An epidemic of the A/H1N1 virus, also known as swine flu, has started in Ukraine, Health Minister Vasyl Kniazevych announced at a press conference on Friday. "Unfortunately, we have to state that an A/H1N1 flu epidemic has in fact started in Ukraine," he said. The Health Ministry is planning to impose quarantine throughout Ukraine, he said responding a question from Interfax-Ukraine. "We are considering the possibility of introducing quarantine not only in the western regions but throughout the country because the virus is spreading extremely fast," he said.
