bevestiging dat het DE TEMPERATUUR is kan ik niet vinden, er zijn geen fatsoenlijk_onafhankelijke co-correlaties onderzocht. Verder zeer interssant onderzoek.
De onderzoekers van de twee rapporten realiseren zich dit gelukkig ook, hun tekst even opgeknipt en 'n aantal kernwoorden/zinnen uitgelicht.

However, there is more to seasonality than the simple effect of temperature variations.
Furthermore, other critically important factors are involved,
such as lockdown implementation,
public education about hand hygiene and social distancing,
quarantine for travellers and
self-isolation.
Some believe that with the arrival of spring and summer, the transmission of the virus will be reduced in the Northern Hemisphere, while it will rise in the Southern Hemisphere where low- and middle-income countries could face devastating strains on their healthcare systems [30].

This study shows that there is a robust and significant negative association between COVID-19 transmissibility and ambient temperature at the country level.
Our result is highly significant at the 1% level (p-value=0.005 in the multivariable analysis), which compares with a significance level of 5% (p-value=0.049 when temperature is over 7°C) in Ran et al. [2].
While this is in line with the results of Ran et al. [2] and we improved upon this study
by adding important covariates (McFadden's pseudo-R-squared in their study is 11% as compared to 72% in our study),
both studies cannot isolate
the effect of UV radiation that is correlated with heat and seems to kill the virus quite quickly in experiments,
the fact that people spend more time outside
if the temperature is warmer, or the enhanced vitamin D production of the human body in sunnier conditions [3].
We suggest that the causal impact of temperature on COVID-19 transmissibility and
the underlying mechanisms such as
virus viability, the
host immunity, and
people's behaviour
should be further explored in more in-depth studies.
