US tuberculosis 事例／患者s were at the highest level in a １０年間 in 2023
NEW YORK (AP) - The number of U.S. tuberculosis 事例／患者s in 2023 were the highest in a １０年間, によれば a new 政府 報告（する）／憶測.
Forty 明言する／公表するs 報告（する）／憶測d an 増加する in TB, and 率s were up の中で all age groups, the 中心s for 病気 支配（する）／統制する and 予防 said Thursday. More than 9,600 事例／患者s were 報告（する）／憶測d, a 16% 増加する from 2022 and the highest since 2013.
事例／患者s 拒絶する／低下するd はっきりと at the beginning of the COVID-19 pandemic, but have been rising since.
Most U.S. TB 事例／患者s are 診断するd in people born in other countries. 専門家s say the 2023 number is in part a combination of a 殺到する in TB 事例／患者s 国祭的な - the World Health Organization said TB was behind only COVID-19 in 感染性の 致命的な 病気s 世界的な in 2022. And there are also 増加するs in 移住 and 地位，任命する-pandemic international travel.
But other factors are also at play, 含むing other illnesses that 弱める the 免疫の system and 許す latent TB 感染s to 現れる.
CDC 公式の／役人s 推定する／予想するd TB numbers would rise, but the 2023 count "was a little more than was 推定する／予想するd," said Dr. Philip LoBue, director of the 機関's 分割 of Tuberculosis 排除／予選.

にもかかわらず the jump, the number and 率 of new TB 事例／患者s each year remains smaller than it was in the past, and the U.S. has a lower 率 of new TB 事例／患者s than most countries.
Tuberculosis is 原因（となる）d by bacteria that usually attack the 肺s, and is spread through the 空気／公表する when an 感染性の person coughs or sneezes. If not 扱う／治療するd 適切に, it can be 致命的な. In the late 1800s, TB killed one out of every seven people living in the 部隊d 明言する／公表するs and Europe. But the 開発 of 抗生物質s and public health 成果／努力s 後継するd in 扱う／治療するing 感染s and 跡をつけるing 負かす／撃墜する those they 感染させるd, 主要な to 事例／患者s 落ちるing for １０年間s.
The new CDC 統計（学） are not a count of how many people were newly 感染させるd in 2023, but rather of how many people developed a cough or other symptoms and were 診断するd.
An 概算の 85% of the people counted in 2023 were 感染させるd at least a year or two earlier and had what´s called latent TB, when the bacteria enters the 団体／死体 and hibernates in the 肺s or other parts of the 団体／死体. 専門家s 見積（る） as many as 13 million Americans have latent TB and are not contagious.
When the 免疫の system is 弱めるd - by 確かな 医薬s or other illnesses like 糖尿病 and HIV - the TB wakes up, so to speak. Nicole Skaggs said she was 感染させるd in 2020, but didn´t develop symptoms until 2022 - after she got sick from COVID-19.
"Anything that can take out or lower your 免疫の system can put you at 危険," said Skaggs, 41, a 所有物／資産／財産 経営者／支配人 in Bothell, Washington.
CDC 公式の／役人s called the idea that COVID-19 has played a 役割 in 増加するd reactivation of TB "an important question." Scientists are still learning what 原因（となる）s latent TB to 反動的な and "I would consider it an unknown at this point," LoBue said.
"It´s too 早期に to tell" what will happen to TB 傾向s in the next few years, he also said.
There are TB ワクチンs 存在 developed, and public health 労働者s that were 焦点（を合わせる）d on COVID are now 支援する to trying new approaches to 妨げるing TB. New York City, which saw 事例／患者s jump 28% last year, is 雇うing TB 事例／患者 経営者／支配人s and community health 労働者s and ますます using ビデオ 監視するing of 患者s taking 医薬s to keep 治療 率s high, said Dr. Ashwin Vasan, the city´s health commissioner.
On the other 手渡す, 連邦の TB 基金ing for 明言する／公表する and 地元の health department 成果／努力s has been flat, and one of the 重要な 抗生物質s used against TB has been in short 供給（する） in 最近の years. 加える, 麻薬-抵抗力のある TB 感染s have popped up in a fraction of 事例／患者s.
