Doctors, scientists and heroes working on the frontline have all learnt so much in the past four months, and it is these learnings that are making all the difference in South Africa’s fight against COVID-19!


South Africa (15 July 2020) – Dr Mark Holliday, a General Practitioner in a large group practice in South Africa, has shared some insight that is both incredibly positive and hopeful in the fight against COVID-19.

Anxiety, stress levels, rumours and unhelpful personal theories have all shot up proportionately. But the information vacuum is being filled with more and more dependable and positive scientific information from trustworthy sources – as well as personal experiences of the virus as it increasingly hits closer to home.

This is good news!

“We’ve come a long way fast since March 5th, 2020. On that day, the first COVID-19 patient had much to fear. Then, very little was known about the contagion, and the limited data and scientific ambiguity made it difficult for the medical profession to confidently treat the virus with any certain belief of a positive outcome.”

“This July, we know a lot more. Thanks to the load on our northern hemisphere and Western Cape colleagues, today’s COVID-19 patients benefit greatly from the worlds experience and the short four months of steep collective learning.”

Here are all the good things that Dr Mark Holliday points out for South Africa and the world!

Lung Disease

Not all cases in respiratory distress have pneumonia or lung infections. A significant proportion of people who would have died on ventilators are now recognised as having a clotting disorder that blocks the blood vessels feeding the lungs, thereby causing shortness of breath. We also have a whole new generation of anti-clotting drugs that can help these patients as well as those whose clots are affecting other organs.


We have pulse oximeters readily available that can be used to home monitor any decline in a patient’s oxygen levels. This means that we can action more advanced treatments cheaply much sooner than before. We have learnt that laboratory tests such as LDH, CRP and D-Dimer can usefully predict downward trends patients.


The provision of Oxygen to severely ill patients remains the cornerstone of advanced patient care. Mass nursing facilities such as Nasrec have being prepared for this purpose. ICU treatment is no longer the cut and paste approach of putting patients on a ventilator with a previous 50% mortality rate. We have new alternate ways of oxygenating the severely sick; prone nursing (face down) and high flow techniques of oxygenation can perfuse compromised lungs without ventilators.


Anti-clotting treatments and steroids (such as Dexamethasone) are now a regular part of the ICU doctor’s weaponry to combat the Cytokine storm. Another old drug, Colchicine, has recently been shown to help prevent micro clots in the lungs. GP’s more experienced with Covid-19 are starting to apply these medicines at home to prevent the need for hospitalisation.

Drugs old and new

Many drugs have been tried to treat COVID-19, and we now have experience of what does and does not work. Quinine based drugs and Zithromax in high doses have no place in ICU’s. New drugs such as Avigan and Remdesivir have been proven to shorten ICU stays by up to four days. Anti-inflammatories such as Ibuprofen and ACE inhibitors, originally considered dangerous have now been given a clean bill of health. Observational studies have suggested certain drug categories such as PPI’s are associated with worse outcomes. Recent evidence has demonstrated that the hormone Melatonin in high doses may be beneficial. Knowledge changes daily in this epidemic as new information evolves.

Home treatment

Community resources such as General Practitioners (GPs) have collaborated to share knowledge and experience to provide the latest in care for an overburdened health system. Casualties and hospitals are scary places for patients, and our GPs have risen to the challenge; these doctors constitute the primary interface with patients. Virtual forums and webinar lectures actively keep GPs abreast of new information and treatments. GP’s have developed effective preventative strategies that are readily available, and they bravely deal with Covid-19 patients face to face. Some have already succumbed to the infection themselves.


We are recognising early specific symptoms peculiar to COVID-19 such as loss of taste and smell, COVID-19 toes and chilblains, specific rashes, conjunctivitis and cold sores. This knowledge gives us a head start in recognising, testing, treating, isolating and quarantining our patients.

Shorter Quarantine

New evidence suggests that the virus is not shed beyond day eight of an infection. If confirmed, this will be good news and will shorten the duration of isolation and quarantine. Amended guidelines will hopefully follow soon.

Better Tests

New tests have just been approved in South Africa that will be able to confirm those who are immune. A new instant breathalyser type test is starting production, which will give instant results in acute infections.


The unknown, conspiracy theories, flaky news and the media hype have all helped to fuel significant human fear for the past few months.

Anxiety, stress levels, rumours and unhelpful personal theories have all shot up proportionately. But the information vacuum is being filled with more and more dependable and positive scientific information from trustworthy sources – as well as personal experiences of the virus as it increasingly hits closer to home. Most GP’s are knee-deep in the fray and are now far better equipped to diagnose and treat COVID-19 cases than a few months back.

And the chances of beating COVID-19 now are much better than they were in March.
