Where was the corona virus first discovered?
The first known infections from SARS-CoV-2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.
Coronavirus (or, as doctors and scientists call it, COVID-19) has been part of everyone’s life since mid-March 2020, when most schools, businesses, and communities quickly changed how they operated to prevent the spread of the virus. Because the disease infected a large number of people all over the world, experts call this a pandemic.
Scientists don’t know the exact origin of COVID -19, and they might never have all the answers. But they do know that some diseases start in animals before spreading to humans. These types of diseases are called zoonotic (pronounced zoh-uh-NAH-tik). Cows, bats, and camels are among the animals that have spread diseases to humans in the past. The COVID-19 disease is also zoonotic, with the first cases popping up in December 2019 in Wuhan, China. The affected humans were all connected to a nearby market that sold live animals.
Is Covid-19 caused by a virus or a bacteria?
The virus that causes COVID-19 is in a family of viruses called Coronaviridae. Antibiotics do not work against viruses. Some people who become ill with COVID-19 can also develop a bacterial infection as a complication. In this case, antibiotics may be recommended by a health care provider.
Globally, the COVID-19 pandemic has sickened more than 532 million people and claimed the lives of more than 6.2 million, according to John Hopkins University. The United States has the world’s largest number of cases — over 84 million — and more than 1 million deaths.
What were the symptoms of corona virus?
Symptoms of COVID-19 include respiratory illness with fever, cough, and difficulty breathing. Sometimes people experience chills and shaking, muscle pain, headache, sore throat, or a new loss of sense of taste or smell. In severe cases, COVID-19 can cause pneumonia and severe acute respiratory syndrome. People with chronic health conditions and the elderly are more likely than others to have a life-threatening case of the disease.
Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
Drugmakers around the world raced to find safe and effective vaccines against the coronavirus disease. The U.S. Food and Drug Administration (FDA) has authorized three COVID-19 vaccines for emergency use during the coronavirus pandemic: Pfizer-BioNTech, Moderna, and Johnson & Johnson. Pfizer-BioNTech received full FDA approval for individuals 16 years and older on August 23, 2021.
Researchers expect that as more people are vaccinated and become immune to COVID-19, the number of cases will continue to go down. Immunity to the virus means the body can fight it off and won’t spread it to another person. When enough people are immune to COVID-19 so that the illness is no longer a serious threat, that’s called herd immunity.
Experts say that for herd immunity to work in a community, between 75 and 85 percent of people need to be vaccinated. Almost 60 percent of Americans are fully vaccinated, depending on where you live: Some places are higher, and others are lower.
Life during the corona virus…
Lots of people helped their neighbors throughout the pandemic. First responders, like healthcare workers, police officers, and firefighters, kept people healthy and safe; essential workers such as grocery store employees, delivery drivers, and postal workers worked in-person to make sure other folks had what they needed to live.
What foods should we take to save ourselves from the corona virus?
Consume enough fibre because it contributes to a healthy digestive system and offers a prolonged feeling of fullness, which helps prevent overeating.
To ensure an adequate fibre intake, aim to include vegetables, fruit, pulses and wholegrain foods in all meals. Whole grain foods include oats, brown pasta and rice, quinoa and whole-wheat bread and wraps, rather than refined grain foods such as white pasta and rice, and white bread.
Good hydration is crucial for optimal health. Whenever available and safe for consumption, tap water is the healthiest and cheapest drink.
