Prof Robert Bragg
Prof Robert Bragg is a researcher in the Department of Microbiology and Biochemistry at the University of the Free State (UFS) and believes hospital-acquired infections (HAIs) might already be “Disease X”.

During the World Governments Summit, the World Health Organisation (WHO) warned world leaders about the likelihood of a Disease X outbreak, saying it is “a matter of when, not if” a new pathogen and pandemic will strike. If there is an outbreak of this disease tomorrow, the world still would not be ready. 

During his speech earlier this month at the summit in Dubai, Tedros Adhanom Ghebreyesus, Director-General of the WHO, said COVID-19 was a Disease X – a new pathogen causing a new disease. He said: “There will be another Disease X, or a Disease Y or a Disease Z. And as things stand, the world remains unprepared for the next Disease X, and the next pandemic. If it struck tomorrow, we would face many of the same problems we faced with COVID-19.”

Though Disease X is a hypothetical placeholder representing yet-to-be-encountered pathogens, Prof Robert Bragg, researcher in the Department of Microbiology and Biochemistry at the University of the Free State (UFS), believes hospital-acquired infections (HAI) might already be “Disease X”. He says data shows that deaths from HAIs will become the leading cause of human deaths. This problem is rapidly growing as most of the pathogens which people contract while in hospital are now resistant to antibiotics, making them very difficult to treat.  

Prof Bragg, whose main research is in disease-control, first in the agricultural industry, and now human health, also previously warned about a disease that would make COVID-19, which killed more than seven million people to date globally, look like a dress rehearsal. His PhD student, Samantha Mc Carlie, investigating how bacteria become resistant to disinfectant and sanitiser products. This is a serious problem for the future, as disinfection could be our last line of defence.

Heading for a crisis in health care

“The world is rapidly heading for a crisis in health care regarding hospital-acquired infections. It is common knowledge that we are quickly running out of antibiotics (and antifungals) to treat bacterial and yeast infections. Without antibiotics and antifungals, the outcome of many of these bacterial and yeast hospital-acquired infections will be very severe. They will, unfortunately, in many cases, result in the death of the patient,” says Prof Bragg. 

According to him, the WHO suggests that 30% of patients in ICUs in developed countries and 70% in underdeveloped countries will contract a HAI. Of these, the mortality rate can be as high as 70%. 

“Most of these infections are caused by multiple drug resistance strains of bacteria such as Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species. Additional bacteria and yeast, which can also cause HAIs, such as Serratia species, are also becoming a concern due to their intrinsic higher levels of disinfectant resistance.”

Prof Bragg explains that in 2014, a high-profile review was first published, commissioned by the UK Prime Minister, entitled, “Antimicrobial Resistance: Tackling a crisis for the Health and Wealth of Nations” (the AMR Review). This review estimated that antimicrobial resistance (AMR) could cause 10 million deaths annually by 2050 (The Review on Antimicrobial Resistance 2016). This is the same number of deaths caused by cancer today, making AMR the leading cause of human mortality by 2050. When it was finalised, this report was highly criticised as an over-dramatisation, as when this prediction was made, the number of mortalities related to HAIs was around 700 000 – a very long way off 10 000 000. However, according to recent estimates, five years later, in 2019, 1.27 million deaths were directly attributed to drug-resistant infections globally, and this had reached 4.95 million deaths associated with bacterial AMR (including those directly attributable to AMR) by 2022 (Murray et al. 2022). 

The overuse of disinfectants during the COVID-19 pandemic, according to Prof Bragg and Mc Calie, has contributed to the crisis by fostering resistant strains and contaminating environments. Based on the current trajectory of mortalities, the 10 million mark will be reached way before 2050.

Need for a paradigm shift

The researchers say an urgent need to change the paradigm in medicine from “treatment” to “prevention” is necessary and that the old saying ‘prevention is better than cure’ has never been truer. 

According to Bragg: “The golden era of antibiotics is rapidly coming to an end. It is highly unlikely that we will discover new antibiotics, and even if we do, the likelihood that the bacteria will already have or will be able to develop resistance in a very short time is highly likely. 

“We need to think of what happed with quinolones, where we thought we had won the war with a groundbreaking new antimicrobial agent. The bacteria did not have millions of years of evolution to develop resistance to quinolone, yet in only three years, the first resistant bacteria were isolated. There is currently great excitement around AI-derived new antibiotics. However, the end result is likely to be the same. We need an alternative to treatment – in other words, a paradigm shift.” 

Improved biosecurity 

Prof Bragg says highly improved biosecurity is the only viable option for disease control in a post-antibiotic era. By using good biosecurity in poultry production, he says the mortality rates were reduced by 50%. 

Research has shown a direct link between the environmental microbial load in a hospital and HAIs; with a lower microbial load linked to lower incidence of HAIs including C. difficile infections (Boyce et al. 2008; Suleyman et al. 2018; Umemura et al., 2022). Therefore, the new paradigm is to reduce microbial contamination in the hospital environment to prevent HAIs. If there are fewer dangerous microorganisms in an environment, patient and staff exposure to these microorganisms will decrease, reducing the level of HAIs for staff and patients. However, to reduce the microbial loads in healthcare settings, effective cleaning and disinfection products need to be used.

Situation on the Bloemfontein Campus, and letter to parents
2016-02-28

Letter to parents from Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS 

 

Statement by Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS) about the situation on the Bloemfontein Campus


1.    As all of you know, last night we witnessed a really tragic event at Xerox Shimla Park on the Bloemfontein Campus on the occasion of the Varsity Cup rugby match between NMMU (FNB Madibaz) and UFS (FNB Shimlas).
2.    The game started at 18:30 and about 17 minutes into the match, a group of protestors sitting on the north-eastern side of the stadium decided to invade the pitch and disrupt the game in progress.
3.    After a short while, some of the spectators also invaded the field, chasing and brutally beating those protestors whom they caught.
4.    As a university leadership we condemn in the strongest terms possible the vicious attack on the protestors. Nobody, repeat nobody, has the right to take the law into their own hands. While the protests were illegal and disruptive, it did not harm to the physical well-being of the spectators.
5.    The reaction from the group of spectators, however, not only opened old wounds, it trampled, literally and figuratively, on the dignity and humanity of other human beings. This we condemn in no uncertain terms, and no stone will be left unturned to find those who acted so violently on what should have been a beautiful occasion that also brought families and young children together to enjoy an evening of sport.
6.    I cannot over-emphasise our level of disgust and dismay at the behaviour of the spectators. It is NOT what the University of the Free State (UFS) is about and we are working around the clock to gather evidence on the basis of which we will pursue both charges and, in the case of students, also disciplinary action on campus.
7.    At the same time, the invasion of the pitch is also completely unacceptable and we will seek evidence on the basis of which we will act against those who decided to disrupt an official university event.
8.    Clashes between students occurred afterwards on campus and members of the Public Order Policing had to disperse some of them. The situation was stabilised in the early hours of the morning.
9.    Disruption continued this morning (23 February 2016) when students damaged some university buildings, a statue, and broke windows. Additional reinforcements from the South African Police Service were brought in to stabilise the campus. Additional security has also been deployed.


Broader picture
10.    We are very aware of the national crisis on university campuses and the instability currently underway. While the UFS has been largely peaceful, we have not been spared this turmoil, as last night’s events showed.
11.    We are also conscious of the fact that even as we speak, various political formations are vying for position inside the turmoil in this important election year. In fact, part of the difficulty of resolving competing demands is that they come from different political quarters, and change all the time.
12.    We are therefore learning from reliable sources that the Varsity Cup competition is, in fact, a target of national protests in front of a television audience.
13.    And we are aware of the fact that these protests are not only led by students but also by people from outside who have no association with the university. Just as the violent spectators involved on Monday night also included people from outside the university.

The demands

14.    My team has worked around the clock to try to meet the demands of contract workers demanding to be in-sourced. In fact, this weekend past, senior colleagues sat with worker leaders in the township to try to find ways of meeting their demands. We were hoping that such an agreement would be finalised by Monday afternoon (22 February 2016), but on the same Monday morning workers and students were arrested after moving onto Nelson Mandela Avenue, after which the South African Police Service (SAPS) took over as the matter became a public safety concern outside the hands of the university. Since then, it was difficult to return the workers to settle on a possible agreement.
15.    The fact is that the UFS has been in constant negotiation with contract workers to provide our colleagues with a decent wage and certain benefits. In fact, towards the end of last year we raised the minimum wage from R2 500 to R5 000. We were in fact hoping that the continued negotiations would improve that level of compensation even as we looked at a possible plan for insourcing in the future. We made it clear that if we could insource immediately, we would, but that the financial risk to the university was so great that it threatened the jobs of all our staff. Those negotiations were going well, until recently, when without notice the workers broke away and decided to protest on and around campus.
16.    While these negotiations were going on, the Student Representative Council (SRC) on Monday 22 February 2016 also decided to protest. While the vast majority of our 32 000 students were in classes and determined to get an education, a very small group led by the SRC President decided to protest; some invaded the UFS Sasol Library and the computer centre, and with the President eventually made their way to Xerox Shimla Park on which route they confronted the police, interrupted traffic and in fact injured some of our security staff as well as police officials.
17.    The university is definitely proceeding to collect evidence on these illegal and violent acts and will also act firmly against students involved in these protests.

Summary
18.    The events of Monday night represent a major setback for the transformation process at the UFS. While we have made major progress in recent years—from residence integration to a more inclusive language policy to a core curriculum to very successful ‘leadership for change’ interventions for student leaders—we still have a long way to go.
19.    One violent incident on a rugby field and we again see the long road ahead yet to be travelled. As I have often said before, you cannot deeply transform a century-old university and its community overnight. We acknowledge the progress but also the still long and difficult path ahead. We will not give up.
20.    We have 32 000 students on our campuses; the overwhelming majority of them are decent and committed to building bridges over old divides as we have seen over and over again. So many of our students, black and white, have become close and even intimate friends working hard to make this a better campus and ours a better community and country. Like all of us, they are gutted by what they saw on Monday, but the hundreds of messages I received from parents, students, and alumni this past 20 hours or so said one thing—keep on keeping on. And we will.
