The Ebola virus can live on surfaces in hospitals for nearly two weeks, a new study suggests.

Researchers tested how long the Ebola virus could survive on plastic, stainless steel and Tyvek, a material used in Ebola suits. The researchers also simulated different environmental conditions, including a climate-controlled hospital at 70 degrees Fahrenheit (21 degrees Celsius) and 40 percent humidity, and the typical environment of West Africa, at 80 F (27 C) and 80 percent humidity.

In general, the virus survived on surfaces for a longer time when in the climate-controlled conditions than in the West African environment, the study found. Under hospital-like conditions, the virus lived for 11 days on Tyvek, eight days on plastic and four days on stainless steel. The longest the virus was able to survive in the tropical conditions of the West African environment was three days, on Tyvek.

Now the threat from Ebola seems to be receding, rich countries must not revert to their former myopia. Listening to other countries’ needs and investing in women and children would be a start

Amnesia has set in across the world as the fear and global attention given to Ebolarecedes. But this is not a new phenomenon. With Sars, avian flu, swine flu and Mers, there were repeated calls to fix the global health system to avoid previous mistakes. We cannot continue to be surprised when a health crisis emerges and we need to start to take a long-term, inclusive perspective to ensure health security across the world. Myopia was a key factor in the failure to respond to Ebola in a rapid and effective way.

There are three immediate steps that should be taken:

...Guinea is where some of the last embers of West Africa's Ebola epidemic are smoldering. It had only 21 new Ebola cases in the past week, 16 of them in the city of Forécariah, a 3-hour drive from the capital. Guards at many official buildings still routinely point the Thermoflash, a contact less, revolver-shaped thermometer, at visitors' temples, and vats full of bleach are still omnipresent.

 But Ebola rarely makes headlines anymore, and antigovernment protests that paralyzed Conakry last week were about upcoming elections, not the virus.

Still, Guinea's Ebola czar, Sakoba Keita, notes that there have been lulls before, the last one in January, that were invariably followed by flare-ups.

...Guinea's stubborn epidemic means that it may soon be the last place where researchers can do real-world tests of Ebola treatments and vaccines.

(Contains new information on the origin of the Ebola epidemic.)

Scientists are using blood samples collected throughout the Ebola outbreak to map the virus’s spread from country to country by tracking tiny mutations in its gene sequences.

The picture is not yet complete, but intriguing discoveries have been made. Virus mutations first detected in Sierra Leone last spring were found later in Liberia and Mali, and scientists are examining whether this resulted from the chance movements of people across borders....
