LETTERS: THE World Health Organisation (WHO) defines public health as "the art of applying science in the context of politics so as to reduce inequalities in health while ensuring the best health for the greatest number".
Unlike other specialties in the field of medicine, public health is an abstract concept, rendering its contributions and achievements unnoticed.
Whether we realise it or not, we experience public health initiatives right from the time we wake up and go about our daily grind.
Some noteworthy examples are:
1. The provision of clean and fluoridated water to promote physical and dental health;
2. The provision of proper sanitation and waste water treatment to prevent the spread of infections;
3. The fortification of food and ensuring its safety and quality to prevent nutritional deficiencies in the population and the consumption of hazardous chemicals;
4. Road safety measures to prevent commuting accidents.
5. Prescribing and enforcing Occupational Safety and Health (OSH) policies to ensure that workplaces are safe spaces in terms of physical and mental wellbeing.
Overall, public health measures in our country have led to increased life expectancy, a decrease in infant and maternal mortality rates, and better access to healthcare.
These silent victories are celebrated boisterously in the hearts of those working behind the scenes to keep Malaysia safe.
However, on certain occasions, such as the current Covid-19 pandemic, the function of the field of public health becomes more visible, and the accomplishments more tangible.
Through the application of clinical epidemiology, biostatistics, evidence-based outbreak management principles and collaborative partnerships, our nation has managed to keep the Covid-19 situation under control.
The photo with the article showcases part of our dedicated public health team in front of UMMC's Covid-19 Crisis Command Centre. Albeit socially distanced, we remain committed to our cause. Our operations may be confined to an office space but the impact of our work transcends borders.
Our workspace is akin to a mini Malaysia where we celebrate unity within diversity and work together in harmony.
We rely on each other to achieve our goals.We trust each other to maintain the sanctity of our workplace. Most importantly, we remind each other daily why everything we do is worth it.
