When the Spanish crossed the Atlantic and started arriving in hordes to begin their conquest and plunder of the Americas, they had a weapon in their arsenal that they had not anticipated: disease. Isolated indigenous tribes, who had no immunity to 'Old World' diseases like smallpox, measles, or influenza, among others, started dropping like flies overnight. Between 1545 and 1550, Aztecs from southern Mexico experienced a deadly outbreak of a mysterious illness, that took anywhere between 5 million and 15 million lives, nearly 80% of the population! It was colloquially called cocoliztli , meaning 'pestilence', but little was known about the reign of terror that this disease caused in this part of the world, until a few years ago. A groundbreaking study from 2017 published in Nature Ecology and Evolution was able to trace the outbreak to salmonella, a bacterial infection that causes a type of enteric fever nearly identical to typhoid. The demographic catastrophe unleas

A global population weary of the chaos caused by COVID-19 pandemic had to contend with a new, highly transmissible variant at the beginning of the year: Omicron. Omicron and on This latest version swept across Europe, leading to record weekly case numbers, although the number of deaths was relatively low, compared to previous outbreaks. And, although many countries began to relax lockdown and other restrictions on movements, the World Health Organization (WHO) pointed out that the disease is still a threat: by August, one million COVID-19 related deaths had been recorded in 2022. At the agency's World Health Assembly in May – the first to be held in-person since a pre-pandemic 2019 – the WHO chief, Tedros Adhanom Ghebreyesus, urged countries not to lower their guard. "Is COVID-19 over? No, it's most certainly not over. I know that's not the message you want to hear, and it's definitely not the message I want to deliver", he told delegates.

P eople who study infectious diseases and who work in public health have long known a bad pandemic would one day come. They knew such an event would overwhelm hospitals, strain supply chains, and place stresses on society that we would be ill-equipped to meet. Countries like the United States have for decades prepared to respond to such a crisis. But despite all the planning, the Covid-19 pandemic has, in myriad ways, not played out as expected. Three years after the first reports of a novel virus emerged from China, these experts admit that the microbe and the world's response to it have continuously deviated from their forecasts. In the hope that important lessons for next time can be found in the things we didn't anticipate this time, STAT asked 23 experts what had surprised them the most about the pandemic. The TL;DR version: We have a lot of learning left to do. Containment can buy time Ben Cowling, head of the division of epidemiology and biostatistics at the

Nausea could be down to diet, lack of sleep, or anxiety. Boy Anupong/Getty Images Nausea is sometimes a symptom of pregnancy, b ut people feel sick in the morning for many reasons. For instance, it could be down to diet, lack of sleep, or anxiety. Mild nausea can be treated with small changes, but if the problem persists, you should see a doctor. If you're a woman, feeling sick in the morning is known as one of the first signs you're pregnant. But it's not the only reason you might feel queasy when you wake up. "When we hear about morning sickness, most people's first thought is pregnancy," said Dr. Janice Johnston, the chief medical officer and cofounder of healthcare provider Redirect Health. "This is because morning sickness is a very common side effect in pregnancy, specifically in the first trimester, affecting about 7 in 10 pregnant women." The reason morning sickness is so common is due to a particular hormone called human chorionic gonadotrop
