How do Pandemics usually end? And how will the COVID-19 end?

The whole world is in the grip of COVID-19, and people are placing their hopes on a vaccine to eliminate it, the fact that most of the infections encountered by our ancestors are still with us. Let see some of the deadly pandemics which have struggled in the world and affected the different generations.

Bubonic Plague: A rare but serious bactarial infection that’s transmitted by fleas. The bubonic plague caused by the bacteria yersinia pestis. It can spread through contact with infected fleas. This pandemic was earliest recorded in 541 AD.

According to WHO’s academic research report, the plague has killed millions, and The plague of 1346-1353 is considered the deadliest outbreak of all. But few die today, the figure between 2010 to 2015 has reached 584.

It is believed the disease, which causes swollen and infected lymph nodes, called buboes, was finally brought under control by strict quarantining and improved sanitation, among other things.

In this concern, Steven Riley, professor of infectious disease dynamics at Imperial College London, says  “But none of this could have happened without an understanding of how transmission occurred, This is something that still applies today.”

Smallpox:  Smallpox is caused by infection with the variola virus. The virus can be transmitted directly from person to person. Direct transmission of the virus requires fairly prolonged face to face contact. It was earliest recorded in 1520.

Smallpox killed at least 350 million – no-one dies today.

The smallpox vaccine was introduced by a British doctor Edward Jenner in 1796. the disease has been completely eliminated – although it took nearly two centuries to do so.

Prof Riley regards this feat as one of the greatest achievements of mankind – rivalling the Moon landings.

HIV/Aids: HIV causes AIDS and interferes with the body’s ability to fight infections. The virus can be transmitted through contact with infected blood, semen and vaginal fluids.

HIV/AIDS takes too much length of time to show its symptoms and its high fatality rate, because it spreads fast and people don’t necessarily know they have it. Though it doesn’t have any vaccine or cure.

As per the research figures by WHO, an estimated 690000 people died of HIV/AIDs in 2019.

HIV could be regarded as an “worst case scenario virus”, says Prof Riley.
