Prevention and treatment services for noncommunicable diseases (NCDs) have been severely disrupted since the COVID-19 pandemic began, according to a WHO survey released from Geneva on Monday.    The survey, which was completed by 155 countries during a three-week period in May, confirmed that the impact is global, but that low-income countries are the most affected.   This situation is of significant concern because people living with NCDs are at higher risk of severe COVID-19-related illness and death.   Noncommunicable diseases kill 41 million people each year, equivalent to 71% of all deaths globally, according to WHO.
