CONTAGION Definition & Usage Examples

The current CDC guidance for COVID-19 isolation varies by the severity of infection, with special consideration given to those who are moderately or severely immunocompromised. Concerning infectious shedding, the average duration is nine days for someone symptomatic for COVID-19 vs. only six days for someone asymptomatic for COVID-19. This is evidenced by the Delta variant, the 12th variant first seen in 2020. According to a study published in the Frontiers of Public Health, the duration of infectious shedding of the Delta variant was more than twice as long as the SARS-CoV-2 virus back in 2019.

In Atlanta, Department of Homeland Security representatives meet with Dr. Ellis Cheever of the Centers for Disease Control and Prevention (CDC) over concerns that the disease may be a bioweapon. Cheever dispatches Dr. Erin Mears, an Epidemic Intelligence Service officer, to Minneapolis where she traces everyone having had contact with Beth. She negotiates with reluctant local bureaucrats to commit resources for a public health response.

While there is significant variation in the risk of transmission, most cases follow the same general timeline once symptoms develop. All contagious diseases are infectious, but not all infectious diseases are contagious. Contagious diseases are infectious diseases that are easily spread through contact with other people. A contagious disease is one that can be spread from person to person. It can be shared through direct contact, like touching someone who is infected; indirect contact, like touching an object that is contaminated; or droplet contact, like inhaling the droplets expelled by an infected person talking, coughing, or sneezing.

  1. As a general rule, most people who get COVID-19 are no longer contagious 10 days after the appearance of symptoms or after testing positive for the virus.
  2. As Pesaran and Pick (2007) observe, however, financial contagion is a difficult system to estimate econometrically.[23] To disentangle contagion from interaction effects, county-specific variables have to be used to instrument foreign returns.
  3. For example, conversational partners who rate their conversations positively show similar speaking durations, rate of speech, and latencies of response.
  4. Whether someone develops symptoms is controlled by their level of immunity, which can be active or passive.
  5. In particular, Lang used an acoustic probe and measured the blinking component of the startle response — rapid blinking is characteristic of being startled.

When this happens, the immune cells that were once able to stop COVID-19 at the frontlines are less able to do so, increasing the risk of transmission. This includes people on chemotherapy, organ transplant recipients on immunosuppressants, and people with advanced untreated human immunodeficiency virus (HIV). This further reinforces the need for face masks and other preventive measures once isolation typically ends (after the fifth day following symptom onset or a positive test). This article explains how long COVID-19 is contagious and the variables that can increase or decrease the duration.

It also offers tips on how to protect others if you or someone know gets COVID-19. Other interventions, such as face masks and the avoidance of close contact, can help prevent the spread of the SARS-CoV-2 virus that causes COVID-19 once you leave isolation. Malaria (transmitted by mosquitos) is an insect-borne disease, and Lyme disease is tick-borne. Some of these general ways of spreading have earned special names that feature the word borne, a past participle form of the verb bear (“carry, transmit”). They include secretions, such as saliva, and body fluids, such blood, urine, and semen.

Madaline notes that “in some scenes,” the health care workers in the movie “wore personal protective equipment, which is what we normally do when caring for a patient who has a potentially transmissible disease.” For the novel coronavirus in China, he says, the period of time before transmission is possible is looking like five to six days. Our experts say Paltrow wouldn’t necessarily be able to transmit the virus that quickly after becoming infected.

Translations of contagion

A robust and well-functioning economy will be less vulnerable or susceptible to the financial crisis in other markets; that is, the changes in one market will not affect the said economy very harshly, or the impact gets dampened. After the crisis, many studies were conducted to understand how a crisis can transcend borders. During the study, plenty of examples were found, and economists realized that there was a global economic crisis almost every decade since 1825. Where social contagion processes become problematic is when there is a spread among people of harmful behaviors. Think about how a crowd of protesters might suddenly erupt into violence, as in the January 6th, 2021, attack on the U.S. Social contagion may also be blamed for waves of self-injurious behaviors, such as extreme diets, self-cutting, copycat shootings, and even suicide.

Realizing how your feelings relate to another person’s experience can make it easier to address them without acting on them. In the example above, your relaxed facial expression might help you feel calmer. You will also need to have two consecutive negative test results 24 hours apart to confidently end isolation. If not (or if your symptoms persist), you may need to isolate well beyond 20 days.

As early as 1759, economic philosophers such as Adam Smith observed that people imagine themselves in each other’s situations and display “motor mimicry” (Hatfield, 1993). There are also a great many words that mean the opposite of the word contagion. English language antonyms are also very useful grammatical devices to know. This list of antonyms for the word contagion is also provided by Power Thesaurus. The hysterical contagion swept the sleepover when the power went out as they were using the Ouija board.

Does Vaccination Reduce Contagion?

In particular, she’s committed to helping decrease stigma around mental health issues. You could also consider seeking support for yourself, as many therapists work with partners and family members of people living with mental health issues. This can be particularly tough if a loved one is dealing with a chronic mental health condition, such as depression. You can’t be of much help to them if you’re not feeling well, either. Mimicking an emotion typically evokes that emotion in you, and it then becomes part of your own experience. You begin to express it or relate it to others in the same way, and the process of contagion is complete.


Most countries saw personal incomes, prices, tax collection, revenues, and profits fall dramatically. This led to panic, and there was soon a recession; to avoid losses in fear of further drops, people started clearing the market and selling their assets, further worsening the crisis. Thus markets which are too dependent on one or few commodities are more susceptible to such shocks as a fall in demand or supply of the good can lead to massive changes in the equilibrium prices. For example, in the 19th century, much credit poured into Latin America after its independence from Spain. Eventually fearing massive outflows, the Banks raised their discount rates, leading to enormous panic and an eventual crisis in Europe with the stock markets crashing. On the other hand, a robust market can cushion the shock a country faces.

Mild or Asymptomatic COVID

An airborne disease, like tuberculosis, is spread through the air; airborne is especially used to describe diseases spread by germs that can survive in the air for hours. An infectious disease is caused by pathogenic microbial agents, such as viruses, bacteria, or other microorganisms. Pathogenic means “disease-producing.” Microbial refers to microbes, or microorganisms that can produce disease. Viruses are sometimes referred to as microbes because, like microbes, they are microscopic and can cause disease.

The Coronavirus Crisis

Earlier in Hong Kong, WHO epidemiologist Dr. Leonora Orantes and public health officials comb through security videotapes of Beth’s contacts in a Macau casino and identify her as the index case. Government official Sun Feng kidnaps Orantes as leverage to obtain a vaccine for his village, holding her for months. WHO officials provide the village with the earliest vaccines, and she is released. When she learns the vaccines were placebos, she goes to warn the village. Mitch stages a home “prom” for Jory after her boyfriend Andrew receives the vaccine, as life begins to return to normal. Active immunity means one’s body produces antibodies to fight off the virus or another disease-causing agent.

Scientists are unable to discover a cell culture to grow the newly identified MEV-1. Cheever determines the virus too virulent to be researched at multiple labs and restricts all work to one government site. Hextall orders UCSF researcher Dr. Ian Sussman to destroy his samples. Believing he is close to finding a viable cell culture, best trading journal Sussman violates the order and identifies a usable cell culture, from which Hextall develops a vaccine. Scientists determine the virus is spread by respiratory droplets and fomites, with an R0 of four when the virus mutates; they project that 1 in 12 of the world population will be infected, with a 25–30% mortality rate.
