A knowledge graph that integrates case numbers reported by John Hopkins University and population data from the UN. Work in progress, looking for more datasources, PR welcome!
The graph is available in a Neo4j Sandbox: https://10-0-1-172-33065.neo4jsandbox.com/browser/

You can add it to Neo4j Desktop with the bolt URL, same user/password: bolt://100.24.206.62:33064
Confirmed/death/recovered per country

WHERE c.name = 'China'
RETURN c.name, sum(u.confirmed)Confirmed cases for one country (percentage of the total population)
MATCH (c:Country)-[r:CURRENT_TOTAL]->(:AgeGroup)

MATCH (c)<-[:PART_OF]-(:Province)-[:REPORTED]->(u:DailyReport:Latest)

RETURN Country, Population, Confirmed, (toFloat(Confirmed)/Population)*100 AS percent ORDER BY percent DESCConfirmed cases (total and percentage) for all entries for a country (one row for each province, many rows for China) -> query works only for countries that have only one province
MATCH (c:Country)-[r:CURRENT_TOTAL]->(:AgeGroup)
WHERE c.name = 'Germany'
WITH c, sum(r.count) AS population
MATCH (c)<-[:PART_OF]-(p:Province)-[:REPORTED]->(u:DailyReport)
RETURN DISTINCT c.name, p.name, u.date, population, u.confirmed, (toFloat(u.confirmed)/population)*100 AS percent ORDER BY u.date DESC LIMIT 10Timeline of confirmed cases by country (aggregated over all provinces)
MATCH (c:Country)<-[:PART_OF]-(:Province)-[:REPORTED]->(u:DailyReport)
WHERE c.name = 'China'
WITH DISTINCT [u.date.year, u.date.month, u.date.day] AS date, sum(u.confirmed) AS sum
RETURN date, sum ORDER BY date- problem: not every province for China is reported every day, thus the sum of all confirmed cases on data e.g. 18.03. does not equal the total nunber of confirmed cases at that date (because province X did report last on 17.03.)
Number of people older than 70 in a country
match (c:Country)-[r:CURRENT_TOTAL]-(ag:AgeGroup)
WHERE c.name = 'Germany' AND ag.start >= 70
RETURN sum(r.count)John Hopkins University (JHU) aggregates data from WHO and other health organizations in a daily report. It contains the number of confirmed cases, deaths and recovered patients.
