The H1N1 influenza, which first emerged in Mexico and was declared as a pandemic by the WHO in June, has so far been characterized by the mildness of symptoms in the overwhelming majority of patients, who usually recover even without medical treatment.

According to the WHO, so far there is still no signs of the virus mutating and becoming more fatal despite its fast spreading.

It stressed, however, that the world should keep monitoring the virus and be prepared for any possible changes, especially when winter comes in the northern hemisphere. (Source: Xinhua News)
