COVID19-figures on aviation are rare.
A thread about (the search for) this data.
We've collected 4.400 flights with at least one contagious(!) person.

✈️Flying during COVID19 - the numbers
COVID19 & variants spread worldwide, also by aviation.
Despite precautions like PCR- and Antigen-tests.
Why are there no figures?
● Commercial interests?
● Inconvenient? (we want to travel)
● Too difficult?
No... it's not too difficult.

How many affected persons per flight?
Hard to tell for the Canada-data. It mentions 3 "rows" around the person.
E.g. an affected person (or group, like a family) is on row 5, the site reports: "Rows 2 to 8".
Often you see several blocks:

Currently #travelbans are discussed.
Is a ban effective?
It depends, some bans can be avoided with a stopover.
With all the extra risks that come along like extra traveltime, tests, hotel, airport.
E.g. India to The Netherlands via stopover
De gemeente waar de 1e uitbraak van de 🇬🇧Britse B.1.1.7 variant werd gevonden, waarop @GGD_RR en @ErasmusMC en @Lansingerland de ca. 63.000 inwoners opriepen voor een test.
Gisteren zijn nieuwe cijfers op het dashboard van @GGD_RR geplaatst
Het RIVM meldde afgelopen dinsdag al op rivm.nl/nieuws/opmars-… dat het testen in Lansingerland het landelijk percentage positief met 0,7% omlaag bracht en in de GGD regio Rotterdam Rijnmond zelfs met 5,9%:
We zien een flinke toename van het aantal afgenomen testen in Lansingerland.
Er is geen grote stijging in het aantal positief getesten per week. Hierdoor is het percentage positief getest flink omlaag gegaan.
Een snelle toename van besmettingen is dus nog niet geconstateerd.
