Number of attacks on health care in Ukraine monthly 2022-2023

As of September 13, 2023.
The figures are obtained from the surveillance system for attacks on health care (‎SSA) by the World Health Organization. SSA is "a global and standardized monitoring system for the collection of primary data about attacks on health care."
The source specified the following information: "WHO defines an attack on health care as any act of verbal or physical violence or obstruction or threat of violence that interferes with the availability, access and delivery of curative and/or preventive health services during emergencies. The nature and types of attacks vary across contexts and can range from violence with heavy weapons to psychological threats or intimidation.
Each reported attack is assigned a level of certainty by a designated WHO staff member which conveys a level of confidence that the reported attack has occurred. The level of certainty applies to whether the attack occurred, but does NOT apply to the detailed data about the attack. To maintain accuracy of WHO-reported data, the SSA verification method assigns increasing levels of certainty based on the amount of data that is available and the supporting evidence. There are four levels of confidence: “rumour”, “possible”, “probable”, and “confirmed”. Any report assigned the level “rumour” is not published on the SSA dashboard. The criteria for determining the level of certainty of an attack is based on the sources of information available to triangulate the data."

The methodology of the study can be found on the source's web page.
