In the past century, the largest gains in human health and life expectancy have come from public-health interventions, not medical ones. Clinical medicine — treating individual patients with medication and procedures — has registered enormous gains. Hepatitis C is now curable; so are many childhood cancers. Cutting-edge gene therapies are curing rare genetic disorders, and new technology is making surgeries of every kind safer. But even stacked against those triumphs, public health — the policies and programs that prevent entire communities from getting sick in the first place — is still the clear winner. “It’s saved the most lives by far, for the least amount of money, but why in avablity of so advance health tech still humans are losing the battle against a virus (COVID-19).
This covid 19 became a one of the biggest challenge for human kind , after so long shutdown of entire world , almost all country economy collapes , nearly 15 million infected and 602 k death due to covid -19 still their is no conformed cure/ vaccine. with 1st case in China (in wuhan city ) in december 2019 and sepred across the World with increase in multiple rate of pesents and became a world pendamic.
what is COVID-19 ?

On 31 December 2019, the World Health Organization (WHO) got reports from health authorities in China of a clster cluster of viral pneumonia cases of unknown cause in Wuhan, Hubei,and an investigation was launched at the start of January 2020. On 30 January, the WHO declared the outbreak a Public Health Emergency of International Concern (PHEIC)—7,818 cases confirmed globally, affecting 19 countries in five WHO regions.(PHEIC)—7,818 cases confirmed globally, affecting 19 countries in five WHO regions.
Several early infected people had visited Huanan Seafood Wholesale Market; the virus is therefore thought to be of zoonotic origin.The virus that caused the outbreak is known as SARS‑CoV‑2, a newly discovered virus closely related to bat coronaviruses, pangolin coronaviruses, and SARS-CoV. The scientific consensus is that COVID-19 has a natural origin. The probable bat-to-human infection may have been among people processing bat carcasses and guano in the production of traditional Chinese medicines.
The earliest known person with symptoms was later discovered to have fallen ill on 1 December 2019, and that person did not have visible connections with the later wet market cluster. Of the early cluster of cases reported that month, two-thirds were found to have a link with the market. On 13 March 2020, an unverified report from the South China Morning Post suggested a case traced back to 17 November 2019 (a 55-year-old from Hubei) may have been the first person infected.
The WHO recognised the spread of COVID-19 as apandemic on 11 March 2020as Italy, Iran, South Korea, and Japan reported surging cases. The total numbers outside China quickly surpassed China’s.
world Health system fail ?
Covid-19 is a catastrophic failure of public health leadership. Highly-qualified people — from the World Health Organisation, the US Centres for Disease Control, the US National Institute of Allergy and Infectious Diseases, and eminent epidemiologists from institutions such as Stanford, Harvard, and Johns Hopkins — are offering regular updates on TV about what needs to be done. While viewers appreciate their expertise and measure of calm, billions around the world are now impacted by their collective failure to act and prevent this epidemic from happening in the first place.
Bill Gates, in a famous TED talk in 2015, predicted that the world is totally unprepared for a pandemic, and warned that countries have to mobilise. “Today, the greatest risk of global catastrophe doesn’t look like this,” he said, showing the image of a mushroom cloud created by a nuclear explosion. “Instead, it looks like this,” he said, pointing to a picture of the influenza virus. Why were public health officials not paying attention to Gates?
Every major country has a generous, dedicated budget for public health. Public health officials have been studying epidemics and pandemics for hundreds of years. After all, more people have died because of contagion from diseases like the plague or the Spanish flu than from war, and these experts have been combing through troves of data, often with the help of supercomputers, to find cures or vaccines for infectious diseases. Despite all the resources at their disposal, they are now saying that a Covid-19 cure is months away, and a fully-tested vaccine after clinical trials, perhaps a year and a half away. Didn’t they see something like this coming at all?
