How are cases reported?
We have three levels of case definition: suspected, probable and confirmed cases. What is measured and reported by governments and international organizations?
International organizations – namely the WHO and European CDC – report case figures submitted by national governments. Wherever possible they aim to report confirmed cases, for two key reasons:
1. They have a higher degree of certainty because they have laboratory confirmation;
2. They held to provide standardised comparisons between countries.
However, international bodies can only provide figures as submitted by national governments and reporting institutions. Countries can define slightly different criteria for how cases are defined and reported.4 Some countries have, over the course of the outbreak, changed their reporting methodologies to also include probable cases.
One example of this is the United States. Until 14th April the US CDC provided daily reports on the number of confirmed cases. However, as of 14th April, it now provides a single figure of cases: the sum of confirmed and probable.
Suspected case figures are usually not reported. The European CDC notes that suspected cases should not be reported at the European level (although countries may record this information for national records) but are used to understand who should be tested for the disease.

Even your heroes at the NYT provide the disclaimer now....................
In data for the United States, The Times is now including cases and deaths that have been identified by public health officials as probable coronavirus patients. Some states and counties only report figures in which a coronavirus infection was confirmed through testing. Because confirmed cases are widely considered to be an undercount of the true toll, some state and local governments have started identifying probable cases and deaths using criteria that were developed by states and the federal government.
Confirmed cases and deaths are counts of individuals whose coronavirus infections were confirmed by a laboratory test. Probable cases and deaths count individuals who did not have a confirmed test but were evaluated using criteria developed by national and local governments. Some governments are reporting only confirmed cases, while others are reporting both confirmed and probable numbers. And there is also another set of governments that are reporting the two types of numbers combined without providing a way to separate the confirmed from the probable. The Times is now using the total of confirmed and probable counts when they are available individually or combined. Otherwise only the confirmed count will be shown.

So, if you don't like the ECDC who have stated the guidelines or
the left-wing NYT for confirming that those data methodology guidelines are correct......just what data are do you follow? Twitter & FB????
