Covid-19 is complex. It can affect the nervous system, leading to language disorders, strokes and seizures. Scientists are still trying to understand why. 75% of people hospitalised with the virus continue to suffer from secondary symptoms at least six months after they recover. Many find it hard to function in their daily lives. Researchers hope understanding Covid’s impact on the brain could pave a way for treatment.
Almost 2 billion doses of Covid-19 vaccine have been administered worldwide to date. But is it enough to wipe out Sars-CoV-2? Of course, those shots are not evenly spread across all continents. In terms of sheer numbers,
North America and Europe managed about 370 million shots each. South America with Covid-stricken countries like Brazil has a lot of catching up to do. Africa and its more than 1.3 billion people only received 34 million doses so far while Asia is storming ahead with more than 1 billion shots. But that doesn’t mean Asia is fully vaccinated. Far from it.
There are huge gaps, like in Vietnam, a country that has long been praised for its response to the pandemic. Now it is faced with new outbreaks and a new variant.
In February 2021, India and Pakistan agreed to strictly observe all previous agreements on ceasefire along the Line of Control in Jammu and Kashmir and other sectors, and to address core issues and concerns. It was their first joint statement in over eight years. But will the agreement be upheld this time? Both countries have come close to an all-out military conflict several times in the past two decades. DW takes a look at factors that are driving the hostility between the two South Asian neighbors.
Jaguars roam the rainforests of South America silently and well camouflaged. But their habitat is dwindling and ranchers see them as a threat. Yet two brothers are fighting misconceptions and want to project them.
The risk of dying from COVID is much higher than getting a blood clot from a vaccine. But even more concerning is a new report from Oxford University that shows catching the coronavirus puts you at even more risk of a deadly blood clot. Each delay puts more lives at risk, as the coronavirus spreads. It’s a balancing act between speed and caution in the fight against COVID-19.
The rollout of the Johnson & Johnson vaccine has been paused in the US, Europe and South Africa after reports of rare blood clotting in a very small number of people. Health authorities said they were halting the use of the shot while they investigate the cases — and that they were doing this out of “an abundance of caution.” The Astra Zeneca jab was also recently temporarily suspended in some countries after being linked to rare blood clots. Authorities are calling it a short “pause.” The US’s Johnson and Johnson vaccine has hit the same stumbling block as the UK’s AstraZeneca jab did last month: a likely link to a rare and deadly blood clot. Use of Johnson and Johnson’s Janssen vaccine has now been halted across the US, Europe and South Africa, with health authorities investigating six incidents of clotting in younger women, one of them fatal. The US-developed vaccine uses an adenovirus to trigger immunity – the same mechanism as the UK’s AstraZeneca vaccine. It accounts for roughly 5 percent of vaccines delivered so far in the US. This is a setback to Europe, too. Johnson and Johnson announced it will delay it’s rollout on the continent. The company had already started processing an order from the EU of 200 million doses. The Janssen jab has been partially rolled out in Africa, where a majority of countries don’t have enough vaccines even for their healthcare workers. The African Union signed a deal for 220 million doses this year. But US authorities remain hopeful. They’re saying it could only be a matter of days before the rollout resumes.
