Given the level of infection spread and migration of people on the globe, the epidemic prevention approach to all infection diseases has changed. Any infection, including Ebola, may be brought to any country. It has a long incubation period - 21 days, so it may spread anywhere unnoticed, Popova said.
Popova said accurate forecasting of how the Ebola virus may spread is impossible as it has not been studied sufficiently.“Veritable forecasting is impossible in practical terms today but there are contingencies that have been identified and this helps us fight the spread of the disease in African countries,” she said.
“The world of micro-organisms lives by its own laws and rules and we know far from all of them,” Popova added.
Head of the Russian federal public health control service says there won't be many Ebola cases in Western Europe and the United States, as the level of their health care development is enough for their efforts to be successful to prevent the spread of the disease.
All measures are taken in Russia to prevent the disease from spreading into the country, she said.
The situation is stable in Russia now.
Special measures are taken at airports. Medical personnel and hospitals are in readiness to receive ill people and diagnose the disease, the official added.
There are many factors to make it possible to bring the disease into a country, Popova said. For the present, Russia has no direct flights to West Africa, and there is no intensive migration.
There are foreign students who have arrived from EVD-affected regions, and all measures are taken to monitor their health.
"Today we are absolutely sure and can say it: we have no conditions for spread of the virus inside the country, no natural or any other,” she said, adding: “The measures that are being taken are quite sufficient to prevent an outbreak.”
An outbreak of EVD was reported first in Guinea in February 2014. Later, the virus spread to neighbouring Sierra Leone, Liberia and Nigeria. In late August, it reached Congo and Senegal. EVD cases have been reported in the United States and Europe. Almost 4,000 people have died, and about 8,000 have been infected as of today. The World Health Organization said up to 70% of those infected died of the disease.
