Stroke warnings often start days before: Here's what to watch for
Francis says that a stroke is most often caused by a clot that blocks blood flow to the brain, but in some cases, a burst blood vessel is to blame.
She explains that while the latter is more dramatic and sends people to the emergency room, the former (which accounts for 85% of cases) is more likely to be ignored until it's too late.
Francis notes that signs of a stroke can often appear and then disappear, which is why many people miss them.
These so-called "mini-strokes" or TIAs (transient ischemic attacks) can occur up to seven days before a major stroke.
Symptoms might include temporary speech issues, dizziness, or numbness and changes in vision - all of which demand urgent care.
Francis emphasises that lifestyle factors such as poor sleep, smoking, and lack of exercise continue to drive up stroke risk, especially among younger people.
She adds that chronic conditions like hypertension, diabetes, and high cholesterol also play a significant role, particularly in sub-Saharan Africa.
Francis also highlighted that women on oral contraceptives and people living with untreated infections like HIV or syphilis are increasingly vulnerable.

WHO recommends Gilead's twice-yearly injection lenacapavir for HIV prevention
The World Health Organisation (WHO) on Monday recommended Gilead's lenacapavir, a twice-yearly injection, as a tool to prevent HIV infection. The recommendation, issued at the International Aids Conference in Kigali, Rwanda, comes nearly a month after the US health regulator approved the drug, giving patients new hope of interrupting virus transmission. The twice-yearly injectable offers a long-acting alternative to daily oral pills and other shorter-acting options, reshaping the response to the disease especially among those who face challenges with daily adherence, stigma or access to healthcare. 'While an HIV vaccine remains elusive, lenacapavir is the next best thing,' said WHO director-general Tedros Adhanom Ghebreyesus. The WHO's recommendations come at a critical moment as HIV prevention efforts stagnate with 1.3-million new HIV infections in 2024 as funding challenges and stigma about the disease persist.

The UNAids Global Aids Update 2025, launched on 10 July, shows 'remarkable achievements' in the worldwide effort to combat HIV/Aids.
