COPD and pneumonia
Chronic obstructive pulmonary disease (COPD) is a collection of lung diseases that cause blocked airways and make breathing difficult. It can result in serious complications.
People with COPD are more likely to develop pneumonia. Pneumonia is particularly dangerous for people with COPD because it causes an increased risk of respiratory failure. This is when your body is either not getting enough oxygen or isn’t successfully removing carbon dioxide.
Some people aren’t sure if their symptoms are from pneumonia or from worsening COPD. This can cause them to wait to seek treatment, which is dangerous.
If you have COPD and think you might be showing signs of pneumonia, call your doctor right away

Important info as two friends have died from pneumonia out here. I'm sure you must know someone if you've been out here a few years too.
I read a study that suggested that high or low humidity were good living environments for Corona viruses, but at around 50% rh +or- 10% or so, it became inactive on surfaces a lot sooner.
Effects of Air Temperature and Relative Humidity on Coronavirus Survival on Surfaces
Assessment of the risks posed by severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) on
surfaces requires data on survival of this virus on environmental surfaces and on how survival is affected by
environmental variables, such as air temperature (AT) and relative humidity (RH). The use of surrogate viruses has the potential to overcome the challenges of working with SARS-CoV and to increase the available data on coronavirus survival on surfaces. Two potential surrogates were evaluated in this study; transmissible
gastroenteritis virus (TGEV) and mouse hepatitis virus (MHV) were used to determine effects of AT and RH
on the survival of coronaviruses on stainless steel. At 4°C, infectious virus persisted for as long as 28 days, and
the lowest level of inactivation occurred at 20% RH. Inactivation was more rapid at 20°C than at 4°C at all
humidity levels; the viruses persisted for 5 to 28 days, and the slowest inactivation occurred at low RH. Both
viruses were inactivated more rapidly at 40°C than at 20°C. The relationship between inactivation and RH was
not monotonic, and there was greater survival or a greater protective effect at low RH (20%) and high RH (80%)
than at moderate RH (50%). There was also evidence of an interaction between AT and RH. The results show
that when high numbers of viruses are deposited, TGEV and MHV may survive for days on surfaces at ATs and
RHs typical of indoor environments. TGEV and MHV could serve as conservative surrogates for modeling
exposure, the risk of transmission, and control measures for pathogenic enveloped viruses, such as SARS-CoV.

Up the workers!
In a report yesterday, Cambodia was used as an example of a country that will not fare well if there is an outbreak there. The concerns are the health system is inadequate to cope.
The RO will differ from country to country, depending on their health system infrastructure., The projected mortality in some of those countries could be as high as 14%.

It's much too hot here. The health minister said so, and he should know.

The health infrastructure won't have an impact on the R0, but the governments ability to contain it could. But Cambodia has some big advantages, the first is the climate, the second is the size of the rural population and it's level of self sufficiency. Most Cambodian's wouldn't find it too hard to self-quarantine if required.kinard wrote: ↑Thu Feb 13, 2020 2:42 amIn a report yesterday, Cambodia was used as an example of a country that will not fare well if there is an outbreak there.

But agreed on the health system, the mortality rate could be much higher for anyone that reached the pneumonia stage due to the total lack of ICU beds nation wide.
I think we are much less likely to contract it here, but if someone did and they were in an at risk group, the outlook would be very grim.
The current Metar at VDPP (Phnom Penh airport) is:
VDPP 130500Z 13007KT 9999 SCT017 31/21 Q1012
So, temperature 31 degrees, dewpoint 21 degrees, which translates to roughly 55% relative humidity.

But the rh goes way up at night to around the 90's. I guess it may get transmitted more in the wet season?v12 wrote: ↑Thu Feb 13, 2020 12:15 pmThe current Metar at VDPP (Phnom Penh airport) is:

Yes, so at night (also because of lower temperature), the virus has a higher chance to survive, though during the day it gets "killed". And what is already killed (and not even enters the night) will not survive the period of higher RH. The next daytime gives again another massacre for the remaining virus (which does not "grow" during periods with higher RH, it just doesn't die)kungfufighter wrote: ↑Thu Feb 13, 2020 12:30 pmBut the rh goes way up at night to around the 90's.

And yes, in just a few months, things may get more threatening for Cambodia.
Though, on the other hand, the winter weather in China, and more the Northern Hemisphere, will be over, flue season over, so the "natural" spread of flue will become much lower and it can be expected also CoViD-19 will diminish (though no guarantee it will disappear completely).
Hmmm.
Well the first thing that will happen here is all the hospital staff will fuck off quick-smart, like iced up bus drivers.

When SARS was at its peak, they predicted 100,000 people could die.
Guess how many actually died?
20-30

Your estimates are a bit off apparently it was 777 or so?spitthedog wrote: ↑Mon Mar 02, 2020 8:13 pmWhen SARS was at its peak, they predicted 100,000 people could die.
