Kekula reduced the rate to 25 percent. Four of her family members were infected with the virus. Her father, Moses, her mother, Victoria, her sister, Vivian and her 14-year-old cousin, Alfred Winnie. Sadly, Kekula's cousin _ the virus. It's also impressive to note that while Kekula was treating her family members she managed to avoid Ebola entirely. On July 27, Kekula's father, Moses, went to a hospital in Kanata, after his blood pressure rose sharply. The only reason the hospital had a bed to offer him was because someone had just died.

Once nurses started dying of Ebola, the hospital shut down and Moses had to leave. Kekula drove 90 minutes to Monrovia, the capital of Liberia, to seek treatment. Three hospitals turned them away because there is no spare bed for patients at all. Kekula made the drive back to Kanata to another hospital.

Example Input: Article: Speeding off in a stolen car, the thief thinks he has got a great catch.But he is in for an unwelcome surprise.The car is fitted with a remote immobilizer, and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again. The idea goes like this.A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS satellite positioning receiver.If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted. In the UK, a set of technical fixes is already making life harder for car thieves." ," says Martyn Randall, a security expert.He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools.But only if the car is more than 10 years old. Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code sent out by the ignition key.In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys.And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen.The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit.
