都柏林2020年12月23日 – 爱尔兰卫生官员认为，在邻国英国发现的一种新冠病毒新变种在爱尔兰存在，但这并不是疫情在该国迅速传播的唯一原因。疫情迅速传播将使爱尔兰需要采取比24小时前宣布的更为严厉的限制措施。
在英国控制的北爱尔兰周三也发现了新冠病毒新变种。
国家公共卫生应急小组(NPHET)还向政府提出了新的未指明的建议，而就在一天前，部长们刚大幅收紧对新冠疫情的限制。
爱尔兰首席医疗官Tony Holohan在记者会上未就新建议置评。爱尔兰将从周四开始关闭餐馆、酒吧和一些零售店，这是该国第三次关闭，部长们说这可能会持续到3月初。
NPHET要求从12月26日起关闭所有零售商。与近期限制措施不同的是，健身房和百货店等商店目前可以继续营业。在明年1月1日之前，也允许一些家庭互访。
一位政府发言人称，在内阁就NPHET的建议进行讨论前不就此置评。

一、患者基本情况付某某，男，北京市顺义区常住居民，因要参加研究生考试，按照北京市防控要求，于12月22日9:30在北京进行核酸检测。12月23日2:30，北京市顺义区疾控中心接到第三方检测公司阳性检测报告，12月23日8:30，经北京市疾控中心复核，确认为新冠病毒核酸阳性。
12月22日16时许，该病例及同行同事3人（赵某某、王某、谷某某）在北京首都机场同乘CA8347航班（北京首都机场-宁波栎社国际机场，17:45起飞，20：15抵达）到宁波出差。出宁波机场后，乘坐滴滴车前往奉化，在奉化斗门牛肉干面店就餐后，入住奉化区华侨豪生酒店。
二、目前采取的措施接北京相关部门对该病例检测确认信息后，市委市政府和奉化区委区政府高度重视，第一时间启动应急响应，及时由120负压救护车将该病例从隔离酒店转运至定点医疗机构进行诊治，目前无发热、咳嗽、乏力等自觉症状。
截至12月23日17:00，现已排查到同行人员、同航班人员、出租车司机、酒店和餐馆服务人员等共260名密切接触人员（包括次密切接触者），其中外市人员10人，目前已落实集中隔离管控、核酸检测、追踪协查等各项防控措施。已对该病例、同行3人及酒店等外环境采集标本进行了检测，结果显示，该病例咽拭子新冠病毒核酸阳性，血清抗体阴性；同行3人咽拭子及外环境样本核酸检测均为阴性。同时，已对奉化区华侨豪生酒店、斗门牛肉干面店等场所进行了全面消杀。
On December 18, 2020, the U.S. Food and Drug Administration issued an emergency use authorization (EUA) for the second vaccine for the prevention of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The emergency use authorization allows the Moderna COVID-19 Vaccine to be distributed in the U.S for use in individuals 18 years of age and older.
Emergency Use Authorization Status:AuthorizedName:Moderna COVID-19 VaccineManufacturer:ModernaTX, Inc.
For the prevention of 2019 coronavirus disease (COVID-19) for individuals 18 years of age and older
The most commonly reported side effects, which typically lasted several days, were pain at the injection site, tiredness, headache, muscle pain, chills, joint pain, swollen lymph nodes in the same arm as the injection, nausea and vomiting, and fever. Of note, more people experienced these side effects after the second dose than after the first dose, so it is important for vaccination providers and recipients to expect that there may be some side effects after either dose, but even more so after the second dose.

现在这是一个激烈争论的问题。一种可能性是，该变种在一组特殊宿主体内获得了一系列新突变。
在典型的感染案例中，人们染上新冠病毒，感染几天后才会出现症状。当免疫系统进行防御时，病毒在体内的数量就会减少。除非患者出现了严重的新冠症状，不然他们通常最多在几周内就能将病毒完全清除。
但有时免疫系统较弱的人会被病毒感染。在他们体内，病毒可以活跃数月之久。对这些免疫缺陷患者的病例研究表明，病毒长期在他们体内复制时，会积累大量突变。
研究人员发现，随着时间推移，自然选择有利于能够躲避免疫系统的变异病毒。研究人员还提出，病毒变异的进化可能是患者服用的药物所推动的。一些变种可能具备对单株抗体等药物的耐受能力。
其他科学家提出，在病毒重新感染人群之前，可能通过在动物群体（如水貂）中传播而获得新的突变。随着越来越多的动物感染被发现，这样的“动物宿主”已经成为引发人们强烈关注的焦点。
The COVID-19 emergency hospital at the Wisma Atlet Kemayoran in Central Jakarta has started a study on early COVID-19 detection through a conjunctival swab test, after patients reported experiencing eyesight issues prior to showing the disease’s usual symptoms.
“This could be a cheap and quick screening method to detect COVID-19 in patients in order to advance treatment,” Tugas Ratmono, the coordinator of the COVID-19 emergency hospital, said as quoted by tempo.co on Monday.
This research was based on a hypothesis that SARS-CoV-2, the virus that causes COVID-19, can also spread to the patients’ eyes because the eyes and nasal cavity are connected by a canal.
“People are prohibited from rubbing their eyes with their hands because the eyes could be an entrance for the coronavirus to enter human’s bodies,” Tugas said.
The research is being conducted by the hospital’s main researcher Rina La Distia Nora with her coworkers Rina Dwi Ningtias Mei Riasanti and Gladya Utami. The study is titled “Early SARS-CoV-2 Detection of Conjunctiva Swab Sample Through PT-PCR Examination”.
The study itself was conducted in hopes that swab tests could be done with a conjunctival swab. The sample will later be examined through the reverse transcription-polymerase chain reaction (RT-PCR), which is similar to the extraction of samples from the nasal cavity and throat.
Wisma Kemayoran, Tugas continued, was supporting the study so that it could be applied to detect COVID-19.
“This research is very important, not only to explore other possibilities to treat COVID-19 but also strategies to overcome other health threats,” Tugas said.
A study published in the monthly peer-reviewed medical publication Journal of Medical Virology in June also examined the possibilities of detecting SARS-CoV-2 RN in conjunctival secretions.
The research, “Detecting SARS-CoV-2 RNA in Conjunctival Secretions: Is It a Valuable Diagnostic Method of COVID-19?” aimed at evaluating the presence of the virus’s RN in conjunctival swab specimens.
The study, which was conducted at the Hospital Clinico San Carlos of Madrid in Spain, was participated by 36 subjects from the COVID-19 admission unit who tested positive for the virus. It highlights how the SARS-CoV-RNA could be detected in conjunctival secretions of both patients with and without conjunctivitis.
However, the research also found that PCR essay of tears and conjunctival secretions appear to have a fairly low potential to detect the virus.
The Kemayoran hospital administration head, RM Tjahja Nurrobi, said the hospital served as a research center to support the study because of the large number of COVID-19 patients treated there.
Tjahja said the hospital had conducted 70 studies to treat COVID-19 patients so far.
