WATCH: Ferguson swears in new police chief

— The city of Ferguson, Missouri, swore in Delrish Moss as its first African-American police chief on Monday.

“Let’s go to work,” Moss told the crowd at his swearing-in ceremony.

A longtime veteran of the Miami Police Department, Moss was selected from 54 applicants to fill the role. He is expected to help rebuild the Ferguson Police Department after racially charged protests broke out over the 2014 shooting death of African-American teenager Michael Brown by a white police officer.

The new face of Ferguson police

The city of Ferguson, Missouri, swore in Delrish Moss as their first African-American police chief. CNN’s Sara Sidner speaks to the new chief about his qualifications.

Moss said Monday the task before the department was to bring “nobility” back to police work.

“If you work hard, if you stay honest and committed, if you maintain respect for the community and do your job well, we will get along just fine,” he said, addressing the police officers in attendance.

Moss may be new to the department, but the problems he faces are not. He’ll be tasked with healing a fractured community in the spotlight since Brown’s shootingof . He’ll have to navigate a mostly white police department in charge of a majority black city.

And he’ll be expected to reform the department under the wary eye of the U.S. Justice Department.

Moss said he is up to the task. It’s a job he’s been training for his entire life, starting with his childhood in Miami and throughout his 32 years with the Miami Police Department.

“I think this is a job based on my previous career that I’ve been training my entire life for,” he told CNN’s Sara Sidner.

Federal oversight

Moss is replacing Tom Jackson, who resigned last year after a Justice Department report cited racial bias in Ferguson’s criminal justice system. The report called for reforms after finding what they called a “pattern and practice” of unconstitutional police conduct in the city.

The federal government sued in February after the Ferguson City Council balked at some terms of a negotiated deal, but the city averted further legal woes in March by unanimously agreeing to accept a Justice Department overhaul of its troubled police force and municipal courts.

In its report last year, the Justice Department highlighted a policing system that uses arrest warrants as generators of income. The report described police practices “shaped by the city’s focus on revenue,” not public needs.

“This emphasis on revenue has compromised the institutional character of Ferguson,” the report said.

African-Americans made up 93% of arrests from 2012 to 2014 but only 67% of the city’s population.

The disproportionate number of arrests of minorities was a result of bias, not crime, the report said.

“These violations were not only egregious, they were routine. They were encouraged by the city in the interest of raising revenue,” U.S. Attorney Loretta Lynch has said. “They were driven, at least in part, by racial bias and they occurred disproportionately against African-American residents of Ferguson.”

Racial distrust

As Ferguson works to recruit more minorities, a big part of the police chief’s role will be reaching out to a community scarred by deep racial distrust.

Brown’s shooting by white police officer Darren Wilson brought national attention to Ferguson’s racial wounds.

But the Justice Department report described a city where officers handcuff minority residents without probable cause, use racial slurs and retaliate against those who question police tactics.

“The residents of Ferguson have suffered the deprivation of their constitutional rights, the rights guaranteed to all Americans, for decades,” Lynch said last year. “They should not be forced to wait any longer.”

Providing a ‘better service’

Moss said he decided to join law enforcement based on two police encounters as a teenager. First, a police officer searched him while he was walking in downtown Miami after dark and called him the N-word. Another time, an officer jumped out of his car and frisked him without notice or warning.

“In both of those experiences nothing was ever done to restore my dignity. I was embarrassed. I was afraid. And I decided then and there that I need to become a police officer. That I needed to provide better service to my community than I was getting,” he told CNN.

“If I wanted change in my neighborhood, I had to be apart of it and so I decided to be a police officer, because I couldn’t trust my neighborhood, my friends, my family to the police officers that I had met.”

American doctor declared free of Ebola finds the virus in his eye months later

— American doctor Ian Crozier was treated for Ebola in Atlanta last year and declared free of the virus in his blood. But he had no way of knowing it still lurked in his eye.

At the time, his eyes were the least of his worries.

“There were lots of things sort of higher on the food chain,” he told CNN’s “Anderson Cooper 360.” “I was struggling to learn to walk again.”

But not long after, mild burning and light sensitivity afflicted his eyes.

Less than two months later, he was back at Emory University Hospital in Atlanta; testing showed the virus was still living in his eye.

Perplexed

His case has left doctors stunned and highlighted the need for eye checkups for Ebola survivors.

Crozier, 44, was hospitalized at Emory University Hospital for more than a month in September after contracting the disease in Sierra Leone, where he worked at a hospital.

At the time, the hospital said he was the sickest of all the four Ebola patients treated there.

Crozier was discharged in October, and about two months later, he developed eye problems and returned to Emory. Doctors stuck a needle in his eye and removed some fluid, which tested positive for the virus.

At the time, Crozier thought the problems were “an immune-related Ebola complication,” but nothing to do with the return of the virus.

“We certainly didn’t think it was related to active and replicating virus in the eye,” Crozier said. “As my sight started to go bad, it became clear that this was a very different animal.”

No risk of spreading the virus

Despite the presence of the virus in the eye, samples from tears and the outer eye membrane tested negative, which means the patient was not at risk of spreading the disease during casual contact, Emory said in a statement Thursday.

It did not name Crozier, but The New York Times did. The New England Journal of Medicine also released a study on the case. Crozier and Dr. Steven Yeh, an associate professor of ophthalmology at Emory University School of Medicine who helped treat him, were both listed as authors of the study.

Though the patient was not at risk of spreading the virus, all health care providers treating survivors, including eye doctors, must follow Ebola safety protocols, said Jay Varkey, assistant professor at Emory University School of Medicine.

Ebola patient for a second time

When the virus was found in Crozier’s eye, the eye started losing its original blue hue. It turned green.

Bewildered, doctors tried different forms of treatment as he relived his Ebola nightmare.

They gave him steroids and an antiviral agent (which required special approval from the Food and Drug Administration, according to the Times.)

His eye gradually returned to normal, but doctors are not sure whether it was as a result of the steroid shot, pill or his body’s immune system.

While Ebola survivors in West Africa have reported eye problems, it’s unclear how prevalent the condition is and how often it happens. Emory advises that Ebola patients should be monitored for the development of eye symptoms like pain, redness, light sensitivity and blurred vision.

Crozier said he hopes his case will bring light to the enormous challenges Ebola survivors face.

“You can imagine an Ebola survivor who’s already been through their own personal hell,” he said. “And as they emerge from that place, to then in a sense face the tragedy of going blind; it’s a story that we must pay attention.”

Epidemic slowly fading

Over the past year, about 25,000 people have fought Ebola infections. More than 10,000 have died, mostly in the West African nations of Liberia, Sierra Leone and Guinea.

While the intensity of the largest Ebola epidemic in history has died down, a few people are still newly infected each week.

At least 18 new cases of Ebola were reported in the week ending May 3, the latest World Health Organization report said. All were in Guinea and Sierra Leone.

But as the number of new cases plummet, many unknowns remain on the aftereffects of the virus.
