'Around 3 billion animals harmed by Australian bushfires'

Jan 30: The death toll rose to 170 in the new virus outbreak in China on Thursday as foreign evacuees from the worst-hit region begin returning home under close observation and world health officials expressed “great concern” that the disease is starting to spread between people outside of China.

Thursday’s figures cover the previous 24 hours and represent an increase of 38 deaths and 1,737 cases for a total of 7,711. Of the new deaths, 37 were in the epicenter of the outbreak in Hubei province and one in the southwestern province of Sichuan.

The news comes as the 195 Americans evacuated from Wuhan, the Hubei province city of 11 million where the outbreak originated, are undergoing three days of testing and monitoring at a Southern California military base to make sure they do not show signs of the virus.

A group of 210 Japanese evacuees from Wuhan landed Thursday at Tokyo’s Haneda airport on a second government chartered flight, according to the foreign ministry. Reports said nine of those aboard the flight showed signs of cough and fever. Three of the 206 Japanese who returned on Wednesday tested positive for the new coronavirus, Prime Minister Shinzo Abe said during a parliamentary session. Two of them showed no symptoms of the disease.

France, New Zealand, Australia and other countries are also pulling out their citizens or making plans to do so.

The World Health Organization emergencies chief said the few cases of human-to-human spread of the virus outside China — in Japan, Germany, Canada and Vietnam — were of “great concern” and were part of the reason the U.N. health agency’s director-general was reconvening a committee of experts on Thursday to assess whether the outbreak should be declared a global emergency.

The new virus has now infected more people in China than were sickened there during the 2002-2003 SARS outbreak.

Dr. Michael Ryan spoke at a news conference in Geneva on Wednesday after returning from a trip to Beijing to meet with Chinese President Xi Jinping and other senior government leaders. He said China was taking “extraordinary measures in the face of an extraordinary challenge” posed by the outbreak.

To date, about 99% of the cases are in China. Ryan estimated the death rate of the new virus at 2%, but said the figure was very preliminary. With fluctuating numbers of cases and deaths, scientists are only able to produce a rough estimate of the fatality rate and it’s likely many milder cases of the virus are being missed.

In comparison, the SARS virus killed about 10% of people who caught it. The new virus is from the coronavirus family, which includes those that can cause the common cold as well as more serious illnesses such as SARS and MERS.

Scientists say there are many questions to be answered about the new virus, including just how easily it spreads and how severe it is.

In a report published Wednesday, Chinese researchers suggested that person-to-person spread among close contacts occurred as early as mid-December.

“Considerable efforts” will be needed to control the spread if this ratio holds up elsewhere, researchers wrote in the report, published in the New England Journal of Medicine.

More than half of the cases in which symptoms began before Jan. 1 were tied to a seafood market, but only 8% of cases after that have been, researchers found. They reported the average incubation period was five days.

New Delhi, Mar 24: Reports of a person in China dying due to a virus called hantavirus have spread panic at a time when the world is battling the pandemic of novel coronavirus, which began in China.

The novel coronavirus has killed over 16,000 people around the world and the outbreak is yet to be brought under control.

This morning, hantavirus became one of the top trends on Twitter after the Chinese state media tweeted about one person in the country dying due the virus. However, it turns out, hantavirus is not a new virus and has been infecting humans for decades.

Global Times, a state-run English-language newspaper, wrote on Twitter on Tuesday, "A person from Yunnan Province died while on his way back to Shandong Province for work on a chartered bus on Monday. He was tested positive for hantavirus. Other 32 people on bus were tested."

Global Times's hantavirus report on Twitter has been shared over 6,000 times.

On Tuesday, hantavirus was one of the top trends on Twitter.

WHAT IS HANTAVIRUS?

Some people are calling it a new virus but so is not the case. United States's National Center for Biotechnology Information (NCBI) in a journal writes that currently, the hantavirus genus includes more than 21 species.

"Hantaviruses in the Americas are known as 'New World' hantaviruses and may cause hantavirus pulmonary syndrome [HPS]," CDC says. "Other hantaviruses, known as 'Old World' hantaviruses, are found mostly in Europe and Asia and may cause hemorrhagic fever with renal syndrome [HFRS]."

Any man, woman, or child who is around mice or rats that carry harmful hantaviruses can get HPS.

People get HPS when they breath in hantaviruses. This can happen when rodent urine and droppings that contain a hantavirus are stirred up into the air. People can also become infected when they touch mouse or rat urine, droppings, or nesting materials that contain the virus and then touch their eyes, nose, or mouth. They can also get HPS from a mouse or rat bite.

In the US, 10 confirmed cases of hantavirus infection in people who visited Yosemite National Park in California, US, in November 2012, were reported. Similarly, in 2017, CDC assisted health officials in investigating an outbreak of Seoul virus infection that infected 17 people in seven states.

WHAT ARE THE SYMPTOMS OF HANTAVIRUS?

If people get HPS, they will feel sick one to five weeks after they were around mice or rats that carried a hantavirus.

At first people with HPS will have:

Fever
Severe muscle aches
Fatigue

After a few days, they will have a hard time breathing. Sometimes people will have headaches, dizziness, chills, nausea, vomiting, diarrhoea, and stomach pain.

Usually, people do not have a runny nose, sore throat, or a rash.
