This year, the spinal cordytitis virus "appeared" in New York State, London and Israel, the United States, surprised many people. But in the eyes of public health researchers committed to eradicating the disease, this is only a matter of time.

Polygenitis virus can cause acute infectious diseases that seriously endanger children's health, commonly known as pediatric paralysis. According to "Nature", the virus found in the above areas may come from oral spinal ashginitis vaccines used by some countries.

So far, only two cases of paralyzed pivotitis have been reported. Among them, the infection cases in New York have been the first case in the United States in the past ten years. The wastewater samples in the above three areas show that spinal ash virus virus is widely spread.

"No country in the world can avoid the effects of spinal cordylite." Said Zulfiqar Bhutta, a global health researcher at the University of Pakistan Agathan.

Wild spinal ash virus virus is currently only spread in two countries in Afghanistan and Pakistan. In June of this year, there were nine cases of reports in the two countries.

However, the spinal ash virus derived from vaccine is elsewhere, especially Africa and Asia, and can occur cyclically.

These cases come from a widely used oral vaccine that contains weakened vecylinitis virus. This virus can mutate the infection nervous system.

The United States and Britain choose to inactive virus vaccines. Although such vaccines can prevent virus infection from the nervous system, the effect of reducing virus overflow and preventing virus transmission is not as good as oral vaccines.

In fact, the vaccination rate of spinal ash in the United Kingdom, Israel, and the United States is very high, which means that most children can avoid the most serious impact of viruses. However, people who have not vaccinated vaccines are very easy to be infected because this virus is good at discovering individuals who have not vaccinated vaccines.

The World Health Organization (WHO) global eradication spokesperson Oliver Rosenbauer said that in the 1990s, the Dutch -cord iconicitis appeared in a relatively low vaccination rate, although the overall vaccination rate of the country's vaccine exceeded the country 90%, but the epidemic still caused two deaths and 59 people were paralyzed.

In wealthy countries, spinal ash virus monitoring in waters is rarely monitored. For example, Britain is only regular monitoring in London and Glasgow.

After the emergence of paralysis related to spinal cord iconicitis, New York began to monitor wastewater in July.

Therefore, it is unclear how far the virus has spread. However, in London, testing since February found that the virus seems to be concentrated in the north and east of the city, and there have been no paralysis cases related to spinal cordylinitis.

At present, the United States, Israel, and the United Kingdom are strengthening related vaccination work, such as London plans to vaccinate spinal grayitis in all 1 to 9 -year -old children.
