Biological and Chemical warfare what was Past and Future

The Chemical and Biological Warfare, fought over a decade, is beginning to evolve into a new paradigm. This war was not started in the 20th century. This war existed in ancient time and is being transformed into a new and newly way. Solon, (638-559 BC) used a strong laxative, the herb hellebore, having a high level of effect. During the Christmas siege in the 6th century BC, the Assyrians poisoned the enemy's sources with rye ergot and improved toxicity. In the Peloponnesian War (431-404 BC), they used another tactic of war, namely the Spartans threw a pitch and sulfur at the Athenians and their allies. The Middle Ages adopted another form of bio warfare, in which the invaders used dripping bodies with decomposed victims and disease as suitable “dirty bombs”. During the siege of Ca fa, in 1346 (modern-day in the Crimea), the Tartars' army was badly affected by the outbreak of the Plague. They threw the infected dead bodies on the city walls and in the city's canals and wells. Which leads to a pandemic due to the city's commitment. It is widely believed that victims of this terrible disease have fled the area, leading to the outbreak of the Black Death, which had killed at least a third of the European population over the years. On the other hand, Russian troops adopted the same lethal strategy against Sweden in 1710, which resulted in heavy casualties.  Another popular war strategy was introducing the Smallpox, by Francisco Pizarro (1476-1541) in which South American natives had given clothing items those were intentionally contaminated with a virus caused smallpox. Virus contaminated blankets and another clothing’s that induce smallpox and effected the opponents.  The General Jeffery Amherst (1717-1797) were donated or gifted Indians loyal to the French with smallpox-contaminated bedspreads during the French and Indian War of 1754 to 1767 which badly affect the whole system. As a result, epidemic had broken among the Native American escorts of Fort Carillon, due to which they lost it to the English. The current epidemic of COVID-19, which has crippled the world due to Coronavirus. Undoubtedly it was started in the city of Wuhan, but in a short time it is viral to almost every country, causing thousands of causality in every country. Some countries have suffered more than others due to the Coronavirus and long-term lock down. Economic growth was halted and unemployment rates skyrocketed. It is believed that the epidemic has had a worse impact on the under developing world than in developed nation. Some nations believed that the Coronavirus was also a human-caused disease and epidemic, while others insisted that it was a natural disaster. Science will prove in the near future whether it was natural or human made virus. Currently, there are new symptoms of the Omicron virus differently the severity of the disease is not clear so far according to the World Health Organization (WHO). Precautions are needed to avoid these germs that may be natural or man-made as biological warfare. There must be strict vigilance and new effective international laws to stop this biological warfare in order to save humanity. What is your opinion about COVID-19,  Is it natural or human made?
