If warm weather will kill the virus

are we seeing any outbreaks now in the southern hemisphere, where it is warm?

It appears that there is one case in Brazil, in a man who had visited Italy. (http://virological.org/t/first-cases-of-coronavirus-disease-covid-19-in-brazil-south-america-2-genomes-3rd-march-2020/409)

On the other hand,

1) The Southern Hemisphere only makes up 10-12% of the global population, and since the population density is MUCH higher in the Northern Hemisphere, you'd expect to see bigger clusters of COVID-19 being reported here.

2) Testing methods are not as prevalent in many areas across the Southern Hemisphere, so there's a possibility many cases just aren't being detected.

3) Countries like Australia in the Southern Hemisphere are also struggling to limit the spread of the coronavirus. (https://www.nbc-2.com/story/41892048/will-warmer-weather-help-fight-the-coronavirus)

Has anyone read or heard anything more definite about low incidence in the southern hemisphere? And does the opposite hold true--i.e., is there a heavier incidence the colder the country is?

1. Good question. Just heard Thomas Frieden on CNN

He was former director of cdc for President Obama. He said we donít yet know about this strand and temperature and that some Coronavirus peak in the summer and others in the winter( I always thought the winter for all Coronavirus). So we are in the dark.

2. This virus is NEW. There's no evidence to support the assertion that warm weather kills it.

The truth is that we simply do not know how this virus will adapt in the coming months. If anyone tries to say they DO know, don't listen to them.

7. Keep pointing your boss to the experts - they're saying "we don't know".

Why believe someone with no expertise?? Good luck, hope your boss comes around.

12. You'll love this.

He thinks the experts are over hyping, over reacting, and making inappropriate recommendations because they are experts. This event justifies what they have worked their whole careers for, so they are too invested in making it sound worse than it is.

Along with no appreciation for what flattening the curve means or that social distancing is the only proven method of slowing transmission.

This is the mindset I am dealing with. 🤦🏼

11. I believe there is some evidence that the warmer weather

Will slow it down. They used Italy as an example where the Alpine region is hit much harder than the southern areas. Although Daegu would contradict that. I have there twice in the last 5 years and it is much hotter than Seoul.

8. Singapore is a better example.

Iran actually isn't hot right now, at least Tehran. It gets quite cold there due to elevation.

10. It gets down in the 30's and 40's for highs in the winter.

They have a spring and fall unlike many of their neighbors. I don't believe daily highs in the 50's or even 60's is high enough to kill a virus.

6. Brazil has reported 151 cases so far

It's clearly community spreading in warm regions.
