One person has already died from A/H1N1 in Shenzhen, as the virus begins to spread once again in south China. Health officials are advising people in Shenzhen to get vaccinated ASAP (and probably also advisable for those in other PRD cities):
The 625 community health centers in Shenzhen have the A/H1N1 vaccine, the domestically made vaccine is available for 40 yuan per administration. the imported vaccine is priced at 80 yuan. the vaccine is a precaution to the three types of influenza namely A/H1N1, H3N2 and influenza B. Since Shenzhen is now entering the peak influenza season the city will be seeing more cases of the A/H1N1 virus because of people returning to Shenzhen coming from the Spring Festival break.
Of course, do the usual to try and stay healthy, such as wash your hands regularly and get lots of fresh air.
