Can restricting the flow of people across national borders stop a new pathogen from causing a pandemic in a world of 8 billion people?

and nine deaths linked to the virus, unrelated to recent travel outside of the US.

, and my research focuses primarily on infectious disease and how our culture and history is shaped by disease transmission in populations. My recent research provides some insight into how well screening efforts work.Many countries are screening passengers at airports with limited success. Despite improved technology in the past decade, passengers who are incubating a disease and have no clinical signs or symptoms may pass through the checkpoints undetected.

There are many studies that have taken a retrospective look at the success of using entry/exit screenings. One of the most recent points-of-entry screenings was used in an attempt to slow the spread of Ebola from western Africa in 2014. In that situation, more thanin the three countries where the epidemic emerged. No cases were detected, yet four cases actually were exported. Those individuals had no symptoms at the time of screening.

No it doesn't they should stop saying things are under control wherelse they aren't.....

That is just a facade & nothing more if it did then why are only coming to know of those infected when they already are at home, how did they passed the entry points?

The virus might show signs after a few days only. Everyone should self quarantine for a few days to make sure they don't have it.

I don't think it really works.

Yes!!! Stop pretending to be know alls with your quasi intellectual questions!

Why not just ban travel.

I flew to Nelspruit today. No screening anywhere. Only the ticket controller had face mask and gloves. In the plane a guy with face mask wanted to sit next to me. I asked if he is sick and if he came from China or Italy. He moved on and chose another seat.

It clearly doesn't. We have evidence

They don’t need to test temperature, but everything, possible to get an accurate result. But temperature won’t help at anything

I starting to doubt that now...

I feel like WHO standards are for the rich...self isolation 🙄 if I were to self isolate where am I going to isolate myself in a 3 room house🤨

No

Nope it doesn’t ...all people traveling from outside of Africa must be quarantined for 21days irrespective if whether they are symptomatic or not. Not self isolation...what happens when you “self isolate” when you have a family Staying with you?Really do you have your own kitchen

This question is the joke of the year.

Can South African government ban people to come in mare yooh 😭😭😭😭😭😭💔 kore this government doesn't care yoh I guess they will care once their is death toll

Other countries don't want to know whether they can manage the virus or not.Why is our country feels it should see if it can or not.

It's spreading, so I doubt it.... 🙄

No

No it doesn't work it's a joke

Clearly not 24 case from 7 in one week do the math it's getting worse

Obviously not

⚠️ I don't think so. The following symptoms may appear only after 2-14 days after exposure. Fever, Cough, Shortness of breath.

Yes at the moment because all those that tested positive were captured at the airport

Cha

Their clothes/luggage might be having this virus attached to them...

No. Its not working

It doesn't work.

It doesn’t work

The answer is NO! How did they get in with the Virus if it was working?
