According to the report of Xinhua news agency in Latin America: Recently, as some Latin American countries enter the autumn and relax the epidemic prevention restrictions, the number of new coronal infections in many countries has increased. Experts call for improving the vaccination coverage. According to the data of the Brazilian Ministry of health, in the past week, there were 166777 newly confirmed cases in Brazil, the highest in the past two months. As of the 29th, Brazil has reported more than 30.95 million confirmed cases and more than 660000 deaths. Emerson Luce, a Brazilian infectious disease expert, said that the number of new crown cases will increase as the weather turns cooler. The increase in the number of new crown cases is also related to the characteristics of the Omicron mutant. The influencing factors also include the relaxation of epidemic prevention measures and people's resumption of offline activities and parties. He said that the health authorities should analyze the increase in cases in some areas and expand vaccine coverage. On the 27th, the Brazilian Ministry of health opened the new crown vaccine booster injection for adolescents aged 12 to 17. The Brazilian Health Supervision Bureau authorized Pfizer and Kexing vaccine as the booster injection for this age group to be vaccinated four months after the second dose of vaccine. In addition, the Ministry of health also recommended that people over 60 years old and people with low immune function receive the second dose of booster four months after the first dose of booster.
