印度新冠變異能逃過核酸檢測？

剛剛在微信上和網上看到許多報道，說的是同一件事。

最初的報道是中國CDC的英文 Newsletter，但可能是為了聳人聽聞，中文媒體故意刪掉了重要的一句話，最開始是暗指這種變異不容易被測出，而後來的轉抄者就直接加上了“逃脫檢測”等說法。

我希望媒體報道要有底線，不能亂講。

英文報道原文：

Three Chinese males on a flight that arrived in Chongqing from India via Nepal were confirmed infected with a coronavirus variant that is spreading in India, according to the Chinese Center for Disease Control and Prevention.

The center said on Saturday in China CDC Weekly that the men, aged from 20 to 30, were infected with B.1.617, an emerging variant in India that was first identified in October.

The men, who were probably infected there, the China CDC said, were coworkers at a cellphone company based in Noida, India, since late 2019.

An epidemiological investigation returned negative COVID-19 tests on multiple occasions in India before their return trip, which began on April 19. Preventive measures were taken throughout the trip — wearing protective clothing, N95 masks, goggles and gloves. The men went from Noida to New Delhi by car, then flew to Kathmandu, Nepal, and stayed at a hotel there for two days. They flew to Chongqing on April 21.

But new coronavirus tests at Chongqing Customs were positive, and the men were transferred to the Chongqing Public Health Medical Center, the designated COVID-19 hospital.

Test specimens taken from the men were sent to Chongqing CDC and sequenced on April 28 and 30 and later found to be related to the Pangolin lineage B.1.617, the emerging strain. It was recently designated as a variant of interest by the World Health Organization.

網上的中文（來自新加坡《聯合早報》）：

論文顯示，三名年齡在20-30歲之間的患者來自同一家手機公司，該公司在印度諾伊達（Noida）設有生產基地，自2019年底以來他們一直與印度同事在那裏工作

流行病學調查報告顯示，三人於4月19日包車從印度諾伊達到新德裏，當天轉機飛往尼泊爾加德滿都。他們在整個行程中都穿著防護服，N95口罩，護目鏡和手套。

他們在加德滿都乘坐包車到達旅館，在那裏住到4月21日，21日早乘坐包車去機場，並采取了充分保護措施，然後飛往中國重慶市。

報告顯示，他們在印度的核酸檢測多次出現陰性，而患者A和患者B的最新陰性結果是4月17日，患者C的最新陰性結果是4月19日。

三人在重慶被轉移到冠病救治定點醫院重慶公共衛生醫療中心，體溫均正常，但胸部CT結果提示感染性病變，被確診為冠病病例。

論文顯示，確診患者的樣本已送至重慶市疾病預防控製中心，於4月28日至30日進行了測序。

基因組序列的分析表明，這些分離物屬於Pangolin譜係B.1.617，是印度的一種新興變種，在三個分離株中觀察變異位點與印度B.1.617.2變異體相同，支持這三例患者感染可能發生在印度。

最後到微信，變成了這個樣子：（繁體字，可能來自港台）

今日有三個在印度工作的中國人，由印度經尼泊爾返回國內，抵達重慶市時，初部檢測都是陰性, 但醫生仍有懷疑，於是幫他們進行CT電腦掃描，發現他們的肺部有病變，並確診是印度的三重變種病毒, 証明這種印度超級變種病毒，可以避過現在的檢測, 而大部份的關口都隻是靠一般普通測試,
