For a Texas nurse, the first sign that something was wrong happened while brushing her teeth — she couldn’t taste her toothpaste. For a Georgia attorney, it was hitting a wall of fatigue on a normally easy run. When a Wisconsin professor fell ill in June, he thought a bad meal had upset his stomach.
But eventually, all of these people discovered that their manifold symptoms were all signs of Covid-19. Some of the common symptoms — a dry cough, a headache — can start so mildly they are at first mistaken for allergies or a cold. In other cases, the symptoms are so unusual — strange leg pain, a rash or dizziness — that patients and even their doctors don’t think Covid-19 could be the culprit.
ROME (AP) — The number of confirmed coronavirus cases worldwide topped 20 million, more than half of them from the United States, India and Brazil, as Russia on Tuesday became the first country to approve a vaccine against the virus.
Six to eight weeks. That’s how long some of the nation’s leading public health experts say it would take to finally get the United States’ coronavirus epidemic under control. If the country were to take the right steps, many thousands of people could be spared from the ravages of Covid-19. The economy could finally begin to repair itself, and Americans could start to enjoy something more like normal life.
ROME (AP) — The United States’ failure to contain the spread of the coronavirus has been met with astonishment and alarm in Europe, as the world’s most powerful country edges closer to a global record of 5 million confirmed infections.
For a spiky sphere just 120 nanometers wide, the coronavirus can be a remarkably cosmopolitan traveler.
Spewed from the nose or mouth, it can rocket across a room and splatter onto surfaces; it can waft into poorly ventilated spaces and linger in the air for hours. At its most intrepid, the virus can spread from a single individual to dozens of others, perhaps even a hundred or more at once, proliferating through packed crowds in what is called a superspreading event.
The soaring number of COVID-19 cases in the United States has far outstripped many local health departments’ ability to trace the contacts of those infected, a step critical in containing the virus’ spread.
