Chinese health officials first reported cases of acute respiratory illness associated with a seafood and animal market in the city of Wuhan on December 31, 2019. A week later, they confirmed that a novel coronavirus, SARS (https://www.everydayhealth.com/pneumonia/guide/symptoms/)-CoV-2, was associated with this initial cluster of cases, according to the Centers for Disease Control and Prevention (CDC). The first confirmed case of COVID-19, the disease caused by SARS-CoV-2, in the United States was reported on January 21, 2020; by the end of March, the number of cases had climbed to 188,200, according to the Johns Hopkins University Coronavirus Resource Center.
A “novel” coronavirus (CoV) means it’s a new strain of coronavirus that hasn’t been seen or identified before.
Expert Doctor explains how we got to COVID-19 and what to expect now.
Coronaviruses can range from a common cold to more serious illnesses, like severe acute respiratory syndrome (https://www.everydayhealth.com/pneumonia/guide/symptoms/) (SARS). Symptoms can be mild, with just a runny nose or cough (https://www.everydayhealth.com/cough/guide/), but can also become much more serious, including fever and even pneumonia (https://www.everydayhealth.com/pneumonia/guide/). In some cases, a coronavirus can be fatal, especially in frailer people or those with preexisting medical conditions, such as heart disease or diabetes, notes the World Health Organization (WHO).
Must-Know Info About Coronavirus
Types of Coronaviruses
Human coronaviruses were first identified in the mid-1960s, and there are currently seven that can infect people. They include 229E (alpha coronavirus), NL63 (alpha coronavirus), OC43 (beta coronavirus), HKU1 (beta coronavirus), MERS-CoV, SARS-CoV, and SARS-CoV-2, the latest coronavirus to be transmitted to humans.
It is very common for people around the world to be infected with 229E, NL63, OC43, and HKU1. These viruses usually cause a mild to moderate upper respiratory tract illness — basically, a common cold, according to the CDC.
These coronaviruses can also cause lower respiratory tract illnesses, such as pneumonia and bronchitis (https://www.everydayhealth.com/bronchitis/) and people with cardiopulmonary disease or weaker immune systems are especially susceptible to it, as well as infants and elderly peopleПоділитися цим:
