The second 'Dallas' nurse to contract Ebola is being released from Emory University Hospital in Atlanta on Tuesday.

Amber Vinson, 29, cared for Thomas Duncan, the Liberian man who died of Ebola at Texas Health Presbyterian Hospital earlier this month. She was one of 50 to 70 health care workers who tended to Duncan. The other nurse who contracted Ebola was released from hospital four days ago.

U.N. Secretary-General Ban Ki-moon said the transmission of the virus continues to outpace the international community's response. He appealed to the African Union's 54 member states not to impose Ebola-related restrictions or close their borders. The African Union states have pledged to send more than 2,000 health care workers to West Africa, but the president of the World Bank says at least 5,000 more health workers are needed to fight the epidemic.

In an interview with RT.com, Laurent Duvillier, regional communications specialist for UNICEF, said there are three major concerns when treating Ebola in Liberia. One is the fear of contracting Ebola which has caused many mothers to initially stop coming to clinics for vaccinations for other diseases like measles, polio and pneumonia. Another problem is creating a culture of hand washing, and UNICEF is training teachers about promoting hand washing, which helps cut down transmission rates of Ebola.

The other major concern is how much clean water is needed to treat an Ebola patient. On average, an Ebola patient needs 150 liters of safe water every day. The water is used for drinking, but also to wash clothes, hands, and disinfect bodies and outfits used by the medical doctors and nurses.

"So the quantity of water that we need every day for each patient is very, very high in a country where in normal times every citizen has access to 15 liters of safe water per day. That means we need to ensure 10 times the quantity of safe water is accessible for this Ebola treatment unit ... it is a big, big challenge," said Duvillier.

Duvillier says they are digging blow holes, and working with water companies to ensure there will be no interruption in supply.

Swissmedic, the Swiss agency that regulates new drugs, has approved the applications for a clinical trial with an experimental Ebola vaccine at the Lausanne University Hospital, reported The Associated Press. The trial will be administered to 120 volunteer participants with support from the World Health Organization, who will then be sent as medical staff to fight Ebola in Guinea, Liberia and Sierra Leone. The trial is the continuation of a series that began in the United States, Britain and Mali, using a vaccine based on a genetically modified chimpanzee adenovirus.

Illinois Gov. Pat Quinn joined the governors of New York and New Jersey and declared a mandatory quarantine which will force returning health care workers who have had contact with Ebola victims to stay at home.

"In the interest of the public and public health, it will be mandatory," said Quinn. "We have to be on our toes."

The governor of Maryland has made a similar announcement as well as governor of Minnesota.

A nurse quarantined under the new rules on Friday when she arrived at Newark International Airport after working with Ebola patients in West Africa has been released. Kaci Hickox is being taken to Maine where she lives by private vehicle. Maine's protocols require she be quarantined in her home for 21 days.

A New York boy, 5, who recently traveled to Guinea and had a fever does not have Ebola. He returned from Guinea with his family on Saturday and felt sick on Sunday. Emergency responders in protective gear took him and his mother to Bellevue Hospital in Manhattan. He developed a fever but tested negative for Ebola. Officials are doing further tests and he will stay at the hospital until those results return.

Dr. Craig Spencer, also at Bellevue, is in serious but stable condition after testing positive for the Ebola virus. He worked in Guinea with Doctors Without Borders, and had been treating patients with the virus before returning to New York.
