The World Health Organization said on the 2nd that European large-scale enterohemorrhagic E. coli (EHEC) epidemics were triggered by a "highly contagious and toxic new virus" that was "unprecedented". Germany’s Reinhard Booger, director of the Robert Koch Institute, a public health agency responsible for responding to the outbreak of EHEC, said on the 2nd that the outbreak may last for months.
Viruses are two kinds
Variants of E.coli
On the same day, WHO said that preliminary gene sequencing indicates that the new virus is a variant of two different E. coli strains and contains a lethal gene.
This is a unique virus, says Hilde Crouse, WHO food safety expert. Compared with many E. coli viruses naturally carried in the human body, the new virus has “a variety of characteristics that make it more lethal. More easily produce toxins." It is difficult to explain this new virus source at this stage.
She said that some of the viruses that humans and animals carry together are prone to gene swaps. For example, humans sometimes become infected with animal viruses. "The new type of E. coli should be considered animal-like. Many animals carry many types of toxin E. coli."
Researchers had previously questioned that the outbreak may have originated from growing vegetables with contaminated fertilizer.
Compared to the previous cases where the E. coli outbreak was mainly for the elderly and children, the patient was mainly adults, especially women. Cruze said that the new virus may have "some characteristics" that make it more dangerous for adults.
The culprit is difficult to determine
The European Center for Disease Prevention and Control issued a statement on the 2nd, according to the analysis of 10 cases of death and 499 cases of hemolytic uremic syndrome. "Experimental results showed that Shiga toxin-producing E. coli serogroup 0104:H4 is the pathogen."
However, the statement also stated that 7 cases and 2 cases of "unrecognized type" were found in Germany and Denmark respectively. The contaminated food "appears to be the most likely medium of transmission for this epidemic. There is no evidence at this stage that raw milk or meat is related to this epidemic", but the specific circumstances are still under investigation.
Increased outbreak
As of June 2, the outbreak spread in at least nine countries in Europe, 18 confirmed deaths, and more than 2,000 were infected, including 470 people with complications of renal failure.
Germany is the "stricken area" of the epidemic. The European Center for Disease Prevention and Control said: “Almost all patients have come from or recently traveled to northern Germany. Within the European Union, Sweden, the United Kingdom, the Netherlands, Denmark and Spain have reported cases of hemolytic uremic syndrome associated with this outbreak. â€
Man eats sandwich death
Do not rule out E. coli deadly
According to the French “Expressâ€, a 47-year-old man in France suffered severe abdominal pain, nausea, and vomiting after eating a sandwich containing lettuce and tomatoes, and died within 3 hours later in his apartment. The cause of death has not yet been confirmed. A prosecutor said, "There is no evidence that his death is related to the deadly bacteria that raged in Germany, but it cannot be ruled out."

UAE: Stop importing cucumbers from 4 countries
The UAE announced on the 2nd that it would ban the import of cucumbers from four European countries.
The UAE’s “National†reported on the same day that a few hours after the Ministry of Environment and Water Resources announced a temporary import ban, some supermarkets in Abu Dhabi have “putted cucumbers imported from Germany, Spain, Denmark, and the Netherlands to start a second round of E. coli. Pollution Test."
At the same time, other vegetables from these European countries are still allowed into the UAE, provided that the importer can provide a health certificate that these foods have not been contaminated by E. coli.
Russia: Bans imports of vegetables from the EU
The Director of Consumer Protection and Public Welfare Supervision of the Russian Federation and the General Guardian of Russia, Gennady Onisenko, revealed on the 2nd that the agency issued a temporary ban prohibiting the import of fresh vegetables from all EU countries.
Onishchenko said: "Because the epidemic was not controlled within a month, the source of infection and the route of transmission could not be determined, and the recent situation has deteriorated drastically. We have no alternative but to take this unwelcome measure and implement a temporary ban."
Onishchenko said that the ban will continue until “when the epidemic is confirmed and begins to be effectively controlled.â€
China: Cucumbers not imported from the EU
According to the news published by the website of the State Administration of Quality Supervision, Inspection and Quarantine, the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) has paid great attention to the European Union’s E. coli pollution incidents of cucumbers and has requested all entry-exit inspection and quarantine agencies throughout the country to strengthen the monitoring of EHEC contamination in vegetables exported from Europe to China. To ensure the quality and safety of imported vegetables. The General Administration of Quality Supervision, Inspection and Quarantine stated that it is understood that at present China does not import fresh vegetables such as cucumbers, tomatoes, eggplants and lettuce from EU member states.
