[Thread] 1. What's happening with #COVID19 hospital admissions in SA?

Waasila Jassat, @nicd_sa:
- Over the past 14 days, admissions have decreased between 18% and 59% in all provinces
2. Your risk of hospitalisation due to an #Omicron infection is about 50% lower than in Wave 1,2,3 in SA (the risk for each wave = slightly different)

Most admissions in Wave 4 (#Omicron) = people between 20 and 39 years. In Wave 1,2,3 = admissions of people between 40 and 70.
3. Even though there were more admissions among younger people during our #Omicron wave, people's risk of admission still increased with age. So the older you were, the more likely you were to get very sick with #COVID.
4. Jassat:

Once you're admitted to hospital for #COVID19 in SA, your risk of dying of it is much higher if you were admitted to a public sector hospital than a private sector hospital.
5. Jassat:

In SA, the most common comorbidity associated with a #COVID19 patient who gets hospitalised, is hypertension (high blood pressure). The second most common comorbidity is diabetes and patients almost always have more than one comorbidity.
6. Jassat:

Comorbidities associated with #COVID19 hospital admission = change with age.

For people between 20-39 years (sexually reproductive years) HIV = most common comorbidity. For people of 40+ hypertension/diabetes = most common (lifestyle diseases = more common in 40+)
7. Jassat:

Ultimately, age is the strongest indicator of how sick you will get with #COVID19 - more so than any other comorbidity.

In SA, non-white people's risk of death of COVID = higher than white people's

🧵1.What's happening with #COVID19 infections in SA?

@Dr_Groome, @nicd_sa:

- Our #Omicron wave is over
- There was a small uptick when schools and colleges opened and restrictions were also eased, but infections are now down to "in between wave" levels
2. What version of #Omicron is dominant in SA?

@Dr_Groome:
1. BA.2 (the version that's now spreading around the world, as opposed to BA.1, the original version)
2. BA.2 (dark orange on pie charts) = more transmissible, but SA data shows it doesn't make people sicker than BA.1
3. These graphs show how SA's #COVID19 cases have decreased (top) and how the BA.2 version of #Omicron has increased/spread (bottom).

🧵1. How many #COVID19 jabs does SA have?

#JoePhaahla:
1. 20 million+ vaccine doses in stock
2. There's been an increase in take-up over the past week
3. But there's still a risk that 100,000 doses that will expire on March 31 won't be used in time + need to be discarded
2. #JoePhaahla:
1. SA is working with #COVAX to take up doses in SA that risk expiry before use and then return them later (so a kind of exchange programme)
2. Programmes right now specifically target the 18-34 age group where uptake is the lowest
3. Nicholas Crisp, @HealthZA:
More exact count of nr of #COVID19 doses in SA: 25 mil doses
- 13 mil = #Pfizer
- Pfizer = more difficult to store than #JnJ - once removed from low temperatures = limited shelve life
- All JnJ doses only expire in 2023

🧵1. Will SA vax kids between 5 + 11 years @ #COVID19?
- The vax MAC = not made a recommendation 2 @HealthZA. @SAHPRA1 = not approved vax 4 this group yet
- But if they say "yes" = no money 2 buy the jabs. Kids jabs = different from adult jabs. We can't use the ones we've got.
2. Do other countries vaccinate kids between 5 + 11 @ #COVID19?

- Just over a quarter of kids between 5 + 11 = vaxxed in the US
- UK = vaxxing vulnerable kids (for now)
- Sweden = only vaxxing kids vulnerable to respiratory diseases
- Full story: bit.ly/3JVGmzu Image
3. What about our current #COVID19 vax stock?
- In total we've got 27 million doses
- 400,000 #Pfizer doses will expire on March 31
- 7 million #Pfizer doses will expire in June/July

BREAKING [Thread]
From Wed, 23rd Feb, you can:
1. Get a 2nd #Pfizer jab 21 days after a 1st jab (previously = 42 days)
2. Get a Pfizer booster (3rd jab) 3 mnths after a 2nd jab (previously = 6 months) or choose 2 have a #JnJ booster after 2 #Pfizer shots (boosters = only for 18+)
2. From TOMORROW, Mon, 21st Feb, people of 18+ who received 1 #JnJ jab can:
- Choose to have a #Pfizer booster (instead of a 2nd #JnJ shot [booster] after 1 JnJ shot), in other words, you'll be able to "mix and match"
3. What should you do if a site has only 1 brand of #COVID19 vaccine available?

@HealthZA:
1. You should go with the same jab that you got 4 vaccination as a booster (or look for a different site)
2. Homologous boosting (booster = same as your other doses) = preferred
