U.S. warns citizens in China after 'abnormal' sound injures consulate worker

[May 23, 2018]    BEIJING (Reuters) - An American citizen working at the U.S. consulate in the southern Chinese city of Guangzhou has reported suffering from "abnormal" sounds and pressure leading to a mild brain injury, the U.S. embassy said on Wednesday.

The embassy, which issued a health alert to Americans living in China, said it could not link the case to health issues suffered by U.S. government staff in Cuba dating back to late 2016.

The unnamed American citizen assigned to the consulate in Guangzhou had reported a variety of "physical symptoms" dating from late 2017 to April this year, the U.S. embassy in Beijing said in an email.

The worker was sent to the United States for further evaluation. "The clinical findings of this evaluation matched mild traumatic brain injury (MTBI)," the embassy said.

The State Department was taking the incident very seriously and working to determine the cause and impact, the embassy said.

It added the Chinese government told the embassy it is also investigating and taking appropriate measures.

"We cannot at this time connect it with what happened in Havana, but we are investigating all possibilities," a U.S. embassy official told Reuters.

China's Foreign Ministry did not immediately respond to a request for comment.

The U.S. government on Wednesday issued a health alert to Americans in China, warning them about the incident it described as "subtle and vague, but abnormal, sensations of sound and pressure".

"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. Instead, move to a location where the sounds are not present," the emailed alert said.

The U.S. government in October expelled 15 Cuban diplomats from the United States for what it said was Cuba's failure to protect staff at the U.S. embassy in Havana from mysterious health incidents at one point thought to possibly have been acoustic "attacks".

Staff there reported symptoms including hearing loss, dizziness, fatigue and cognitive issues, though Cuban officials dismissed the idea of acoustic strikes as "science fiction" and accused Washington of slander.

The cause of those incidents remains unresolved.

The Canadian government in April said it would remove families of diplomats posted to Cuba after Canadian personnel there in 2017 also reported similar health symptoms.
