Fifty-six journalists were killed in 2019 and most of them died outside conflict zones, a United Nations spokesperson said.

The number dropped by nearly half from the year 2018, but perpetrators enjoyed almost total impunity, Xinhua news agency quoted Stephane Dujarric, spokesperson for UN Secretary-General Antonio Guterres, as saying on Monday citing Unesco figures.

The figure was published in the 'Unesco Observatory of Killed Journalists' on Monday.

In total, Unesco recorded 894 journalist killings in the decade from 2010 to 2019, an average of almost 90 per year. The number in 2019 was 99.

Journalists were murdered in all regions of the world, with Latin America and the Caribbean recording 22 killings, the highest number, followed by 15 in Asia-Pacific, and 10 in Arab States.

"The figures show that journalists not only suffer extreme risks when covering violent conflict, but that they are also targeted when reporting on local politics, corruption and crime - often in their hometowns," the Unesco said.

Almost two thirds (61 per cent) of the cases in 2019 occurred in countries not experiencing armed conflict, a notable spike in a wider trend in recent years, and a reversal of the situation of 2014, when this figure was one third.

More than 90 per cent of cases recorded in 2019 concerned local journalists, consistent with previous years, it added.

In response to these figures, Audrey Azoulay, the Director-General of Unesco, said: "Unesco remains deeply troubled by the hostility and violence directed at all too many journalists around the world.

"As long as this situation lasts, it will undermine democratic debate."

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.
