For the latest news and information about the coronavirus pandemic, see the WHO website.

The Coronavirus Pandemic puts words in the mouth of billions of people worldwide. Local protection, self-isolation, COVID-19, homemade masks, PSA – these terms are now a lexicon that has become part of the daily conversation as the virus, which has now killed more than 24,000 people around the world, has spread

It is a troubling time. By learning about the science and social responses to the COVID 19 outbreak you can better understand the situation and explain it to others.

If you know all of these key terms, congratulations on being thoroughly informed. If not, we will help you refresh the critical terms to cope with a coronavirus world. We will continue to update this story as our social response to the virus evolves.

Novel coronavirus and SARS-CoV-2

No, the virus, which is known to have infected over 400,000 people, is not referred to as the "coronavirus". The word refers to all viruses in a family whose structure has crown-like tips under the microscope . The term "novel coronavirus" is a general term for the current type we are fighting. It became a fixed point before the virus was given an official name: SARS-CoV-2 .

COVID-19

You might be tempted to use COVID-19 as a synonym for coronavirus, but that will be confusing. COVID-19 is the name of the disease that causes the novel corona virus. It stands for "Coronavirus Disease 2019".

The disease leads to flulike symptoms, but has a dangerous effect on the lungs by quickly filling it with fluid. Patients with extreme cases may need respirators and oxygen to often breathe for weeks. It is feared that deaths will occur if the patient's need for ventilators exceeds care.

<h2>  N95, surgical and homemade face masks </h2>
<p>  COVID-19 is a respiratory disease and the coronavirus spreads through evaporated droplets. <span class= N95 respirators are the only type that can protect you from the purchase of SARS-CoV-2. Any other variety, including surgical and homemade masks, has been shown not to effectively block the virus, which can remain in the air for up to 30 minutes .

Why do some people continue to wear surgical masks? And what about the trend of homemade face masks that you sew yourself ? Some health care facilities may be in a difficult situation, and wearing a mask could give certainty that a physical barrier is better than none. Others may feel sick and want to form a barrier against coughing and sneezing for courtesy. Still others may not be fully aware of the limitations of surgical or homemade masks.

However, if you have N95 or surgical masks at home, the medical community is asking for donations to help alleviate the lack of masks .

Hand washing, social distancing, and self-quarantine are seen as more effective measures for ordinary people, and the medical community is asking to keep N95 masks for their nurses and doctors who are most at risk and in need of protection.

PPE

Personal Protective Equipment (PPE) refers to all items of equipment that are required to minimize a person's exposure to harmful materials that can cause illness or injury – gloves, body suits, goggles, etc. In the case the coronavirus pandemic, N95 masks (more on this below) are extremely scarce for healthcare workers.

WHO

The World Health Organization, often referred to as WHO, is the global body that has become a clearinghouse of information, research and security policies. SARS-CoV-2, then simply referred to as a novel coronavirus, was first reported to WHO on December 31, 2019, days after the first patients were hospitalized in the Chinese city of Wuhan.

Pandemic versus epidemic

The WHO officially declared the coronavirus SARS-CoV-2 a pandemic on March 11 . The word "pan" (which roughly means "all") refers to the global nature of the spread and affects practically every country and region around the world. An epidemic affects a more local region. Before the corona virus reached places like the USA, it was considered an epidemic in the Chinese province of Hubei and then in the country itself. Here is more about pandemics versus epidemics .

PCR test

A test protocol that can be used to determine whether you have been infected with the SARS-CoV-2 coronavirus. This test identifies the DNA of the virus through a process called PCR or polymerase chain reaction. The PCR test looks for telltale markers that differ from this virus strain. The sample can be taken with a throat or nose swab, making it ideal for the transit test centers proposed in countries such as the United States. More details about corona virus testing can be found here.

Positive versus suspected cases

How do you know if you are infected with the new coronavirus? Listing your symptoms is not enough. Positive or confirmed cases are identified with laboratory tests. There are no suspected cases. If you have symptoms related to COVID-19 – including fever, dry cough, and fluid in the lungs – and have had contact with a confirmed case, you are still considered suspected.

Distribution in the community

SARS-CoV-2 is highly contagious and spreads through "breath droplets" (coughing, sneezing, transmission of saliva) and contaminated objects such as door handles or other common surfaces. The spread from person to person means that through direct contact like shaking hands, you can follow how the disease got from one person to another. The prevalence in the community refers to people in the same place who become infected with the virus without an obvious chain of events.

The spread in the community is an early sign that a disease can quickly affect local, even global, populations. Read more in the Centers for Disease Control and Prevention.

Social distancing

In addition to thorough hand washing the WHO and CDC recommend the practice of social distancing to slow the spread of COVID-. 19 by staying at least one meter away from others, not touching and staying indoors, especially if you are over 60 years of age, immunodeficient or have an underlying disease. Local and national governments have responded by limiting the number of meetings of no more than 10 people to 50 or 250 or even 1,000.

Self-quarantine, self-isolation

People who mostly stay in their own house, hotel room or other rooms should put themselves in quarantine or isolate themselves. For example, many governments are asking travelers to return to self-quarantine from affected areas for two weeks. however, there is a technical difference . Quarantine refers to people who appear healthy but may be at risk of exposure or infection. Isolation refers to the separation of positive or suspected cases (see above) from the healthy population.

Mitigation, Not Containment

This sentence recognizes that pandemic nations cannot curb the spread of the coronavirus. But through social distancing, self-quarantine and isolation, the burden of COVID-19 can be reduced. In other words, slowing infection rates can increase survival by avoiding overcrowded hospitals, running out of essential supplies before they can be replenished, and overloading medical personnel. This is a deeply sobering account of what happens when COVID-19 disease overwhelms medical and support systems.

Flattening the Curve

Without weakening, social distancing and everything else, epidemiologists and other health professionals predict a sharp increase in COVID-19 cases that look like a tall, narrow peak on a graph. By following the guidelines, the projected model looks shorter and spread out over time. The curve is flatter, milder, less pronounced . The hope of smoothing the curve is to reduce deaths by giving hospitals time to treat and scientists to discover therapies and develop a vaccine.

On-the-spot protection

On March 16, six districts in the San Francisco Bay Area ordered residents to provide "on-the-spot protection" a policy aimed at Keeping people in their homes for three weeks A few days later, the order spread to the entire state. It is now being implemented worldwide . All non-essential stores are closed, and with the exception of shopping for items such as food and pharmaceuticals, picking up groceries, and walking two meters away from others, locals are expected to stay indoors. It is a fairly strict measure to curb the spread of the community.

Volcanic greeting.

They don't shake hands, kiss or pat people on the back. These elbows and toes are also out. Instead of the usual cultural methods of saying hello, an internet meme suggested that people greet people in a volcanic way by flashing a fictional gesture for "live long and prosper". Here are 13 other non-contact ways to say "hey".

An abundance of caution

The preventive closure of offices, companies and schools from positive cases was often answered with the expression "due to an (over) abundance of caution". ""

70% isopropyl alcohol

Thorough washing with soap and water is the best way to kill the skin coronavirus, but surfaces can be more difficult to disinfect. Experts say that disinfectant wipes and sprays as well as solutions with 70% isopropyl alcohol also effectively destroy the structure of the virus . But be careful. The production of your own hand disinfectant and other cleaning agents can be dangerous and is not recommended.

Zoonosis

How did the coronavirus come about? Scientists know that coronaviruses are transmitted between humans and animals – this is the "zoo" in "zoonosis". The virus is believed to come from a live animal market in Wuhan, a city in Hubei Province, China, and was transmitted by a sick animal to the local population. Other zoonotic diseases include anthrax, rabies, Lyme disease, H1N1 ("swine flu"), West Nile virus, salmonella and malaria.
