New Delhi, Mar 21: Prolonged symptoms of Covid-19 may be associated with difficulty recognising faces, a little-known condition called face blindness, and navigational problems, according to a study.

Previous studies have shown that Covid-19 can cause a range of neurological problems, including the loss of smell and taste, and impairments in attention, memory, speech, and language, known as "brain fog".

The latest research, published in the journal Cortex, is the first to report prosopagnosia, or face blindness, following symptoms consistent with Covid-19.

The condition that can make people fail to recognise familiar faces, has been estimated to affect between 2 and 2.5 per cent of people in the world.

The researchers assessed the case of Annie, a 28-year-old customer service representative and part-time portrait artist in the US, who was diagnosed with Covid-19 in March 2020 and suffered a symptom relapse two months later.

"When I first met Annie, she told me that she was unable to recognise the faces of her family," said Marie-Luise Kieseler, a graduate student at Dartmouth College in the US, adding Annie now relies on voices to recognise people.

Annie also experienced navigational deficits after having Covid-19. She has had difficulty remembering where particular sections in her grocery store are and relies on Google maps and its pin function to remember where she parks her car.

“The combination of prosopagnosia and navigational deficits that Annie had is something that caught our attention because the two deficits often go hand in hand after somebody either has had brain damage or developmental deficits,” said study senior author Brad Duchaine, a professor at Dartmouth.

"That co-occurrence is probably due to the two abilities depending on neighbouring brain regions in the temporal lobe," Duchaine said in a statement.

Dr. Vinit Suri, Senior Consultant, Neurology, Indraprastha Apollo Hospitals, New Delhi noted that the exact mechanisms by which long Covid may cause face blindness are not yet fully understood, but there are several possible explanations.

"Firstly, long Covid can cause a range of neurological symptoms which may affect the brain regions responsible for face recognition, causing difficulty in processing visual information and recognising familiar faces," Suri told PTI.

"Secondly, Covid-19 can cause inflammation and damage to the blood vessels, which can lead to reduced blood flow to the brain. This can cause brain damage and cognitive impairments, including face blindness," he added.

The research team conducted a series of tests with Annie to evaluate her problems with face recognition and determine whether she also has difficulties with other perceptual or cognitive abilities.

In one test, Annie was sequentially presented with 60 images of celebrity faces and was asked to name them. Annie correctly identified 29 per cent of the 48 celebrities whom she was familiar with as compared to most people, who can correctly identify 84 per cent of familiar celebrities.

The second test was a doppelganger test. Annie was shown a celebrity's name and then presented with images of two faces: the face of a celebrity and that of someone similar, and was then asked to identify which face was the famous person.

She identified the celebrity in 69 per cent of the 58 trials, as compared to 87 per cent in the control group.

"Our results from the test with unfamiliar faces show that it wasn't just that Annie couldn’t recall the name or biographical information of a famous person that she was familiar with, but she really has trouble learning new identities," said Kieseler.

The research team also obtained self-reported data from 54 individuals who had long Covid with symptoms for 12 weeks or more, and 32 persons who had reported that they had fully recovered from Covid-19.

Most respondents with long Covid reported that their cognitive and perceptual abilities had decreased since they had Covid.

"It was not just a small concentration of really impaired cases but a broad majority of people in the long Covid group reported noticeable difficulties doing things that they were able to do before contracting Covid-19 without any problems," Kieseler said.

"Our study highlights the sorts of perceptual problems with face recognition and navigation that can be caused by Covid-19 -- it is something that people should be aware of, especially physicians and other health care professionals,” Duchaine added.

Dr. Atul Prasad, Principal Director & HOD Neurology, BLK-Max Super Speciality Hospital, New Delhi said this is the first report of long Covid causing prosopagnosia.

"The more we study the virus, the more we realise how much damage it can cause during acute infection and now after infection has settled," Prasad told PTI.

Suri noted that that not all people with long Covid will develop face blindness, and the severity and duration of symptoms can vary widely.

"Further research is needed to better understand the relationship between long Covid and face blindness and to develop effective treatments and interventions for those affected," he added.

Eid al-Fitr 2025 was marked with grand celebrations across the Middle East, as millions of Muslims came together to pray, feast, and rejoice. However, amid the festivities in Saudi Arabia, the UAE, Qatar, and Kuwait, Gaza stood in mourning. The ongoing conflict and devastation in Palestine turned what is usually a time of joy into a period of sorrow and survival for many Palestinians. While some regions witnessed fireworks and public gatherings, Gaza endured airstrikes, hunger, and loss, painting a stark contrast to the celebrations elsewhere.

Gaza: Eid Amid Destruction and Mourning

In Gaza, the usual festive spirit of Eid was shattered by grief and destruction. Israeli airstrikes claimed the lives of several civilians, including women and children, leaving families mourning rather than rejoicing.

The usually vibrant markets of Gaza, once filled with people buying sweets and new clothes for Eid, remained eerily silent. Many families had no food to prepare the traditional celebratory meals, as ongoing blockades and supply shortages have left residents struggling for survival.

President Mahmoud Abbas declared that this year's Eid celebrations should be limited to religious observances, acknowledging the suffering of the people. In place of festivities, prayers were held for the victims of the war, and aid organizations worked tirelessly to distribute basic necessities to displaced families.

Saudi Arabia: Grand Celebrations Despite Regional Tensions

In stark contrast, Saudi Arabia witnessed grand celebrations with large-scale public events, concerts, and fireworks. The General Entertainment Authority (GEA) organized festivities across Riyadh, Jeddah, and other major cities. The night skies were illuminated with dazzling fireworks in places such as Boulevard World (Riyadh), Jeddah Art Promenade, and Al-Khobar Corniche.

Despite the revelry, many Saudi citizens expressed solidarity with Palestinians, with social media campaigns and fundraising efforts aiming to support those suffering in Gaza.

United Arab Emirates: A Festival of Luxury and Giving

The UAE celebrated Eid al-Fitr with traditional prayers, family gatherings, and a wide range of entertainment events. Dubai and Abu Dhabi hosted special cultural performances, and malls offered discounts and attractions for families.

However, amidst the celebrations, many mosques in the UAE emphasized the importance of charity, urging people to contribute to humanitarian efforts in Gaza and other conflict zones.

Qatar: A Blend of Joy and Concern

Qatar marked the beginning of Eid on March 30, 2025, with three days of public holidays and an extended break for government employees. Doha’s Corniche and Katara Cultural Village became focal points for celebrations, with thousands gathering to enjoy fireworks and live performances.

Nevertheless, Qatari authorities and charities continued their relief efforts for Palestine, highlighting the contrast between the joyous Eid atmosphere at home and the suffering of their fellow Muslims in Gaza.

Kuwait: Extended Holidays and Reflection

In Kuwait, Eid holidays provided a nine-day break for many employees, allowing families to come together in celebration. Traditional meals and prayers remained central to the festivities, but Kuwaiti media and religious leaders also focused on the plight of Palestinians, urging the public to donate and raise awareness.

A Tale of Two Realities

Eid al-Fitr 2025 presented a stark contrast between different parts of the Muslim world. While countries like Saudi Arabia, the UAE, Qatar, and Kuwait indulged in celebrations, Gaza stood in ruins, mourning its dead and struggling to find basic resources.

The divide between those celebrating and those suffering was more evident than ever, making this Eid a time of reflection for many Muslims worldwide. The call for peace and justice in Palestine echoed throughout sermons and speeches, reminding the world that while the spirit of Eid is about joy and gratitude, it is also about unity, compassion, and standing with those in need.

Gaza’s health ministry says Israel’s renewed savagery has led to the massacre of at least 970 people in 48 hours.

The wave of deadly airstrikes that shattered a fragile ceasefire in Gaza on Tuesday has so far claimed the lives of at least 970 people across the besieged territory, the health ministry said in a statement on Wednesday.

Before the resumption of the offensive, the death toll from the regime’s 15 months of genocidal war recorded by the ministry at midday on March 17 stood at 48,577.

By midday on Wednesday, the figure had risen to 49,547, the ministry said.

The health ministry also registered "one death and five severe injuries among foreign staff working for UN institutions.”

It said Israel attacked a UN headquarters in Deir el-Balah, in the central Gaza Strip, on Wednesday.

The victims had been taken to the Al-Aqsa Martyrs Hospital, the health ministry said.

Israel's military denied attacking a UN building in Gaza.

The UN Office for Project Services (UNOPS) confirmed the death of one of its staff by an explosive that was "dropped or fired" on its building in Deir el-Balah.

"An explosive ordnance was dropped or fired at the infrastructure and detonated inside the building,” it said, adding that five others were injured.

UNOPS Executive Director Jorge Moreira da Silva said he was "shocked and devastated" by the death of a staff member.

“This was not an accident.”  he said, adding that "attacks against humanitarian premises are a breach of international law."

Bulgaria's foreign ministry said later in the day that one of its citizens working for the United Nations was killed in Gaza, without specifying where in the territory.

Benjamin Netanyahu of Israel threatened on Tuesday that the massacre of women and children in Gaza was “only the beginning.” He stands accused of committing war crimes and ethnic cleansing in Gaza.

Millions of people across Iran and the world took to the streets on International Quds Day, expressing solidarity with Palestinians and condemning Israel’s actions in Gaza.

Brigadier General Ramezan Sharif, spokesperson for Iran’s Islamic Revolution Guards Corps (IRGC) and head of the Intifada Committee in Tehran, stated that rallies began at 10:00 a.m. local time (0630 GMT) in over 900 cities across Iran.

Demonstrators from various walks of life carried Iranian and Palestinian flags, as well as banners reading “Free Palestine” and “Al-Quds Must Be Liberated.” Flags of regional resistance groups, including Iraq’s Popular Mobilization Units (Hashd al-Sha'abi), Lebanon’s Hezbollah, and Yemen’s Ansarullah, were also displayed.

Mass rallies were held across West Asia, including in Iraq, Yemen, and Lebanon, as well as in other parts of the world.

Iranian Leaders Condemn Western Stance

Senior Iranian officials participated in the rally in Tehran, where Parliament Speaker Mohammad Baqer Qalibaf addressed the gathering.

“Iranians have taken to the streets in a massive show of support for Palestine and the Islamic Ummah,” Qalibaf said. “The Palestinian struggle is not just an issue for the Islamic world but a lesson for all of humanity.”

He criticized the West’s response to Israeli actions in Gaza, calling it a stain on Western civilization. “These crimes will be remembered as a lasting ignominy, exposing the West’s duplicity in human rights advocacy,” he added.

Qalibaf also defended the October 7, 2023, Palestinian attack on Israeli-occupied territories, describing Operation al-Aqsa Flood as a “rightful and legitimate response to 77 years of oppression by Israel, the U.S., and Britain.” He further described Israel as a “spare regime” dependent on U.S. support.

Quds Day: A Global Symbol of Resistance

Al-Quds Day, observed annually on the last Friday of Ramadan, was established in 1979 by the late Imam Khomeini to demonstrate solidarity with Palestinians and oppose Israeli occupation. The event has since become a symbol of resistance, with large rallies held worldwide, particularly amid Israel’s ongoing military operations in Gaza and the West Bank.
