加拿大首席公共卫生官 11 月 10 日疫情通报 Remarks from the Chief Public Health Officer, November 10, 2022

大家好！在 COVID-19 疾病指标上，包括每周的病例数和实验室检测阳性率方面，近期在各个地区都存在着持续的地域差异。然而，SARS-CoV-2 病毒继续在全国范围内传播，包括新出现的奥密克戎变异毒株 BQ1.1 和 BF.7 呈现增长。与此同时，其他呼吸道病毒，包括呼吸道合胞病毒（respiratory syncytial virus，简称RSV）和流感已经增加到超过季节性水平，加拿大的呼吸道病毒季节提前开始了。在全国范围内，RSV 活动在几周前开始增加，实验室检测阳性率高于一年中这个时期的预期水平。近期以来，流感活动急剧增加，已经超过了实验室检测阳性率 5%的季节性门槛。这些监测指标表明需要加强预防措施，因为 SARS-CoV-2、流感和其他季节性呼吸道病毒可能在未来几周继续共同传播。我们可能都已知悉，有报告指全国许多地方的急诊科室都出现了严重的压力。这包括很多儿童医院，那里与 RSV 有关的入院人数非常多。此外，最近检测到的流感中，有一半以上是儿童和青少年。

在过去两年多的时间里，尽管公共卫生措施，包括我们的个人预防措施，遏制了 COVID-19 疾病和季节性呼吸道病毒的影响，但在 COVID-19 疫情的第三个冬天，我们也要注意一些问题。首先，随着人口公共卫生措施的放松，以及当面的课堂上课、面对面工作和社会活动，我们的接触率增加了。这意味着有更多机会接触到 COVID-19 以及其他季节性呼吸道病毒。此外，尽管加拿大人在接种 COVID-19 疫苗基础系列上实现了世界上最高的覆盖率，但许多人自上一次接种 COVID-19 疫苗或奥密克戎感染以来已经超过了 6 个月的时间间隔——因此免疫力正在下降，使我们所有人对严重疾病的保护程度有所降低。最后，但并非最不重要的是，对其他呼吸道病毒的免疫力也有所降低，因为过去两个冬天，这些病毒的流通量减少，而人们需要及时跟进流感疫苗的保护。

那么，对于这些令人关注的问题，我们需要做什么呢？我知道我们都很疲劳，但我们也知道，而且很清楚，可以帮助守护我们自己和其他人的健康的良好习惯有一长串，所以让我们专注其中三点最重要的建议：

1. 加强您的免疫保护力——如果距离您上次接种 COVID-19 疫苗或加强针已经有 6 个月时间，请接种二价针对奥密克戎毒株的加强针疫苗。此时也是接种流感疫苗的好时机。

• 保护您的呼吸道免遭病毒入侵——请勤洗手，在室内时佩戴质量好、贴合脸型的口罩，尤其是当您无法避免置身于拥挤或通风不良的空间之时。

• 减少对他人的传播——如果你出现症状，请待在家里！这有助于保护我们所有人，包括那些有症状的人。这有助于保护我们所有人，包括那些有高风险患上严重呼吸道疾病的高危人群，如免疫力低下的人，以及婴儿、幼儿、孕妇和老年人。保护那些处于最高风险、无法接种疫苗或没有做好强劲保护措施的人，这也是为了我们所有人而保护我们医疗体系承载容量的关键。

为了应对今年秋冬的挑战，让我们再次承诺，在恢复当面活动的同时，不要丧失我们已经取得的成果。尽管没有任何一层保护措施是完美的，但如果持续和共同使用不同层次的保护，“疫苗加多层保护”（Vaccines Plus layers）可以提供出色的防护，防止我们遭受 COVID-19 以及其他我们可能遇到的许多传染病。

Remarks from the Chief Public Health Officer, November 10, 2022

Bonjour à toutes et à tous. There is ongoing regional variation in COVID-19 disease indicators, including weekly case counts and laboratory test positivity. Nevertheless, SARS-CoV-2 virus transmission continues across the country, including with increased growth of emerging Omicron variants BQ1.1 and BF.7. At the same time, other respiratory viruses including respiratory syncytial virus – or RSV – and influenza have increased to above seasonal levels as respiratory virus season gets underway early in Canada. At the national level, RSV activity began to increase several weeks ago, with lab test positivity above expected levels for this time of the year. More recently, influenza activity increased steeply and has already crossed the seasonal threshold of 5% lab test positivity. These surveillance indicators point to

the need for stepped up precautions as SARS-CoV-2, influenza and other seasonal respiratory viruses could continue to co-circulate in the weeks ahead. We are likely all aware there are reports of heavy strain on emergency departments in many part of the country. This includes children’s hospitals, where RSV-related admissions have been very high. In addition, over half of recent influenza detections have been in children and teenagers.

Although public health measures, including our individual prevention practices, kept COVID-19 and seasonal respiratory viruses at bay over the past two plus years, this third winter of COVID-19 comes with some cautions. Firstly, with the relaxing of population public health measures and a return to in-person learning, work and social activities, our contact rates have increased. This means more opportunities for exposure to COVID-19 as well as other seasonal respiratory viruses. In addition, although Canadians achieved among the world’s highest coverage for a primary series of COVID-19 vaccines, many are beyond a six-month time lapse since the last COVID-19 vaccine dose or omicron infection– so immunity is falling, leaving us all less protected against severe disease. Last but not least, immunity to other respiratory viruses is lower given less circulation of these viruses over the past two winters as well as the need to update influenza vaccine protection.

So what do we need to do about these concerns? I know we are all tired and we know, only too well, the long list of good habits that can help keep us and others healthier, so let’s focus in on the top three recommendations:

4. Boost your immunity – if it has been 6 months since your last COVID-19

vaccine dose or booster, get vaccinated with a bivalent omicron-targeting booster. It is also a good time to get your flu shot.

5. Protect your respiratory tract from invading viruses – keep up with

handwashing and wear a good quality, well-fitting facemask when indoors,

especially if you can’t avoid being in crowded or poorly ventilated spaces.

6. Reduce spread to others – if you have symptoms please stay home! This helps protect us all, including those at high risk of severe respiratory illness such as those who are immunocompromised, as well as infants, young children, pregnant people and older adults. Protecting those who are at highest risk and can’t be vaccinated or don’t mount strong protection is also key to protecting health system capacity for us all.

To meet the challenges of this fall and winter, let’s recommit to not lose the gains we’ve made as we resume in-person activities. Although no individual layer of protection is perfect, when used consistently and together, Vaccines Plus layers can provide excellent protection against COVID-19 as well as many other infectious diseases we may encounter.

Thank you – Merci – Miigwetch
