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.

However, later on Wednesday, U.S. Secretary of State Mike Pompeo told lawmakers that the “sonic attack” in China was “medically similar” to the incidents in Cuba.

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. Pompeo said that medical teams were heading to Guangzhou to investigate the incident.

The State Department 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.

Zika virus findings show hearing loss to some babies

CHICAGO (Reuters) – A study in Brazil of 70 babies whose mothers had confirmed Zika infections found that nearly 6 percent had hearing loss, adding a new complication to the list of ills the virus can cause when women are infected during pregnancy.

The Brazilian study, published on Tuesday in the U.S. Centers for Disease Control and Prevention’s weekly report on death and disease, confirmed less rigorous reports of deafness among infants born to mothers with Zika infections.

The finding is part of an effort to fully characterize the harm caused by the Zika virus during pregnancy. The virus is best known for causing the severe birth defect microcephaly, characterized by undersized heads and underdeveloped brains. But other studies have shown that Zika can cause other brain abnormalities, vision problems and joint deformities.

In the latest study, a team led by Dr. Marli TenĂ³rio and Dr. Ernesto Marques of the Oswaldo Cruz Foundation in Pernambuco, Brazil, examined records from 70 infants with microcephaly whose mothers had laboratory-confirmed Zika infections during pregnancy.

They found that nearly 6 percent had hearing loss without any other plausible cause.

Several other viral infections during pregnancy can cause hearing loss, including rubella and cytomegalovirus, or CMV, infections. The current study adds Zika infection to that list.

Scientists say Zika should now be considered a risk factor for hearing loss, and children who were exposed during pregnancy but have normal hearing at birth should be screened regularly for delayed or progressive hearing loss.

The connection between Zika and microcephaly first came to light last fall in Brazil, which has since confirmed more than 1,800 cases of microcephaly.
