US Staffer in China Suffers From Brain Injury After Mysterious ‘Sound’ Incident

May 23, 2018 Updated: May 23, 2018

A US government employee in China reported experiencing a mysterious and “abnormal” sound that caused him to suffer from a mild traumatic brain injury (MTBI).

A Wednesday, May 23, health warning emailed to American citizens from the consulate in Guangzhou, noted that the sensations the employee felt were “subtle and vague.”

In the alert, U.S. Officials said that they currently do not know what caused the reported symptoms, adding that the government is taking the incident “seriously” and has informed Chinese officials of the event.

According to the alert, there have been no other similar incidents in China, inside or outside the government.

“While in China, if you experience any unusual acute auditory or sensory phenomena accompanied by unusual sounds or piercing noises, do not attempt to locate their source,” the alert said. “Instead, move to a location where the sounds are not present.”

The unnamed employee, assigned to the Guangzhou consulate, reported the symptoms from late 2017 through April this year. A US embassy official told Reuters that the employee suffered from a variety of “physical symptoms” during that period of time.

“If you have concerns about any symptoms or medical problems that developed during or after a stay in China, consult a medical professional,” the warning stated.

The staffer was sent to the United States for further evaluation, where clinical findings found that the symptoms matched those of an MTBI.

Cuban Connection 

US officials did not explicitly link the incident to other cases, but it appears similar to another unexplained “sonic or sound” attack in Cuba last year, that left some 21 embassy staffers ill.

The employees, working for the US embassy in Havana, appeared to have been targeted. Their symptoms included hearing loss, dizziness, fatigue, and cognitive issues, according to Reuters.

Cuban officials at the time denied knowing that the incident was from a sonic attack.

In response to the incident, the US government has issued a level 3 travel advisory to Cuba.

“Because our personnel’s safety is at risk, and we are unable to identify the source, we believe U.S. citizens may also be at risk,” the March 2, 2018, advisory states. “The U.S. Embassy in Havana is operating with reduced staffing and, as result, has limited ability to assist U.S. citizens, particularly outside Havana.”

The incident in China comes as Secretary of State Mike Pompeo meets with Chinese Foreign Minister Wang Yi in Washington to discuss trade on Wednesday afternoon.
