Math and Science Join Forces to Tackle COVID-19

COVID-19 has been a tough opponent for the world. It's not just about vaccines and medicines anymore. Researchers have come up with a new way to fight it. They've created a fancy model called SEI1I2I3QCR. This model is not your average math problem. It uses something called fractional-order delay differential equations. These equations help to understand how COVID-19 spreads over time and why it has ups and downs. The model shows that time delays and fractional orders are super important in controlling the disease. The researchers didn't stop at just creating the model. They also used something called optimal control theory. This helps to figure out the best ways to control the spread of COVID-19 without using medicines. Things like quarantines and awareness campaigns can make a big difference. The model was tested with real data from China. It matched up well, showing that this new approach could be a game-changer. The model suggests that using time delays and fractional calculus can give us a new way to manage pandemics. It's all about finding the right balance and using the right tools. This could lead to more effective and cost-friendly ways to handle outbreaks in the future. It's a reminder that math and science can work together to solve real-world problems. The model also shows that we need to think beyond just medicines and vaccines. It's about understanding the disease and using that knowledge to make better decisions. This is a big step towards being ready for future pandemics.
