He says enhanced prophylactic measures have been taken, since there are more and more cases reported in Romania, Russia and now Ukraine. “The population is warned about the risks. The medical centers are obliged to stay cautious and to adjust their actions according to the situation,” Moldovanu said. The Health Division warns the people to avoid crowded places and contacts with people suspected of being sick. It recommends to wash one's hands as often as possible and to observe the healthy life style. “In case one notices flu symptoms, one shall call a doctor urgently. Drink much water, cover your nose and mouth, inform your family,” the functionary informs. There is no vaccine against the A (H1N1) flu. According to French media, scores of drug manufacturers are trying to develop the antidote. The results are expected in August.
