Government, media and citizens: Watch out for the Nocebo Corona Effect
We are confronted on a daily basis with news about the Corona virus and its consequences. We read alarming headlines like 'Dutch becoming increasingly anxious about Corona virus' or 'Huge fears and stress about Corona crisis'.
Those headlines are part of the essential communication around Corona to make citizens aware of the very real danger of Corona and the importance of the preventive measures that are currently restricting our freedom.

Anxiety about the Corona virus and its effects is another factor having an enormous impact on daily life. In part, these fears serve a useful purpose. If the fear of contracting the virus can contribute to people maintaining a distance of 1.5 metres from one another, then it’s functional, not only for the individual but also for society. This kind of anxiety is a healthy and natural response to stressful circumstances.The other side of the coin is that anxiety can exacerbate all kinds of physical and psychological complaints, as well as having a negative influence on our behaviourand suppressing our immune system. So, what’s going on here?
How can worries about Corona intensify symptoms?
How can worries about Corona intensify symptoms?
When negative consequences of treatments and/or disorders are brought on by fears about these same treatments or disorders, we refer to this as the nocebo effect, the negative counterpart of the more familiar placebo effect. The nocebo effect is the result of negative expectations that an individual, patient or practitioner may have about a particular treatment, such as anxiety about the potential risks and side-effects or worries about catching an infection. This response can actually intensify the very symptoms people fear; it works on the basis of the ‘You get what you expect’ principle, and becomes a kind of self-fulfilling prophecy. How does that work?
Negative information
The most important factor behind the nocebo effect is the constant stream of negative information that we are exposed to every day of our lives. In the case of the Corona pandemic, we are bombarded daily with news about the rate of hospital admissions, the number of deaths, fears about infection or economic disaster scenarios, all of which receive far more attention than more positive issues in society such as our solidarity and resilience. In evolutionary terms, we are primed to prioritise this negative information and to remember the negative much better than the positive. This kind of negative feedback subconsciously triggers a stress reaction that raises our level of alertness and activates our fight-flight response. Information about diseases, risks or sideeffects can, through earlier experiences and conditioning (such as nausea caused previously by a medication resulting in these same physiological responses), lead to an increase in the symptoms. To make matters worse, reading an information leaflet can also make people reluctant to take the medication and can result in an increase in the symptoms described.
Early experiences
When stressful events pile up over a longer period of time, such as during the current Corona crisis, earlier experiences and conditioning can play a major role. A person who, for example as a child, had a traumatic experience in hospital, or who has been afraid of germs their whole life and is afraid of viruses is obviously more susceptible to the fear of catching the same virus themselves. These experiences don’t always have to be personal ones. Model behaviour means we also learn from the environment around us, and simply seeing other people having these experiences can cause the same nocebo effects.We know from long-term epidemiological studies that social isolation is a risk factor for greater morbidity and mortality.The current quarantine measures mean that some sections of the population have had social isolation forced upon them, and without social support, most people are more susceptible to such disorders as anxiety and feelings of depression. We know, for example, from research on stress that students are much more susceptible to viruses during exam periods, but also that any cuts and bruises they may have take longer to heal than during holiday periods.
