For months the enemy of mankind has filled the world and occupied the whole world. The virus has so far infected more than 18 million people and has killed more than 680,000 people worldwide.

Several countries ’easing of quarantine measures has led to a new rise in the number of people infected with corona, which has opened the door to talk about a“ second wave ”of the pandemic.

This comes after the World Health Organization, on Tuesday, warned against being restrained in the face of the transmission of corona’s infection. “We are in the first wave,” said Margaret Harris, a spokeswoman for the organization. “It will be one big wave. It will vary somewhat, up and down, and the best thing to do is to flatten the wave and turn it into something weak that touches your feet.”

And last week, British Prime Minister Boris Johnson reported signs of a second wave of Corona’s outbreak, saying: “I’m afraid you are beginning to see signs of a second wave in some places.”

“We are still in the first wave”

However, experts and scholars disagree about describing the “second wave”. Some of them say that a new rise in the rate of injuries necessarily means “a second wave”, while others indicate that it is not a matter of waves but rather an increase in tests to include the largest number of people, which is accompanied by the number The height of the injured.

In this regard, the Washington Post reported that “it is too early to talk about a second wave.” It quoted scholars as saying that “we should not talk about this, because we are still in the first wave.”

“We are still in the first wave … With the easing of restrictions, new cases will emerge, but this cannot be portrayed as a new wave,” explained epidemiologist at Vanderbilt University Medical Center, Lauren Laporth.

Meaning of “second wave”

There is no formal scientific definition of a “second wave” in the viruses world, but it is often understood as “the re-emergence of new infections with the virus after it almost completely receded.” It also means “a new mutation in the virus, which raises new infections.”

To that, David Weber, the epidemiologist at the University of North Carolina Medical Center, pointed out that the term was used to describe various trends during previous pandemics, including the Spanish flu in 1918 and SARS in 2003.

Weber said that “at that time, the infections reached zero, and then new infections emerged due to a second virus mutation … that is what we mean by a second wave.”
