Thecoronavirus pandemicis putting words in the mouths of billions of of us worldwide. Safe haven in place, COVID-19, homemade masks, PPE, home testing kits. These terms now accomplish a lexicon that’s grow to be part of daily conversation as the virus, which has now killed more than 29,000 of us around the globe, continues to spread.

It be an unsettling time. Educating your self on the science and the social responses to the COVID-19 outbreak will enable you to understand the situation and merit explain it to others.

If all of these key terms, congratulations on being so thoroughly informed. If no longer, this handbook willl enable you to brush up on the critical terms to get along in a coronavirus world. We will continue to update this story as our social response to the virus evolves.

Coronavirus lockdown: Why social distancing saves lives

Sustain track of the coronavirus pandemic.

Unusual coronavirus and SARS-CoV-2

No, the virus identified to have infected over 400,000 of us is rarely always actually named “coronavirus.” The be aware refers to any in a family of viruses whose structurepresents crownlike spikes when seen beneath a microscope. The term “glossy coronavirus” is a general term for the present kind we’re fighting. It became a fixture sooner than the virus was given an official name:SARS-CoV-2.


You may be tempted to utilize COVID-19 as a synonym for coronavirus, however that will confuse matters.COVID-19 is the name of the diseasethat the glossy coronavirus causes. It stands for “coronavirus disease 2019.”

The disease brings on flulike symptoms, however dangerously affects the lungs by filling them with fluid at a rapid rate. Patients with shameful cases may want respirators and oxygen to merit them breathe, usually for weeks. The fear is thatfatalities will occurwhen patient want for ventilators outstrips the present.

N95, surgical and homemade face masks

COVID-19 is a respiratory illness, and coronavirus spreads thru vaporized droplets. N95 respirator masks are the most effective kind that can give protection to you from acquiring SARS-CoV-2. Any various variety, including surgical masks and homemade, are no longer proven to be effective at blocking the virus, which canremain in the air for up to 30 minutes

So why enact some of us continue to wear surgical masks? And what about the fashion of homemade face masks you sew your self? Some health care facilities may be in dire straights, and wearing any accomplish of mask may present some with peace of mind on the speculation that some physical barrier is healthier than none at all. Others may well feel ailing and want to present a barrier from their coughs and sneezes as a courtesy to you. And soundless others may no longer be fully informed about the limitations of surgical or homemade masks. 

Then again, in case you have N95 or surgical masks at home, the medical community isasking for donations to merit curb the shortageof masks.

Hand-washing, social distancing and self-quarantine are thought to be much less complicated measures for ordinary residents, and the medical community asks to save N95 masks for his or her nurses and doctors, who are in the most uncovered and in greatest want of safety.

At-home coronavirus assessments

Exams kits for COVID-19 that you can administer at homeare being explored by the medical community and the FDA. The coolest thing about being able to find out in case you acquired the virus without leaving the home — potentially exposing others or your self — is appealing. Then again, articulate-to-user testing kits aren’t authorized by the FDA at this point, and some fear that assessments resulting in false negative results may well endanger healthy of us if the test-taker is actually distinct for SARS-CoV-2. 


Personal protective equipment, or PPE, refers to any gear necessary to minimize a person’s exposure to harmful materials that may well cause illness or injury — gloves, stout body suits, protective eyewear and so forth. In the case of the coronavirus pandemic, N95 masks (more on them beneath) for health care workers are in critically fast present.


The World Health Organization, usually called WHO, is the global body that’s grow to be a clearinghouse of information, research and safety guidelines. SARS-CoV-2, then referred to merely as glossy coronavirus, was first reported to the WHO on Dec. 31, 2019, days after the primary patients had been hospitalized in the Chinese metropolis of Wuhan.

PCR testing

A testing protocol to identify in case you have got got contracted the SARS-CoV-2 coronavirus. This test works by identifying the virus’ DNA thru a path of called PCR, or polymerase chain reaction. The PCR test appears for telltale markers distinct to this viral strain. The sample can be obtained thru a throat or nasal swab, which makes it ideal for the kind of drive-thru testing centers proposed in international locations admire the US. More details about coronavirus testing here.

Distinct versus presumptive cases

How enact in case you is perhaps infected with the recent coronavirus? Listing your symptoms is rarely always satisfactory. Distinct, or confirmed, cases are identified with lab assessments. Presumptive cases are no longer. Whenever you is perhaps exhibiting symptoms per COVID-19 — including fever, a dry cough and fluid accumulation in the lungs — and have had contact with a confirmed case, you is perhaps soundless thought to be presumptive.


Keeping those hands germ-free is essential.

Group spread

SARS-CoV-2 is extremely contagious, spreading thru “respiratory droplets” (a cough, sneeze, transfer of saliva) and contaminated objects, admire a door handle or various shared surfaces. Person-to-person spread means you can trace how the disease obtained from one person to another thru articulate contact, admire shaking hands. Group spread refers to of us in the same location contracting the virus without an glaring chain of occasions.

Group spread is an early sign that a disease can rapidly affect local, even global, populations. Read more at the Facilities for Disease Sustain watch over and Prevention.

Social distancing

In addition tothorough hand-washing, the WHO and CDC counsel the practice of social distancing to gradual the spread of COVID-19 by keeping at least six toes away from others, refraining from touching and by staying indoors, especially in case you is perhaps over 60, immunocompromised or suffering from an underlying condition. Local and national governments have responded by limiting gatherings of of us, ranging fromno more than 10 of usto 50 or 250 and even 1,000.

Self-quarantine, self-isolation

These that largely stay inside their have home, lodge room or various space are said to self-quarantine or self-isolate. For example, many governments are asking travelers returning from afflicted areas to self-quarantine for two weeks. Then again,there’s a technical incompatibility. Quarantine refers to those that appear healthy, however can be at danger for exposure or infection. Isolation refers to separating distinct or presumptive cases (see above) from the healthy population.

Mitigation, no longer containment

This phrase acknowledges that at pandemic proportions, nations can’t contain the spread of coronavirus. However with social distancing, self-quarantine and isolation, the burden of COVID-19 can be mitigated. In various words,slowing down the rate of infectioncan increase chances of survival by avoiding overcrowding hospitals, running fast on pivotal presents sooner than they can be replenished and overworking medical staff. Right here’s a deeply sobering account of what happens when the COVID-19 disease overwhelms medical and reinforce programs.

Pandemic versus epidemic

WHO officially declared the coronavirus SARS-CoV-2 a pandemic on March 11. The be aware “pan” (which roughly means “all”) refers to the global nature of the spread, affecting virtually each country and spot around the globe. An epidemic refers to a more localized spot. Sooner than reaching places admire the US, coronavirus was thought to be an epidemic in China’s Hubei province, and then in the country itself. Right here’s more on pandemics versus epidemics

Flatten the curve

Without mitigation, social distancing and all the leisure, epidemiologists and various health experts predict a sharp increase in COVID-19 cases that appears admire a tall, narrow spike on a graph. By following guidelines, the projected mannequin appears shorter and spread out over time. The curve isflatter, milder, much less pronounced. The hope of flattening the curve is to decrease fatalities by buying hospitals time to treat and scientists time to glimpse therapies and create a vaccine.

Safe haven in place

On March 16, six counties in the San Francisco Bay Areaordered residents to “safe haven in place,” a directive aimed at keeping of us in their homes for three weeks, with the reveal widened to the total state a few days later. It be nowbeing implemented around the realm. All nonessential businesses are shuttered, and apart from shopping for gadgets admire groceries and pharmaceuticals, picking up food and taking walks while maintaining a distance of six toes from others, locals are expected to stay inside. It be a fairly strict measure aimed at curbing community spread.

Vulcan greeting

You’re no longer shaking hands, kissing or patting of us on the back. These elbow and toe taps are out, too. Instead of usual cultural strategies for saying whats up, one internet meme advised greeting of us the Vulcan way, by flashing afictional hand signal for “live lengthy and prosper.” Right here are13 various touch-free ways to say “hi there.”

An abundance of caution

The preemptive closure of places of work, businesses and faculties ahead of distinct cases has usually been met with the phrase “due to an (over)abundance of caution.” 

70% isopropyl alcohol

Washing thoroughly with soap and wateris the handiest way to cancel the coronavirus on the skin, however surfaces can be harder to disinfect. Consultants say that disinfectant wipes and spray, and solutions made with 70% isopropyl alcohol arealso effective at destroying the virus’ structure. However be careful.Making your have hand sanitizer and various cleaning agentscan be dangerous, and is rarely always instantaneous.

Zoonotic disease

How did coronavirus come to be? What scientists know is that coronaviruses are transmitted between humans and animals — that’s the “zoo” in “zoonotic.” It be believed that the virus may have originated in a live animal market in Wuhan, a metropolis in the Hubei province of China, with a diseased animal transmitting it within contributors of the local population. Various zoonotic diseases include anthrax, rabies, Lyme disease, H1N1 (“swine flu”), West Nile virus, salmonella and malaria.
