A new professional ethics: Karl Popper and Xenophanes’ epistemology

It is not a secret that I admire the work of Karl Popper, both as a philosopher but also as a very precise historian that tried to dismiss many misunderstandings of the past.

I was reading the book The World of Parmenides, which is a collection of Popper’s essays on the Presocratic Enlightenment, and found a very interesting insight on how the epistemology of Xenophanes led naturally to a professional ethics. This link isn’t widespread nowadays, but it certainly deserves more divulgation as it is a natural consequence of the conjectural knowledge we possess.

First early R0 estimate for Portugal COVID-19 outbreak

Just posting the first early estimate for the COVID-19 R_0 (basic reproduction number) in Portugal outbreak. Details on the image, more information to come soon. This estimate is taking into consideration the uncertainty for the generation interval and the growth.

COVID-19 Analysis: Symptom onset to confirmation delay estimation for states in Brazil

Since the generation time of a virus is very difficult to estimate, most studies rely on the serial interval which is estimated from the interval between clinical onsets. Given that most analysis use the serial interval, it is paramount to have an estimate of the precise onset dates of the symptoms.

I did a analysis for all states in Brazil using data from SIVEP-Gripe, the complete analysis is available here.

In the image above, we can see the gamma mean estimate for the delay on each state in Brazil. Below you can see the distribution for Rio Grande do Sul / RS:
