The novel coronaviruses, known as SARS-CoV and SARS-CoV-2, have had a seismic impact on global health. They've caused two pandemics, SARS in 2002 and COVID-19 in 2019.
In late 2019, a city in China, Wuhan, became the epicenter of the latter pandemic. This virus, SARS-CoV-2, has now infected millions across the globe and caused a significant number of deaths.
A lot of focus has been placed on the zoonotic origins of these viruses. SARS-CoV is believed to have probably originated from bats and spread through masked palm civets to humans.
Similarly, SARS-CoV-2 was thought to have been transmitted from bats to humans through an unknown intermediary animal. Further research is being conducted to validate this theory.
The World Health Organisation (WHO) has been spearheading global efforts to curb these pandemics
During the SARS outbreak, aggressive surveillance measures were quickly implemented, and the epidemic was contained in just over eight months.
However, the COVID-19 pandemic presented a different scenario. Despite WHO's rapid response, the virus had already spread globally.
To control the pandemic, the WHO advised various measures including social distancing, wearing masks and hand hygiene, along with clear communication regarding the disease among nations.
The role of scientific research in combating the virus has been unprecedented.
Multiple frameworks to analyze the virus, understand its transmission dynamics, and to find effective treatments were initiated.
As a result, within a year, multiple vaccines were developed, approved, and distribution was started globally to immunize vulnerable populations.
But, some challenges such as vaccine rationing and unequal distribution among countries still need to be addressed to achieve global herd immunity.
The novel coronavirus has opened up discussions on public health capabilities.
Despite WHO's efforts, the pandemic has shed light on the insufficient global health infrastructures which have been unprepared to respond effectively.
To prevent future pandemics, strategic planning in strengthening health systems, enhancing surveillance measures and prevention capabilities are vital.
Funding and resources should be made available to enhance health systems, especially in countries with poor health infrastructures.
Furthermore, the socio-economic impacts of pandemics cannot be underestimated.
The COVID-19 pandemic has led to significant economic challenges worldwide. Many countries have fallen into recession as a result.
More concerning is the increase in poverty and inequality. With numerous job losses, many people are facing financial hardships.
Additionally, countries should implement strategies to recover economically from the pandemic and to protect their citizens from such crises in the future.
In conclusion, addressing several measures is necessary to prevent future pandemics.
Identifying zoonotic diseases early, strengthening health systems, rapid vaccine production, and equitable distribution are key.
Furthermore, preparing for socio-economic impacts is also equally vital. Only through global co-operation can we hope to effectively combat such pandemics in the future.
Lastly, with the experienced gained from handling current and past pandemics, the world should be better prepared to face future health crises.
