The epidemic defense line has been broken through again, and the new crown virus "undead" is a difficult battle
In the protracted battle against the coronavirus, it seems that another ominous signal has been struck. A mysterious mutant "FLiRT" family has begun to spread around the world, and the number one killer strain, KP.2, is even more difficult to prevent. What kind of terrifying strength does this "undead" have? And how will humanity respond to their challenges? Let's find out.

The Mystery of Origins: Finds in the Sewers
The discovery of this family stems from a seemingly mundane scene – the American sewer system. Yes, you heard it right, it was in those dark, damp, filthy drains that scientists caught a whole new variant of the coronavirus.
At first, it was seen as an interesting little discovery, but as we delved deeper, the veil of this family gradually became known. They are collectively referred to as the "FLiRT" family and are derived from the mutated location of these variants on the spike protein. According to genetic analysis, they all descend from a common ancestor, the JN.1 variant.
In this family, KP.2 is undoubtedly the most striking member. Starting in the United States, this variant quickly became dominant in several countries, spreading at an alarming rate. According to the CDC's surveillance data, as of May 11, KP.2 accounted for 28.2 percent of the population in the United States, up from less than 6 percent just a month ago.
"Hell Demon King" or "Side Clown"?
In the face of the sudden rise of KP.2, many authorities around the world have sounded the alarm. The World Health Organization (WHO) has listed it as a priority surveillance variant in early May, and is closely monitoring its development.
Professor Lawrence Young, a virologist at the University of Warwick in the UK, admits that while it is too early to tell whether KP.2 is more dangerous, they are concerned that the sublineage could trigger a new wave of infections in the summer.
Isaac Bogoch, a well-known Canadian infectious disease expert, also expressed concern about KP.2's ability to escape immunity. He believes that the latest mutation may have made the variant better at evading recognition by the body's immune system, leading to a surge in cases.
However, some experts believe that KP.2 and its family do not pose a threat enough to cause alarm. Although they appear to be more contagious, symptoms and severity are comparable to previous variants, and existing vaccines still provide some protection against them.
William Schaffner, a professor at Vanderbilt University School of Medicine, holds this view. He admitted that there is no essential difference between the new mutations, they all evolved to improve infectivity, and they have not shown greater lethality for the time being. "We are in the genomic era, and there are already several subvariants that are dominant. They are highly contagious, but they do not appear to produce more serious diseases. "
Defensive Battle: Humanity's resourcefulness prepares for war
Whatever the fate of KP.2 and his family, humanity must be fully prepared for a possible new wave of the pandemic.
In terms of vaccines, many pharmaceutical companies around the world have begun to develop and upgrade vaccines to meet the challenges of these new variants. The good news is that even with the protection of current vaccines, the risk of severe disease remains manageable.
In addition, oral therapeutics have also become an important strategic weapon against new variants. A number of new viral drugs have been or will soon be marketed, which are expected to provide new treatment options.
At the level of public health policies, countries are also continuing to improve their surveillance systems and adjust their prevention and control strategies. For example, the US Centers for Disease Control and Prevention has included the KP family in its priority tracking target to better assess their impact on public health. Some areas have also reinstated protective measures such as mask mandates and testing.
However, the greatest supply point in this battle is still the prudence and honesty of humanity itself. As experts say, everyone should be up to date on vaccination, especially those at high risk. As ordinary people, we have a responsibility to remain vigilant at all times, strictly follow all protective measures, report symptoms honestly and transparently, and work together to help stop the virus.
Danger and opportunity: witness greatness in the ordinary
Perhaps, this difficult battle between the virus and humanity will be a never-ending "marathon battle". But it also teaches us the great resilience of humanity in times of crisis.
In the face of the uncertainty of virus mutations, scientists have captured the traces of emerging variants such as KP.2 for the first time with amazing insight and perseverance, and quickly attracted the attention of relevant parties around the world.
In terms of vaccine research and development and drug development, pharmaceutical companies have worked tirelessly to develop and optimize products with extraordinary courage and determination, so as to hold up a protective umbrella for mankind.
At the grassroots level, hundreds of millions of ordinary people are fighting the virus in an ordinary, but also the most extraordinary way. Each of them became a warrior in this battle.
Like every disaster that mankind has experienced in history, we will eventually overcome the difficulties that lie ahead. In the smoke of the battle against the new coronavirus, it will be reborn and create a more brilliant future.
