[WHO: The New Crown will coexist with humans for a long time] Experts from the World Health Organization warned on the 11th that the term “population immunity” comes from the field of veterinary epidemiology, and should be extra cautious when applied to human infectious diseases such as New Crown Pneumonia Avoid disregarding personal life and suffering.
Michael Ryan, Executive Director of the WHO Health Emergency Program, explained at the regular press conference that day that the term is used in animal husbandry and related decisions are made only from the perspective of “cruel” economics, the status of individual animals Not in the scope of consideration. Extra caution should be exercised when applying the term “group immunity” to human infectious disease-related scenarios, as this may lead to relentless calculations that do not place individual life and suffering into the calculation.
He said that the concept of “group immunization” is mainly used to calculate how many people in the population need to be vaccinated to achieve the corresponding immunization effect.
When about 60% to 70% of members of a group are infected and recovered, the chance of disease outbreak will be greatly reduced, this is the so-called “group immunity” effect.
X-ray exposure X ray hand switch is designed for X-ray equipment, used to control X-ray exposure. The X-ray exposure hand switch can help doctors or operators to stay away from X-ray radiation and operate X-ray equipment safely and conveniently. X-ray exposure hand brakes are widely used in medical X-ray machines, industrial X-ray machines and veterinary X-ray machines.
Our X-ray exposure hand brake is now mainly used for export, and the products are exported to Europe, America, Asia, Africa, Latin America and other countries, and are well received by customers.
Newheek X-ray exposure hand brake adopts a double-key double-open switch design, which is different from other mechanical designs. The mechanical service life reaches 5,000,000 times, and the electronic service life reaches 300,000 times. The internal OMRON micro switch is used for longer life and high sensitivity. .
The first-hand hand brake switch is mainly used on dental X-ray machines, and the appearance is as follows: if you have any requirements, please contact me.
