Tracking infectious disease on TwitterHaitians started dying of cholera just 10 months after the country's devastating earthquake. Researchers say health ministries might have responded more quickly had they seen evidence of the unfolding epidemic in an unlikely place: Twitter. Putting all publicly-available tweets with the word "cholera" and the hashtag "#cholera" on a timeline, researchers at Harvard Medical School were able to show a surge in cholera-related tweets early in the epidemic. The timeline correlates closely with later health-ministry tallies. The researchers used tweets from around the world - 65,728 total with the word "cholera" - that were sent between October 20 and November 3, 2010, including those that came from aid organizations and/or media outlets in Haiti and elsewhere. The goal is to someday harness the immediacy of social media and use it to make better decisions early on about where to deploy public health resources, said Professor John Brownstein of Children's Hospital Boston and co-founder of HealthMap.org, which aggregates global information about infectious diseases. "You don't have a lot of data about what's happening in the population early on - even in the best of situations, even in the U.S., but especially in Haiti. So the idea is what other health information can you draw on to make assessments of the impact of the disease?" said Brownstein. "So in this case, what we were able to show - and this is retrospectively of course - is that utilizing this data that's coming out from these news and social media we can begin to understand the impact. Depending on how transmissible the strain is, it impacts what types of prevention that you do." So far, there's no replacement for the traditional chain-of-command structure of public health that tallies and reports case numbers in an epidemic, but social media could be another tool in the toolbox for decision makers. The next step is figuring out how it could work in real-time, instead of in hindsight. "We found that there was better correlation between the social media and the official case numbers early on," said Rumi Chunara, a research fellow at HealthMap. The tweets didn't coincide uniformly to official health numbers, but there were periods of time when they corresponded best - such as the first incident of the outbreak and then a hurricane which passed by Haiti a few weeks after the cholera epidemic began. Cholera brings about a painful death, as quickly as within two to three hours, because of the amount of fluid and electrolytes that are lost. Symptoms are watery diarrhea, dehydration, nausea and vomiting. The bacterial disease spreads through contaminated water. While it has largely been eradicated in the West, it has been known to come back during war or natural disasters when people are forced to live in crowded places without proper sanitation and clean water. As of mid-December 2011, cholera had killed 7,000 people and infected 520,000 in Haiti, according to the Pan American Health Organization. Medical workers continue to encounter about 200 new cases everyday, said Dr. Jon Andrus, deputy director of PAHO, which is part of the World Health Organization. The best way to prevent cholera is to get clean water and better sanitation. Immediate treatment for the disease is necessary through re-hydration, intravenous fluids, antibiotics and zinc supplements.

Ushahidi-Haiti at Tufts University also tracked twitter data coming out of Haiti shortly after the earthquake. You can view it at http://haiti.ushahidi.com/ It seems like it took a long time for healthmap.org to acquire the data from Ushahidi-Haiti?

While wait loss is not as easy as some would have you to believe. Finding the right combination of what works for you that is the secret. For example what worked for Jane may not work for you. It does take a certain amount of discipline and determination on ones part, however, as previously stated what works for others may not work for you. Not every one has the same metabolism rate.

So is the city health dptmreaent concerned that cholera could be released into the community during sewer overflow events? Can we expect to see cholera showing up in water samples taken from the Gowanus? And is there greater risk to those who boat in places like the Gowanus Canal following sewer overflow events?

When working with clients, we've encountered many instances where they spent 2-3 hours a day on manual work to transfer data from different applications to Magento, POS and vice versa, or from POS to Magento. Noticeably, some situations have even happened for more than 10 years. Moreover, lots of them only came to us to look for an omnichannel POS solution just a few months before their existing POS license expired. They frequently say something like"If only we understood","If we have understood it before", or"We should have paid attention to it". Yes, it is all about"IF". But you can definitely do something about this.

When working with clients, we have encountered many cases in which they spent 2-3 hours every day on manual function to transfer data from different applications to Magento, POS and vice versa, or from POS to Magento. Noticeably, some situations have even happened for more than ten decades. Moreover, a lot of them only came to us to search for an omnichannel POS solution only a few months before their current POS license expired. They often say something like"If only we knew","If we've known it before", or"We should have paid attention to it". Yes, it is all about"IF". But you can definitely do something about this.
