premise: Deng Haihua, Ministry of Health spokesperson, expects the disease to reach its height between May and July. Yang Weizhong Deputy Director for the Chinese Center for Disease Control and Prevention said researchers are increasing research efforts to find a vaccine for EV71. Families are being instructed to embark on week-long disinfections with free medical supplies from local health authorities.
hypothesis: There is no treatment for EV71.
reason: Just because there is no vaccine does not mean there is no alternative treatment. For example, perhaps it's like influenza, where general rest, IV or experimental treatments are available.
