The southern hemisphere- warm, humid, and coming out of summer. Australia and New Zealand are both close to China geographically, and would certainly have had coronavirus that same time other countries did. How badly did countries in the Southern Hemisphere get hit by COVID-19?
These are deaths per 1 million citizens:
3- Australia
4- New Zealand
For comparison-
170- United States
503- Spain
446- Italy
357- France
622- Belgium
225- Sweden
Generally around
100x less deaths per capita in the midst of a pandemic. The trend is across the board for countries below the equator, many of which have high density populations and poor healthcare.
There seems to be some significant empirical data that suggests warmth and humidity will suppress coronavirus.
Could Jason Beaubien, a scientist from the Department of Homeland Security (United States), be misleading us again? In his interview, he leads us to believe that summer is unlikely to have an effect on the spread of coronavirus.
Jason quotes-
Bill Bryan, the science and technology adviser at the Department of Homeland Security, at that briefing last night, he called - he said it would be irresponsible to say that summer is going to totally kill this virus.
Masterful wordplay, nobody is suggesting that summer would totally kill the virus. But yet he is saying the unnamed experts do not think summer will inhibit coronavirus.
The empirical data disagrees. IMO.
DAVID GREENE, HOST:
At a briefing last night at the White House, a scientist from the Department of Homeland Security unveiled some preliminary research suggesting that heat and humidity kill the coronavirus. From there, the briefing got a little strange, with President Trump suggesting that ultraviolet light or injected bleach may work as well. I want to bring in NPR's global health and development correspondent Jason Beaubien. Hi, Jason.
JASON BEAUBIEN, BYLINE: Hey. Good morning.
GREENE: Let's start with these suggestions about heat and humidity. I mean, could this mean - this is a question we've been asking for a while now...
BEAUBIEN: Yeah.
GREENE: ...Could it mean that this will be like the seasonal flu and it'll go away when it gets warm?
BEAUBIEN: You know, so - first, the seasonality of the flu, it's a really complicated dance that has to do with a lot of things. Like, it's got human patterns of behavior, people being cooped up in the winter, the number of people who are susceptible any given winter to a particular strain of the flu. You know - and there is some evidence out there that flu viruses spread more easily in colder temperatures. It's got to do with the relative humidity of the air going down as the temperature drops, and then there's less moisture in the air and these respiratory viruses move through the air more easily.
However - and I've talked to a lot of flu researchers on this, and they say in the first year that a new virus is circulating, it's very unlikely that you would get that pattern in part because there's this huge pool of people who have no immunity to this particular virus. And that gives the virus fertile ground to spread in a way that would outweigh any marginal benefit that it would have, you know - the suppression of it might be due to that rise in temperature. And even Bill Bryan, the science and technology adviser at the Department of Homeland Security, at that briefing last night, he called - he said it would be irresponsible to say that summer is going to totally kill this virus.
