What we know and don’t know about the coronavirus

The spread of a new coronavirus in mainland China and to 27 countries and regions beyond is alarming health experts. Here is what we know – and do not know – about the virus:

HOW DANGEROUS IS THE VIRUS?

The coronavirus family of viruses includes the common cold and more serious diseases such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS).

Many of those with the new virus who have died had pre-existing medical conditions or were elderly, those with weakened immune systems.

Coronavirus infections have a wide range of symptoms, including fever, cough and breathing difficulties.

Statistics from China indicate that about 2% of people infected with the new virus have died, suggesting it may be deadlier than seasonal flu but less deadly than SARS, which killed about 10% of infected individuals. The MERS outbreak in 2012 had a fatality rate of about 35%.

Scientists have labeled the new virus 2019-nCoV.

HOW IS IT TRANSMITTED AND HOW CAN IT BE PREVENTED?

The virus can be transmitted via droplets when an infected person breathes out, coughs or sneezes, and can also spread via contaminated surfaces such as door handles.

Experts have said it is more easily transmitted than the SARS virus. The incubation period is up to 14 days. People may be able to infect others before symptoms appear.

The World Health Organization (WHO) recommends that people frequently wash hands, cover mouth and nose when sneezing or coughing, and avoid close contact with those who are sick.

DO FACE MASKS HELP?

“We recommend the use of masks for people who have symptoms … because the virus transmits through droplets,” says medical expert Sylvie Briand.

But they do not guarantee protection against infection.

 

“For people who don’t have symptoms, the mask in fact is not useful,” Briand says.

The American Centers for Disease Control’s advice is that face masks are not required for the general public.

IS THERE ANY TREATMENT?

There is no vaccine.

Chinese scientists were able to identify the genetic sequence of the new coronavirus and shared it publicly. Scientists in Australia have developed a lab-grown version of the virus, a step toward creating a vaccine.

Drugmakers around the globe expect to begin testing experimental vaccines on humans in about three months.

WHERE HAS IT SPREAD?

About 99% of the more than 20,000 cases have been reported in mainland China. Nearly 230 cases have been reported in about 27 other countries and regions, a Reuters tally based on official statements shows.

At least 490 people have died in China, most in and around the city of Wuhan, where the virus emerged late last year. One person has died in Hong Kong and one in the Philippines, both following visits to Wuhan.

Singapore confirmed four more coronavirus cases on Feb. 5 taking its tally to 28. Thailand has 25 cases.

It took the new coronavirus 48 days to infect the first1,000 people. It took SARS 130 days to infect 1,000 people. It took MERS 2.5 years to infect 1,000 people.

WHAT ARE AUTHORITIES DOING?

The Chinese government has virtually locked down the central province of Hubei, home to 60 million people, and its capital Wuhan.

China is facing mounting isolation as airlines suspend flights to its cities.

The United States and Australia have banned entry to foreign nationals who have recently traveled to China.

Many countries have evacuated their citizens from Hubei and are putting them in quarantine or isolation upon return.

The WHO has not recommended travel or trade curbs with China.

WHERE DID THE VIRUS COME FROM?

It is believed to have originated in a food market in Wuhan that was illegally selling wildlife. Health experts think it may have originated in bats and then passed to humans, possibly via another species.

Hana raises concerns over Afghan women and children amid Iran’s expulsion policy

It said the risks are particularly serious for children born in Iran or those who have spent much of their lives there.

Published

The Hana Human Rights Organization has raised serious concerns over the situation of Afghan women and children in Iran, saying the country’s plan to regulate and expel undocumented Afghan nationals remains in effect.

According to Hana, Iran’s Ministry of Interior has confirmed that the “Plan for the Regulation and Expulsion of Unauthorized Afghan Nationals” has not been suspended.

The organization said the policy is continuing amid the consequences of armed conflict and an increasingly securitized environment in Iran, which it said has heightened the vulnerability of Afghan migrants and asylum seekers.

Hana said it has previously documented cases involving the arrest and mistreatment of Afghan nationals, deportations, family separation and difficulties obtaining civil documentation and accessing essential services.

The organization warned that continued implementation of the expulsion policy could worsen these problems.

Hana expressed particular concern for Afghan children under 18, stressing that children’s rights are independent of their parents’ migration status.

It said irregular residence should not, by itself, justify a child’s detention, separation from family or removal without an individualized assessment. Any decision affecting a child, it added, should prioritize the child’s best interests, preserve family unity and provide additional safeguards for unaccompanied and separated children.

The organization warned that large-scale expulsions without clear procedures to identify and protect children at risk could result in family separation, disruption to education, lack of legal protection, difficulties establishing legal identity, exploitation and return to unsafe conditions.

It said the risks are particularly serious for children born in Iran or those who have spent much of their lives there.

Hana also highlighted gender-specific risks facing Afghan women and girls. It warned that deportation to Afghanistan without assessing risks linked to gender, previous political or social activities, family circumstances and access to support networks could expose them to serious human rights violations.

The organization said being classified as an “unauthorized foreign national” should not replace an individual assessment of a person’s protection needs and the risks they may face upon return.

Hana stressed that while states have the authority to regulate the entry and residence of foreign nationals, migration enforcement must comply with international human rights principles, including non-refoulement, the prohibition of collective expulsion, access to individualized procedures and respect for family unity.

It called for heightened protection for women and children, warning that continuing the expulsion plan without effective legal and protection safeguards could lead to further human rights violations against Afghan migrants and asylum seekers in Iran.

Water dispute in Baghlan leaves four dead

Published

Security officials in Afghanistan’s Baghlan province say an armed clash between members of two families over a personal dispute and access to water for agriculture in Tala wa Barfak district has left four people dead and one injured.

Ismail Ayubi, police chief of Tala wa Barfak district, said the incident took place in the Dewalk area of Barfak, a remote part of the district.

He said the main cause of the clash was a dispute between the two families over the use of agricultural water.

Baghlan police said that, due to the lack of mobile network coverage in the area, a local resident traveled to an area with network access to report the incident to security forces.

Following the report, security forces took the necessary steps to respond to the incident. Officials said those involved in the clash fled the area after the incident, and no one has so far been arrested.

The district police chief said efforts are ongoing to identify and arrest those responsible. Security forces are also working to maintain public safety and prevent further insecurity in the district.

An investigation into the circumstances of the clash and the identification of those involved is ongoing.

Afghan children return from malnutrition treatment to food-insecure families

Published

Children recovering from malnutrition in Afghanistan often return to households that lack the resources to provide the nutritious food they need to fully recover and grow, Action Against Hunger has warned.

The organization said recurrent drought, poverty, food insecurity and limited household incomes are making it difficult for families to prevent children from falling back into malnutrition after completing treatment.

However, repeated drought and other climate-related shocks have reduced harvests and household income, leaving families struggling to provide adequate nutrition for their children.

Action Against Hunger said the situation highlights the need to go beyond treating malnutrition and address the underlying causes of hunger and poverty.

The warning comes as malnutrition cases continue to rise across Afghanistan. In June 2026, the Therapeutic Feeding Unit in Kabul recorded 142 new admissions, a 149 percent increase compared with the same period in 2025.

Similar increases have been reported in other provinces where Action Against Hunger operates. In Lashkar Gah, Helmand province, the organization expanded the capacity of its therapeutic feeding unit from 45 beds to 72 and then to 118 within a matter of weeks due to the sharp rise in cases.

Action Against Hunger said climate-related shocks, including severe winter conditions, drought and water shortages, have further weakened food security across the country. Water shortages have damaged agricultural production in rural areas, forcing some families to leave their homes in search of livelihoods and basic necessities.

The organization stressed that sustained investment in both emergency nutrition services and longer-term livelihood programmes is needed to help families break the cycle of poverty and recurrent malnutrition.

Cobi Rietveld, Afghanistan Country Director at Action Against Hunger, said addressing the root causes of hunger is essential for achieving lasting progress against malnutrition.

“When families have the means to earn a living and provide for their children, the benefits extend far beyond nutrition,” Rietveld said, adding that livelihood support can help families meet their needs with dignity, protect children’s futures and build resilience against future crises.
