The patients are in District 2 and 12. Both showed commonly seen symptoms of the mosquito-borne virus, including high fever and joint and muscle pain. Both are stable and being monitored by doctors at their home.

Vietnam has been on high alert since the first cases of the virus were confirmed in the country in April. Among the seven cases recorded so far, HCMC has four, following by Binh Duong, Khanh Hoa and Phu Yen with one case each.
Health officials have been working to prevent a potential outbreak, by testing a large number of blood samples, setting up quarantine zones and organizing mosquito control campaigns.
