An American working at the US Consulate in southern China reported experiencing “abnormal” sounds and pressure that resulted in a mild brain injury — reminiscent of a mysterious illness that recently hit diplomats in Cuba, officials said Wednesday.

The unnamed employee in the city of Guangzhou “recently reported subtle and vague, but abnormal, sensations of sound and pressure,” the State Department said in an emailed statement to US citizens in China.

“The US government is taking these reports seriously and has informed its official staff in China of this event,” the statement added about the symptoms, which occurred from late last year to April.

The worker, who was sent to the US for further evaluation, was diagnosed with a mild traumatic brain injury on May 8.

“The (State) Department is taking this incident very seriously and is working to determine the cause and impact of the incident,” US Embassy spokeswoman Jinnie Lee told Agence France-Presse.

“The Chinese government has assured us they are also investigating and taking appropriate measures,” she added.

The Chinese foreign ministry could not be immediately reached for comment.

“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 embassy’s health alert said. “Instead, move to a location where the sounds are not present.”

US diplomatic officials said they could not link the case to health issues suffered by US government staff in Cuba dating back to late 2016.

“We cannot at this time connect it with what happened in Havana, but we are investigating all possibilities,” a US Embassy official told Reuters.

The US has disclosed that 24 diplomats and their relatives had fallen victim to an unsolved mysterious attack in Cuba that left them with injuries resembling brain trauma.

The victims had associated the onset of their symptoms with “unusual sounds or auditory sensations,” a State Department physician told the US Senate in January.

They suffered headaches, hearing loss, disorientation and some loss of cognitive ability.

Officials initially suspected the Americans had been targeted by an acoustic weapon, but media reports have suggested that the FBI has been unable to verify any evidence to support that theory.

The US government has held Cuba responsible, arguing that Raul Castro’s authoritarian state must have either carried out the assaults or at least known who was responsible.
