South African doctors are tough. We are used to extreme conditions. Making do with little. Going the extra mile for our patients. We have faced surge after surge of trauma patients hit our depts every weekend, managing the wounded, bleeding, critically injured. A thread 1/

I trained in the early 2000s. When SA didn't have ARVs for patients dying with HIV/Aids. In 2003 as a med student we marched so that South Africans could have access to ARVS. Millions of South Africans died due to the slow rollout of ARVS in the early 2000s 2/
As an intern, as ARVs were just being initiated, countless patients died - too sick to be started on ART, it was too late. As an intern at Bara, I remember certifying 8 patients dead in a night. Some patients were my own age - 24. 3/
ARVs made a huge difference. Life expectancy increased. Child-headed households decreased. More patients living a normal life. The #Covid19SA pandemic has reminded me so much of that pre-ARV era - the helplessness, being overwhelmed with patients and lacking resources 4/
Although we always get nervous when being exposed to HIV, we feel reassured that there ART prophylaxis. With #COVID19 HCWs are at high risk of getting sick, and also severe illness. We have continued to face this fear all year 5/
We have continued to work in an overburdened healthcare system, doing our best. Yet not even the PPE we are given has been of an acceptable standard. This article looked at N95s given to SA HCWs and found them SUBSTANDARD. 6/ https://t.co/Gg4KBK0pXK
Aerosolisation of #COVID19 has been proven to be a major concern. We don't have negative pressure rooms. We work in poorly ventilated departments overcrowded with patients. We are at high risk of getting sick with covid-19. Yet we don't have masks that fit properly 7/
Given our working environment, our poorly fitting masks, our second wave that is surging beyond the peak of the 1st wave, the need to reopen the economy to tourists, South Africa needs to make getting the #covid19vaccine its UTMOST PRIORITY. 8/
South African Healthcare Workers MUST hold @HealthZA accountable. We need the vaccine NOW, as we face our second wave. Getting the vaccine mid-year is TOO LATE for us and our patients. 9/
Let's not forget how long it took to get anti-retrovirals to patients with HIV/AIDS in South Africa. I will never forget what we went through back then. Delaying the covid19 vaccine is the same thing. 10/10 end

You gotta think about this one carefully!

Imagine you go to the doctor and get tested for a rare disease (only 1 in 10,000 people get it.)

The test is 99% effective in detecting both sick and healthy people.

Your test comes back positive.

Are you really sick? Explain below 👇

The most complete answer from every reply so far is from Dr. Lena. Thanks for taking the time and going through


You can get the answer using Bayes' theorem, but let's try to come up with it in a different —maybe more intuitive— way.

👇


Here is what we know:

- Out of 10,000 people, 1 is sick
- Out of 100 sick people, 99 test positive
- Out of 100 healthy people, 99 test negative

Assuming 1 million people take the test (including you):

- 100 of them are sick
- 999,900 of them are healthy

👇

Let's now test both groups, starting with the 100 people sick:

▫️ 99 of them will be diagnosed (correctly) as sick (99%)

▫️ 1 of them is going to be diagnosed (incorrectly) as healthy (1%)
