International One Health Day is held annually on 3 November. The goal of the day is to educate and increase awareness of One Health to encourage a collaborative effort between multiple disciplines, promoting the concept that the interactions between humans, animals, and the environment impact the health of people, animals, plants, and the environment.

The aptly named One Health Warriors, a student group comprising postgraduate students from the Division of Virology at the University of the Free State (UFS), was formed in 2016. The One Health Warriors annually participate in arranging a One Health event to celebrate International One Health Day. What is One Health? What zoonotic diseases should the public be aware of? How do zoonoses affect the healthcare provider? These are all questions that the student group addresses in their events.  

In 2022, the One Health Warriors targeted scholars to participate in their annual event. It is important for scholars to start learning about One Health from an early age, because most of them do not understand the importance of taking care of their pets. They are not always aware of the diseases that can be transmitted from animals to humans and how to protect themselves.

It is for this reason that postgraduate students from the Division of Virology took One Health awareness and science communication to the classrooms of Ratau Primary and St. Pauls Primary schools in Thaba Nchu, Bloemfontein. Grade 6 scholars were included in the events and a total of 224 learners participated in the day. 

According to Prof Felicity Burt, an expert in arbovirology in the Division of Virology and the National Health Laboratory Services (NHLS) – who holds an NRF-DST South African Research Chair in Vector-borne and Zoonotic Pathogens Research – and Tumelo Sekee, PhD student and research assistant in the School of Pathology, they decided to start with primary schools as they believe it is good to start teaching scholars from an early age to take care of their pets and understand the importance of One Health. 

Making the youth aware 

The focus was on making the youth aware of diseases transmitted from animals to humans, how to protect themselves from zoonotic diseases, and how to take care of their pets. They used role-play activities in which the learners were educated about the risk of contracting the rabies virus and some of the signs that may be shown by rabid dogs. The learners also got to learn about the importance of reporting any bites and getting appropriate treatment from the clinics.  

Rabies circulates within this area and is a high risk for children who play with stray dogs. They were advised about vaccines to protect their dogs against infection and thereby protecting themselves. They were shown how to remove ticks from the dogs, and the importance of not eating a dead animal whose cause of death is unknown. 

“The children were advised on the potential for tuberculosis (TB bovis) to occur in their livestock and the potential for spread to humans. Pictures were circulated among the learners showing them what a rabid dog or animal might look like and how an animal with TB bovis may present. The learners were taught about the importance of hand washing. In the finale of the event, the learners made a pledge to take care of their pets, and this was confirmed with painted hands on our One Health posters,” says Tumelo Sekee.

According to Prof Burt, One Health is an approach that recognises that the health of people is closely connected to the health of animals and their shared environment. One Health is not new, but it has become more important in recent years. “This is partly because many factors have influenced the way humans interact with animals (domestic and wild), plants, and our environment. These changes have led to the spread of known (endemic) pathogens and the emergence of novel pathogens and zoonotic diseases, which are diseases that can spread between animals and people. The recent pandemic is an example of how zoonotic transmission of a pathogen from wildlife to humans has a devastating public health impact,” explains Prof Burt.

Positive feedback
Sekee says the feedback was extremely positive; this may be because the communication was done in the learners’ mother tongue, Setswana, which made it easy for them to understand. Says Sekee: “There were many questions and discussions after the play, which suggested that the scholars showed interest in learning about a One Health approach. The scholars were also enthusiastic about participating in future events of the One Health warriors.”

The postgraduate One Health group previously also visited schools in Botshabelo and Bloemfontein, as well as farm workers in Kroonstad. They now plan to visit other schools in the Free State so that the One Health message can reach as many people as possible.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
