Always Be Ready
One big lesson from COVID-19 is that we must always be ready for new diseases. History has shown that new outbreaks will happen—it's just a matter of when. Dr. Saggar says we have to stay alert and plan ahead to reduce the impact of future outbreaks. "We need to stay aware and be prepared," he explains, saying that this is important for both doctors and public health officials.
Investing in Science and Public Health
COVID-19 showed us how important it is to keep supporting research and public health. "For many of us, this was the biggest event of our careers," says Dr. Saggar. He stresses that we need to keep training new doctors, scientists, and health experts to stay ahead of future diseases.
The pandemic also proved that sharing information quickly is key. When doctors first reported COVID-19, researchers all over the world worked together to find ways to diagnose, treat, and prevent the disease. "Because we shared information, we were able to create vaccines and medicines faster than ever before," Dr. Saggar explains.
How COVID-19 Has Changed
Over the last five years, COVID-19 has changed from a new virus into something we now live with all the time. Most people have had COVID-19 or received a vaccine, which means the virus doesn't make as many people seriously sick anymore. "It's not the same threat it once was," says Dr. Saggar. "Thanks to vaccines, medicines, and natural immunity, the virus is not as dangerous for most people."
However, COVID-19 is still around and spreads throughout the year, unlike the flu, which is mostly seen in the colder months. Scientists track it by checking wastewater (sewage) to see how much virus is present. While many people still catch it, far fewer need to go to the hospital compared to earlier years.
What's Next?
Even though COVID-19 is less of a threat for most people, those with weak immune systems are still at risk. Dr. Saggar says we need to keep researching ways to protect them. Right now, scientists are studying new medicines, including antiviral drugs and antibody treatments, to help those who are most vulnerable. "High-risk people still need protection, and we must keep working on better treatments," he explains.
A Big Achievement
Despite all the hardships, Dr. Saggar says we should recognize how much progress has been made. "Yes, mistakes happened, but in the end, millions of lives were saved thanks to safety measures, vaccines, and treatments," he says.
As we look ahead, the lessons from COVID-19 will help us prepare for the future. Staying ready, working together, and continuing research will be key in fighting future outbreaks. Five years later, the pandemic has changed—but we are now better prepared for whatever comes next.
