First US COVID-19 case confirmed with unknown connection; no recent foreign travel or contact with traveler

A new coronavirus case in California could be the first in the U.S. that has no known connection to travel abroad or another known case, a possible sign the virus is spreading in a U.S. community, health officials said.

The Centers for Disease Control and Prevention reported the case Wednesday.

California officials said the person is a resident of Solano County, northeast of San Francisco, and is getting medical care in Sacramento County. They said they have begun the process of tracking down people who the patient has been in contact with, a process known as contact tracing.

Officials did not immediately release any other details.

All of the 59 other cases in the U.S. had travelled from abroad or had been in close contact with those who travelled. Health officials have been on high alert for so-called community spread.

Earlier U.S. cases included 14 in people who travelled back from outbreak areas in China, or their spouses; three people who were evacuated from the central China city of Wuhan; and 42 American passengers on the Diamond Princess cruise ship who were evacuated by the federal government to the U.S. from where the ship was docked in Japan.

Some of those evacuated were taken to Travis Air Force Base, which is in Solano County. A number of the earlier cases have been in California, including among some of the people taken to Travis and one in which a traveller who returned to San Benito County spread it to a spouse.

California officials have been preparing for the possibility that community spread of the virus might first surface there.

“We have been anticipating the potential for such a case in the U.S., and given our close familial, social and business relationships with China, it is not unexpected that the first case in the U.S. would be in California,” said Dr. Sonia Angell, Director of the California Department of Public Health and State Public Health Officer, in a statement.

The outbreak, which began in China, has infected tends of thousands of people in more than three dozen countries, with the vast majority in mainland China.

The new virus is a member of the coronavirus family that can cause colds or more serious illnesses such as SARS and MERS.

The virus can cause fever, coughing, wheezing and pneumonia. Health officials think it spreads mainly from droplets when an infected person coughs or sneezes, similar to how the flu spreads.

Officials are advising people to take steps to avoid infection with coronavirus or other respiratory infections like a cold or the flu, including washing hands with soap and water and avoiding close contact with people who are sick.

COVID-19 origins: Should we pay more attention to the lab leak theory and formally investigate it?

Image
A year and a half into the pandemic, we still do not know exactly where the SARS-CoV-2 virus, which causes Covid-19, came from. The prevailing view so far has been that the virus “spilled over” from bats into humans. But there are increasing calls to investigate the possibility that it emerged from a lab in Wuhan, China, where Covid first appeared at the end of 2019. So what do we know for sure, and what do we need still to find out? We know the sequence of the SARS-CoV-2 virus is close to that of bat coronaviruses . Several decades ago its “ancestor” was circulating in bat populations in southern Asia. But there are still many unanswered questions: we don’t know how the virus arrived in Wuhan, how its sequence evolved to allow human infection, and under what conditions it infected the first people who crossed its path. And for each of these stages, we don’t know whether there was a human contribution (direct or indirect). Zoonotic transmission pathways, in other words the pas

Menstrual cups are cheaper, more sustainable than pads and tampons for women

Image
Every year in America, women spend at least US$2.8 billion on sanitary pads and tampons that can take hundreds of years to decompose . Is there a more economical and environmentally friendly way? To find out, we asked Susan Powers , a professor of sustainable environmental systems at Clarkson University about her work comparing the environmental impact of tampons, sanitary pads and menstrual cups. What is a menstrual cup? A menstrual cup is a type of reusable feminine hygiene product. It’s a small, flexible bell-shaped cup made of rubber or silicone that a woman inserts into her vagina to catch and collect menstrual fluid. It can be used for up to 12 hours, after which it is removed to dispose of the fluid and cleaned. The cup is rinsed with hot water and soap between each insertion and sterilized in boiling water at least once per period. A cup can last up to 10 years . Although menstrual cups have been around for decades, they historically have been less popular than pads or ta

Human bodies respond to infections differently depending on the time of day

Image
When microorganisms – such as bacteria or viruses – infect us, our immune system jumps into action. It’s highly trained to sense and eliminate infections and clear up any damage caused by them. It’s typically assumed our immune systems work the exact same way regardless of whether an infection occurs during the day or at night. But research spanning over half a century now shows our bodies actually respond differently at day and night. The reason for this is our body clock, and the fact that each cell in the body, including our immune cells, can tell what time of day it is. Our body clock has evolved over millions of years to help us survive. Every cell in the body has a collection of proteins that indicate the time depending on their levels. Knowing whether it’s day or night means our body can adjust its functions and behaviours (such as when we want to eat) to the correct time. Our body clock does this by generating 24 hour rhythms (also termed circadian rhythms ) in how cells f
