“…the low antibody levels we measured indicate that there is likely to be very little immune protection against this virus…..It is now essential that follow up studies on patients with H7N9 include serological investigations to determine what antibody levels are indicative of clinical protection…..These data will give us a better tool to gauge the size of a second H7N9 outbreak…”-Maciej F. Boni,  Center for Tropical Medicine, Oxford University Clinical Research Unit, Vietnam

Researchers in Vietnam are warning that H7N9 is potentially just as easy to catch as other human flu viruses, and that humans have weak immunity protection against it.

In China, researchers have released data on just who is getting sick and what are the dominant symptoms of H7N9:

100% of infected people had fevers

97% of patients had signs of pneumonia

90% had coughs

76% needed ICU treatment

68% were men

42% were aged 65 years or older

27% died

The researchers also suggested that there could be a genetic reason why some people get sick, and others do not.
