sharing air indoors with an infected person.

I can only imagine how many unnecessary infections and deaths this caused when people thought they were safe if they just washed their hands often. To this day, I'd say about half of the population has no clue how respitory diseases spread.

Russia is definitely a high risk area (if not THE high risk area), considering their soviet legacy of ancient nuclear power plants etc.

Spoiler: 99% chance it's from Russia.

Looks like prime batcave-like conditions for coronavirus spread.

The real reason for the fee is just to stop spammers on the App store. It probably blocks around 99% of them, without the fee I'd wager the appstore would be unusable.

Seems that people only started searching SARS in december by which the new coronavirus was already public knowledge or at least public rumor

This is a disease that is spread by breathing in air contaminated by a infected person coughing or talking.

It seems only China is being overly cautious, implementing lockdown-type measures on a Russian border city with 130 confirmed cases

Since native apps take much longer to develop and the UI toolkits are stuck in the 90s, it's pretty much given nowadays that new ones are shitty compared to the equivalent web one.

Infections happen within families, and spread from one family to another by friends/coworkers. The infected people should be easily able to list all exposed out by name.

An exception is of course mass indoors public events that are forbidden now. This is where a contact tracing app would probably prove to be the most useful.

* Being indoors during contact (increases)

* Duration of contact (every minute increases)

* Physical distance between contacts (every meter decreases)

* Amount of contacts (every person increases)

* Wearing masks (decreases)

* Washing hands (decreases)

* Coughing, speaking, singing during contacts (increases)

Meeting people close to you ticks basically every probability-increasing checkbox in the list.

1. The virus mostly spreads through BREATHING/TALKING/COUGHING.

2. 80% of infections come from FRIENDS/FAMILY. Stop going to meet them unnecessarily and spending hours together indoors.

3. Masks mostly don't help you, they help the people AROUND you.

I'd say the average person would be much better prepared against the virus with these three facts.

Somehow lots of them believe their governments are acting competently and that herd immunity is "the only way to stop the epidemic".

This virus is probably the first visible sign that Western countries have fallen from their grace, and that the Asian century has begun.

The US would probably be at over a million deaths by now if life had continued normally without lockdowns.

Your argument would basically be saying at that point "China has much more cases even though they have stricter restrictions, which means restrictions don't work!"
