But flash is still ongoing, new cases are recorded less frequently, in May than in April, the Centers for Disease Control and Prevention said.

Bird Flu Cases Declining, Health Officials Say

As of May 8, was 131 total number of cases of H7N9 avian influenza, and 32 of these patients died.

In the first week of April, 21 new cases of the disease were registered in total, with a few cases reported every day this week. In contrast to this, health officials were notified only four additional cases between May 2 and May 7. The world Health Organization is now releasing updates about new H7N9 cases only once a week, but not daily.

The reason for the fall is not clear. This may be due, mainly, to the efforts to reduce exposure to the virus throughclosing live bird markets, the CDC said.

But it could also be the result of the change of the seasons. The same as human flu viruses, bird flu viruses follow seasonal patterns, as well as – for example, a virus of ” bird flu ” H5N1 is known to be more active in the winter than in the summer. The structure of H7N9 remains to be seen, but it is quite possible that cases can take in the cold months, the CDC said.

Right now, there are no reports of sustained human-to-human transmission of the virus.

No cases of H7N9 seen in the United States, and at the present time, the risk for the people living in the United States remains low, the CDC said. Even if in the case of H7N9 reported in the United States, it is not necessarily enhance the overall level of risk. (The risk will increase, if the transmission of the sample change – for example, if she begins to spread between people, the CDC said.) If people in the United States it was established, H7N9, he or she would be isolated, and people, that the patient came in contact with will be tested for the disease.

CDC is in the process of development H7N9 influenza vaccine in the event, if this is necessary. As a rule, it takes from six months to produce large quantities of vaccine from a flu, but health officials have yet to decide whether to serial production H7N9 vaccine.
