The new global outbreak due to the Delta transformation shows that the only Covid-19 escape is a global vaccination to force NCOV to retreate.

In May, the globe witnessed the prospective atmosphere, when NCOV cases fell sharply across the United States and many regions in Europe and the Middle East, in the context of increased vaccination rate.

It seems to see the end of the tunnel end, the countries race to loosen limited measures and open businesses.

However, at least in the US, short joy is not tay gang.

Even in the scientific community, you will also get different answers, Rachael Piltch-Loeb, researchers and members of the Emergency School of Medical Research and Evaluation

Pandemic by definition is a global crisis.

It will not disappear until the virus is controlled or limited globally, Piltch-Loeb said, adding that this means that the Extensive Pandemic Declaration may be a far away target, depending on many conditions

When the spread of a global disease is controlled in a local area, it is no longer a pandemic that will be a disease, according to WHO.

At that stage, NCOV will become a virus that does not have a serious influence because people have built immunity, according to Saad Omer, epidemiologist and director of Yale Global Health Institute.

Only two diseases that have affected people and animals have been wiped out of smallpox and cattle cholera (Rinderpest).

Joshua Epstein, professor of epidemiology at New York University Public Health School, said that erasing viruses rarely in this level should be removed from the dictionary of pathology.

Most pandemic in the past still to this day.

As the 1918 flu pandemic, NCOV virus will continue to transform and the human immune system will eventually adapt themselves without vaccination.

Experts believe that the optimal way is to find a way to slow the spread of translation and control its consequences.

For other diseases such as influenza, vaccines also make a difference.

WHO director Tedros Adhanom Ghebreyesus repeated the vaccination target for at least 10% of the population of all countries in September, reaching 40% of the global population of vaccination before the end of this year and 70% in mid-next year.

However, the supply of limited vaccines, especially in low-income water groups, is hindering this goal.

In this context, NCOV has many opportunities to spread and mutations, making many new strains dangerous at risk of appearing.

Michael Osterholm, director of the Policy Center and Infectious Planning Center at the University of Minnesota, says the complexity of the war with a rapid mutation virus that sometimes has two steps and back a step forward.

In addition, many scientists and historians believe that humans may consider the pandemic to end before any management agency claims.

This happened in the past.

However, many social warning professionals can face tragic consequences if everyone seeks to consider the pandemic that has ended before the science gender actually spoke up.
