[Thread] 1. SA saw its 1st confirmed #monkeypox case last week. Will there be more cases? YES. Why? The 1st case doesn’t have a travel history so he (a 30 year old man from Jhb) contracted it from someone in SA who already had it. bit.ly/3QNA7SH
2. How do you get #monkeypox? Through close contact, e.g. hugging, kissing, sex, or contaminated materials, e.g. shared linen or cutlery. It’s much harder to contract monkeypox than #COVID19. The @nicd_sa's Jackie Weyer explains it in this sound clip:
3. What’s the most telling #monkeypox symptom? Blisters on your skin. The blisters don’t have to be all over your body, they can, for instance, just be on your genitals, hands or face. The @nicd_sa's Jackie Weyer explains in this sound clip:
4. What test is used to confirm #monkeypox? A PCR test — the same type of lab test that’s used for #COVID19 (lab technicians obviously look for the monkeypox virus and not #SARSCoV2, but they use the same technique). bit.ly/3QNA7SH
5. Do health workers take swabs to test you? Yes. They take the swabs from the blisters on your skin. (For #COVID19 they take swabs from your nose). bit.ly/3QNA7SH
6. For how long are you infectious with #monkeypox? Until all the blisters on your skin have healed (when new skin has grown over the blisters, they’ve generally healed — it's through contact with the open skin on the blisters that the virus spreads). bit.ly/3QNA7SH
7. Is there a vaccine for #monkeypox? Yes. The smallpox jab provides 85% protection against monkeypox infection. But SA stopped giving the jab in the 1980s, so only people of 42+ in SA have that protection. bit.ly/3QNA7SH
8. How many countries currently have #monkeypox cases? The WHO says there are 3,000+ cases in 47 countries, many of which have never previously reported the disease. But it's not considered a global health public health emergency like #COVID19 and #polio. bit.ly/3xPaMz6
9. Most #monkeypox cases are currently among men who have sex with men. Are they biologically more susceptible to #monkeypox? NO. The only thing that can make you less susceptible is vaccination. bit.ly/3QNA7SH
10. Why are #monkeypox cases mostly among men who have sex with men if they're not biologically more susceptible? It's the group where the 1st cases started. There are strong social networks within the MSM community, so transmission followed that route. nyti.ms/3Nq2H9U

[Thread] JUST IN:
1. @healthza has confirmed that #JoePhaahla has repealed regulations 16A, 16B + 16C in section 90 of the National Health Act. What does this mean?
In short:
1. No masks
2. #COVID19 gathering rules = dropped
3. COVID entry requirements into SA = dropped
2. What does regulation 16 A say?
- You must wear a mask indoors
- You must wear a mask when using public transport

This has been repealed, so you no longer:
- Have to wear indoor masks
- Have to wear masks when using public transport
3. What does regulation 16 B say?
- You need to be vaxxed 4 certain gatherings/produce proof you tested negative 4 #COVID19
- There are nr limits on people attending a gathering if = not vaxxed/test negative

This has been repealed, so these rules 4 gatherings = no longer valid.

🧵JUST IN: 1. From Mon, 6 June, people of 50+ can get an extra #Pfizer #COVID19 vaccine booster 120 days after their previous booster. Technically, you can already get one from tomorrow (Sat), as the #EVDS went live tonight, but you’ll only receive an sms alert from Mon.
2. Can you choose if you want an extra #JnJ or #Pfizer booster? No. For this round, you'll need to take a #Pfizer booster (all SA’s #Pfizer jabs will have expired by the end of Oct, so this is one way of using them faster before then).
3. If you had #JnJ as a 1st dose:
- 2nd dose (JnJ/#Pfizer) = 60 days after 1st shot
- 3rd dose (booster, JnJ/Pfizer) = 90 days after 2nd dose
- 4th dose (booster, Pfizer, the one that kicks on Mon) = 120 days after 3rd dose Image

🧵1. It used to be straightforward to determine when we were in a #COVIDinSA wave. Everyone used the ministerial advisory committee’s formula. In 2022, things are a bit more complicated. Some researchers argue this method is no longer all that useful. bit.ly/3wkRRwv
2. If we use the MAC formula, the fifth wave started on May 7. But since these numbers alone no longer translate into curfews, lockdowns or liquor bans, @nicd_sa researchers believe a new benchmark may be necessary. bit.ly/3wkRRwv
3. The @nicd_sa's @Dr_Groome says #COVID19 case numbers have become less meaningful — using them to calculate a wave, even more so: “Severe outcomes like hospitalisations and deaths are better metrics to use now that we have seen the decoupling of cases and severe outcomes.”

🧵1. #JoePhaahla, #HIV:
- 8 million SAs = HIV positive in 2021
- Nr on #ARV's: 5.4 million, so there's a gap of over 2 million who are projected to be HIV positive but not on treatment.
- Main concern = spread amongst young people, especially young girls.
2. SA's policy = to provide #HIV treatment for everyone who tests positive to achieve viral suppression and reduce transmission.
3. #JoePhaahla:
- Our target is to scale-up #HIV treatment by another 700 000 this year to above 6 million people.
- Our treatment coverage of those who know their status has slipped to only 76% since #COVID19 Because of COVID we have missed on 90/90/90 target for 2020.

🧵1. BREAKING: @SAHPRA1 has approved a 3-month extension of the expiry dates of #Pfizer #COVID19 shots when stored at -70 °C. @HealthZA says it's stored the 92,370 jabs that originally expired on March 31 at -70°C, so they'll now only expire on June 30th and can still be used.
2. Why are there new expiry dates?

#COVID19 jabs have only been around for +/- 1.5 years. Manufacturers can only test if they stay stable 4 extended periods of time as the time moves on. They've now established that Pfizer jabs can be kept at -70°C for 12 (instead of 9) months
3. How many #COVID19 #Pfizer jabs does SA have left?
@healthza says on May 9:
10,593,060 doses

When do these jabs expire? (next tweet)

🧵1. Is SA in a 5th #COVID19 wave?
@ProfAbdoolKarim: It’s too early to tell. We don’t have reliable data 2 compare infections of the last 7 days with the previous 7 days. Why? SA = 2 holidays in the past week, so testing nrs = down + can’t reliably be compared 2 the previous wk.
2. Why do we need to compare data of the last 7 days with the previous 7 days?

- For a 5th wave the 7-day moving average would have doubled every 2-3 days (so we would have had 10,000+ cases by now)
- But we’ve seen only a 52% increase: from 3,097 (April 24) to 4,693 (May 1)
3. Does the lower-than-expected increase for a new wave mean we’re not in a 5th #COVID19 wave?

Not necessarily — it could just be that testing numbers are down because of the 2 public holidays in the past week (far fewer people go to test on public holidays).
