Looks like communication is a problem area for health care agencies. So I have made a list of talking points for them.
1. Omicron is a serious threat because it is highly transmissible, more than any previous variant, and too many people will get it too fast.
2. Omicron appears "mild" mainly because a lot of people have some prior immunity from prior Covid or vaccines or both. But it is quite capable of severe disease. Don't be complacent.
3. There are some who are particularly vulnerable to omicron:
a) Unvaccinated and inadequtely vaccinated. Unvaccinated includes those for whom vaccines not available to them (eg., young children; people in low income countries)
b) those with compromised immune system
4. Omicron doesn't affect only those it infects. It affects us all. Because rapid rise in cases overwhelms hospitals and affects care for other illnesses. Doctors and nurses get infection and have to isolate creating major staff shortages.
5. What you can do is to get vaccinated and boosted because data show vaccines protect against hospitalizations, ICU admissions, and deaths.
6. What you can do is to continue other important preventive measure like mask, ventilation, avoiding crowded gatherings etc.
The next month is going to be very difficult everyone.
We are lucky that vaccines were developed in time. They have helped reduce severity.
We are unlucky in that 40% of the country is not yet fully vaccinated. And 80% have not yet received the booster dose.
Cases occurring so incredibly fast in such a short time leads to 2 problems. 1) even if proportion who need hospitals is small, it is big in absolute terms: overwhelms hospitals. 2) staff shortages due to illness or quarantine causes problems for care for all other illnesses.
Omicron hopefully once. The virus mutated enough to spread more rapidly and evade vaccines and prior infection immunity, but lost some virulence in the process.
It can still cause harm and disrupt life, but this is a bit of much needed hope
A milder variant can still cause problems. It may also appear milder than it is because a lot of people have pre existing immunity from prior Covid and vaccinations. So we cannot be complacent that it is milder.
Hope for the New Year comes from South Africa: the omicron wave peaks quickly in 3 weeks. And comes down quickly.
Much faster than previous waves.
Hope for the New Year also comes from the UK where despite the wave peaking more than two fold higher than previous waves, deaths remain lower due to many factors including existing immunity from vaccines and prior COVID.
Not the difference between cases and deaths this time.
Omicron doesn't seem to mind prior infection or vaccination in terms of ability to cause infection— but based on how it's playing out in South Africa and UK, severity will be lower because prior infection and vaccine induced immunity will continue to protect from severe disease.
