Social media is mixed blessing in epidemics: WHO

Facebook, Twitter and other social media websites boost public awareness of disease outbreaks but also make it more difficult to separate fact from fiction, world health officials said Thursday.
17 oct 2011--World Health Organization (WHO) director-general Margaret Chan said the Geneva-based UN body scans websites and online forums in different languages for indications of outbreaks across the world.
Any potential threat is analysed by experts and, if necessary, investigated, she told an international conference in Singapore on improving preparedness to fight disease outbreaks.
"I can assure you that with the rise of social media, the background noises for rumours have become much louder and making it so much harder to detect the really important segments," she said.
"But this development also makes it extremely hard for any country to hide a public health threat of international concern."
Chan, who was director of health in Hong Kong when a fatal outbreak of Severe Acute Respiratory Syndrome (SARS) effectively shut down the territory in 2003, did not elaborate.
China was heavily criticised by the international community during SARS for initially covering up the epidemic, which originated in the south of the country.
The flu-like disease eventually killed more than 800 people worldwide, according to the WHO.
WHO assistant director-general Keiji Fukuda said that during the H1N1 swine flu that swept the world in 2009/2010, the Internet was rife with rumours about how to build immunity against the disease.
"One of the rumours which started was that if you increase your salt intake it can help," Fukuda told reporters on the sidelines of the Singapore conference.
The agency had to counter the rumour, also using social media, by telling readers that taking too much salt "will be dangerous to your health", he added.
"The availability of information is better than in the past, and I think this is positive," Fukuda said.
"On the other hand, in social media anybody can say anything so it's also possible that you have a lot of miscommunication mixed in with correct information."

Having a large network of friends and family, a new study suggests, may help surgical patients experience less anxiety and pain before their operations and a quicker recovery afterward.
Researchers studied 605 people scheduled for chest or abdominal operations. They estimated their social connectedness by determining how many close friends and relatives each had, and how often they attended social functions. Using well-validated scales, the patients rated their levels of pain and anxiety before and after their operations.
The one-fifth of patients with the smallest social networks reported almost twice as much postoperative pain intensity as the one-fifth with the largest. Smaller social networks were also associated with longer hospital stays.
The authors, writing in the February issue of The Journal of the American College of Surgeons, say it is not clear from their data whether poor social connectedness is a cause or a result of increased postoperative pain. But when they adjusted for preoperative pain level, the effect of social connectedness on postoperative pain disappeared. This suggests a strong association between social network size and preoperative pain levels, which may be the reason for the easier postoperative recovery.
“The average physician, when he takes a social history, asks about smoking and drugs and not the real social situation of the patient,” said Dr. Daniel B. Hinshaw, the senior author and a professor of surgery at the University of Michigan. “And yet it looks like this is a real marker for problems.”
