warm temperatures, high humidity, and breezy conditions? You know, like at a beach or playground?
Fantastic summary.Moxley said:
Theoretically, humidity will prevent droplets from flying as far and wind will spread them out. UV light will sanitize over time. So it seems likely the risk of spread would be much less at a beach so long as people stay out of each other's business.
That being said, big drunken beach parties like at spring break are probably cesspools of viral spread due to extended close contact.
How close do you get to people at the beach for any extended time that would pose any threat of spreading the virus under the conditions specified?Moxley said:

You assume it spread on the beach rather than in hotels, nightclubs, and restaurants. The same with the Panama example. The Panama example says nothing. Do people there stay outside all the time? Was it in families? Crowded homes or indoor public places?FlyRod said:
Yes. A study was just published showing how returning Spring Breakers not only increased transmission, but mortality rates too. I will find it when I can and link it here as an

If you believe this then we should see a huge spike in Galveston/Brazoria/Harris counties next week. They had Jeep Weekend last Saturday. All of the Houston news stations covered it.Moxley said:

Note the word "minutes"? If you are standing outside and cough in someone's face, it isn't going to take minutes for the viruses to travel through the air and into their face.Quote:
"What we have found so far is that sunlight seems to be very detrimental to the virus," Dabisch explained. "And so within minutes, the majority of the virus is inactivated on surfaces and in the air in direct sunlight."

Here is the more detailed data on Panama. In Spanish but fairly easy to follow. We got our first case here on March 8th.
In terms of spread the past couple of months, all beaches and public parks have been closed, and the population has been completely locked down with very restricted movement. Presumably most of this particular spread That occurred was in workplaces, homes, grocery stores, etc.Though a bunch of folks did also blow off the quarantines early on doing 'quarantine parties' until there was a stronger crackdown.
Panama is now starting to gradually reopen up in mid-May.
So it appears the spread occurs mainly indoors or outside in cold weather. Outside when it is hot and the UV rays are strong there is little evidencie of spread.

The seasonality of influenza viruses and endemic human coronaviruses was tracked over an 8-year period to assess key epidemiologic reduction points in disease incidence for an urban area in the northeast United States. Patients admitted to a pediatric hospital with worsening respiratory symptoms were tested using a multiplex PCR assay from nasopharyngeal swabs. The additive seasonal effects of outdoor temperatures and indoor relative humidity (RH) were evaluated. The 8-year average peak activity of human coronaviruses occurred in the first week of January, when droplet and contact transmission was enabled by the low indoor RH of 20-30%. Previous studies have shown that an increase in RH to 50% has been associated with markedly reduced viability and transmission of influenza virus and animal coronaviruses. As disease incidence was reduced by 50% in early March, to 75% in early April, to greater than 99% at the end of April, a relationship was observed from colder temperatures in January with a low indoor RH to a gradual increase in outdoor temperatures in April with an indoor RH of 45-50%. As a lipid-bound, enveloped virus with similar size characteristics to endemic human coronaviruses, SARS-CoV-2 should be subject to the same dynamics of reduced viability and transmission with increased humidity. In addition to the major role of social distancing, the transition from lower to higher indoor RH with increasing outdoor temperatures could have an additive effect on the decrease in SARS-CoV-2 cases in May. Over the 8-year period of this study, human coronavirus activity was either zero or >99% reduction in the months of June through September, and the implication would be that SARS-Cov-2 may follow a similar pattern.

A high school pool party "everybody thought was harmless" has fueled a second peak of coronavirus cases in Arkansas, Gov. Asa Hutchinson said Saturday.
"A high school swim party that I'm sure everybody thought was harmless," Hutchinson said at a press briefing, a video shows. "They're young, they're swimming, they're just having activity, and positive cases resulted from that."
