Exponential expansion of an infectious disease occurs when the rate of growth is proportional to the number of people currently infected. The mathematical formula for exponential growth is: [x_t = x_0(1+r)^t] In the case of Ebola, xt represents the total number of people infected, xâ‚’ represents the number of index cases at the starting point, r represents the rate of disease transmission (believed to be about 2 for Ebola, i.e.: each Ebola victim transmits the disease on average to 2 other people), and t (as an exponent) represents the time interval used for measurement (months). The formula reduces to xt...

The information provided below could save your life in the event of an all-out pandemic. It will also show you how the world’s governments and health officials aren’t reacting appropriately to this crisis… and why you shouldn’t depend on them to save you. “You can start almost anywhere on any day since the outbreak began and then see that the numbers double every three weeks. That means that by the end of December, we should be looking at 300,000-400,000 cases, again with the number doubling within three weeks and then doubling again, etc. Even the Centers for Disease Control has...

The deadly Ebola virus could spread across the world infecting people from the U.S. to China within three weeks, scientists have warned. There is a 50 per cent chance a traveller carrying the disease could touch down in the UK by October 24, a team of U.S. researchers have predicted. Using Ebola spread patterns and airline traffic data they have calculated the odds of the virus spreading across the world. They estimate there is a 75 per cent chance Ebola will reach French shores by October 24. And Belgium has a 40 per cent chance of seeing the disease arrive...

Hi folks, just ran some math with Ebola numbers. According to WHO, there were 3053 cases back in 25 Aug and 8033 cases in 5 October. http://www.who.int/csr/disease/ebola/situation-reports/en/ This gives an average daily increase of 3.9806%. At that rate, given a world population of 7.125 billion, EVERYONE will be infected in 349 days. Have a nice day!

When the experts describe the Ebola disaster, they do so with numbers. The statistics include not just the obvious ones such as caseloads, deaths and the rate of infection, but also the ones that describe the speed of the global response. Right now, the math still favors the virus. Global health officials are looking closely at the “reproduction number,” which estimates how many people, on average, will catch the virus from each person stricken with Ebola. The epidemic will begin to decline when that number falls below one. A recent analysis estimated the number at 1.5 to two. The number...
