Social Distance in COVID-19: Drawing the line between protective behavior and stigma manifestation.

Social stigma has long been defined by Ervin Goffman as an attribute that it is deeply discrediting and reduces the individual who bears it from a whole and usual person to a tarnished one, unfit to be included into the mainstream society.1 As stigma spans time and space and has been documented in other social species such as ants and chimpanzees, one might argue for its adaptive potential. Neuberg and colleagues2 have suggested that humans generate stigmas against threats to effective group functioning, with a notable case being infectious diseases. A similar explanation has been put forward by other researchers who consider stigma to have evolved from disease-avoidance mechanisms.3 Hence, it is not surprising that tuberculosis, HIV and leprosy have been surrounded by stigma and discrimination.4,5 More recently, people who had survived the 2013-2016 Ebola outbreak tackled social exclusion and unemployment after returning to their neighborhoods.6 Nowadays, the global community faces an unprecedented challenge of grappling with the COVID-19 pandemic. From the very outset, social distance measures were introduced in order to contain the spread of the virus, ranging from maintaining 1.5 meters physical distance to strict lockdowns. However, this may easily escalate into stigmatizing and discriminatory behaviours (desired social distance is a proxy of discrimination) against people who have suffered from COVID-19, their relatives and their caregivers, with the United Nations stating that "fear, rumours and stigma" are the key challenges surrounding COVID-19.7 Apart from the psychological distress experienced by the stigmatized individuals, due to anticipated stigma people might start concealing their illness, avoid or delay seeking medical advice or testing until they are seriously ill and be reluctant to collaborate with authorities on tracing contacts. Therefore, timely identifying stigma and addressing it is an integral part of an effective health response to the ongoing pandemic. In spite of its importance, research on COVID-19 related stigma is scarce. From the perspective of the stigmatized individuals, a study in China8 demonstrated that COVID-19 survivors faced heightened levels of overall stigma, social rejection, financial insecurity, internalized shame and social isolation, compared to healthy controls. From the perspective of the general population, a study in US9 substantiated low levels of anticipated stigma and stereotype endorsement; however, respondents who anticipated greater stigma were less likely to seek a COVID-19 test. It is therefore clear that the international literature is still on its infancy with respect to COVID-19 related stigma. In this context, in the First Department of Psychiatry, University of Athens, we conducted a survey on public attitudes to COVID-19 and to mental disorders. The study would inform the design and implementation of anti-stigma initiatives, funded by the Regional Governor of Attica. As physical distancing and social distancing are interwoven, with some researchers and practitioners using the terms interchangeably, and social distancing is also a protective public health measure against COVID-19, we enquired about attitudes and desired social distance from people who had recovered from COVID-19. Nonetheless, it merits noting that evidence from other diseases indicates that stigma may persist even after recovery.10 Moreover, rather than describing public attitudes overall, we were more interested in investigating where COVID-19 related stigma stands as compared to the most stigmatizing health condition to date, i.e., severe mental illness.11 Interestingly enough, which elements of severe mental illness render it the most stigmatized as compared to other conditions is still speculative: is it the fear of madness? the severity and the type of symptoms? the purported incurability or its chronicity? In our study, evidence from a convenience sample of 370 residents of Attica indicates that the general population holds more negative attitudes towards people who have recovered from COVID-19 than towards people with mental disorders. Nonetheless, respondents reported lower levels of desired social distance from recovered COVID-19 cases as compared to mental illness cases in social interactions of graded intimacy; however, the difference between the two groups was found to decrease as the level of intimacy decreased as well. In other words, desired social distance from COVID-19 cases is more easily discernible in transient social encounters, like talking to a stranger. It is therefore clear that social distance is still a public health protective measure rather than a stigma manifestation. For social encounters of greater intimacy, usually a sign of discriminatory behaviours, having recovered from COVID-19 is not a deterrent to interaction. Findings can be explained by the acute (non-chronic) nature of the disease, both in terms of symptoms as well as the 10-day period since symptom onset for being contagious. Nonetheless, with emerging evidence substantiating the notion of long COVID-19, defined as the persistence of symptoms for 3 weeks after infection,12 this might quickly change. Moreover, with many public health protective measures available, such as the use of mask, diagnostic testing and vaccination, people who become infected are more likely to be blamed for contracting the disease and thus deemed responsible for this, in line with the Attribution Theory.13 Specifically, overarching evidence from stigma research in many diseases/conditions indicates that when an illness or a social condition, such as economic disadvantage, is attributed to internal causes, as compared to external, lay people are more likely to hold stigmatizing attitudes.14-16 Therefore, as attitudes towards COVID-19 are worse compared to those towards people with mental illness, if tailored anti-stigma action is not undertaken, it is only a matter of time for prejudices to evolve into discriminatory behaviours, with devastating consequences on both the individuals and the course of the pandemic. Concomitantly, as severe mental illness is neither life threatening nor contagious, but COVID-19 is, it is interesting to explore how stigma is related to evolutionary mechanisms favouring adaptability and survival as well as which elements are the drivers of stigma development and establishment. Therefore, comparing and contrasting the stigma surrounding these conditions may shed light on the underpinnings of social stigma and facilitate effective interventions to reduce it and eventually eliminate it.

Balsamic type varietal vinegar from cv. Xinomavro (Northen Greece). Optimization and scale-up of the alcoholic fermentation step using indigenous multistarters.

Taguchi design was used to examine the effect of parameters that should be optimized in order to control the alcoholic fermentation of the concentrated grape must (CGM) from cv. Xinomavro using the best-performing indigenous Hanseniaspora uvarum and Saccharomyces cerevisiae strains as multistarters. The "optimum" combination of conditions (cell ratio of H. uvarum/S. cerevisiae; inoculum size and inoculation time of S. cerevisiae; fermentation time and temperature) resulted in an alcoholic product that meets ethanol (79 g/kg) and residual sugar (164 g/kg) content requirements for further use in the production of balsamic type vinegar. Multistarter fermentation affected positively the varietal organoleptic traits of the fermented CGM. 5-(Hydroxymethyl)-furfural content emerged as a critical factor for the standardization of this process. Scaling up experiments in 12 L barrels verified findings from small scale in 100 mL flasks. The results of this work can be used as a prototype in further similar efforts.

Devastating epidemics in recent ages Greek populations

In the recent Greek ages the most devastating epidemics were plague, smallpox, leprosy and cholera. In 1816 plague struck the Ionian and Aegean Islands, mainland Greece, Constantinople and Smyrna. The Venetians ruling the Ionian Islands effectively combated plague in contrast to the Ottomans ruling all other regions. In 1922, plague appeared in Patras refugees who were expelled by the Turks from Smyrna and Asia Minor. Inoculation against smallpox was first performed in Thessaly by the Greek women, and the Greek doctors Emmanouel Timonis (1713, Oxford) and Jakovos Pylarinos (1715, Venice) made relevant scientific publications. The first leper colony opened in Chios Island. In Crete, Spinalonga was transformed into a leper island, which following the Independence War against Turkish occupation and the unification of Crete with Greece in 1913, was classified as an International Leper Hospital. Cholera struck Greece in 1853-1854 brought by the French troops during the Crimean War, and again during the Balkan Wars (1912-13) when the Bulgarian troops brought cholera to northern Greece. Due to successive wars, medical assistance was not always available, so desperate people turned many times to religion through processions in honor of local saints, for their salvation in epidemics.

Insights into metabolic disease from studying genetics in isolated populations: stories from Greece to Greenland.

Over the last 10 years substantial progress has been made in our understanding of the genetic basis for type 2 diabetes and related traits. These developments have been facilitated by technological advancements that have allowed comprehensive genome-wide assessments of the impact of common genetic variation on disease risk. Current efforts are now focused on extending this to genetic variants in the rare and low-frequency spectrum by capitalising on next-generation sequencing technologies. This review discusses the important contributions that studies in isolated populations are making to this effort for diabetes and metabolic disease, drawing on specific examples from populations in Greece and Greenland. This review summarises a presentation given at the 'Exciting news in genetics of diabetes' symposium at the 2015 annual meeting of the EASD, with topics presented by Eleftheria Zeggini and Torben Hansen, and an overview by the Session Chair, Anna Gloyn.

Active leprosy in Greece: a 20-year survey (1988-2007).

A retrospective study (1988-2007) of all newly detected (n = 26) and relapsed (n = 51) Greek cases of leprosy was carried out. Multibacillary types prevailed in both patient groups (n = 68, 88.3%). Seven immigrants from endemic areas were also referred with multibacillary leprosy. Newly detected Greek cases resided more frequently in rural areas. Incident and relapsed multibacillary disease cases did not differ by age. Diagnosis was mainly made on the basis of skin lesions rather than leprosy reactions. Leprosy in Greece (total population, ten million) has the epidemiological characteristics of a disease that is dying out, without gender inequalities.

The Greek moulages: a picture of skin diseases in former times.

Medical moulages are three-dimensional wax figures made for teaching in the beginning of the last century. A rather unknown hospital museum in Athens, Greece, stores 1660 moulages depicting skin and venereal diseases prevalent at that time such as syphilis, lepra and tuberculosis. The historical background behind the Greek moulages and the art of moulaging are described.

Yeast populations residing on healthy or botrytis-infected grapes from a vineyard in Attica, Greece.

The yeast flora associated with healthy and Botrytis-infected grapes was assessed. Molecular identification methods assigned isolates to six genera and nine species. For the first time Hanseniaspora opuntiae was encountered as an inhabitant of the grape ecosystem. By using DraI, an informative restriction fragment length polymorphism pattern was generated to distinguish H. opuntiae from the closely related organism Hanseniaspora guilliermondii. Botrytis infection resulted in a larger population and greater diversity of yeasts enriched with fermentative or spoilage species.

A case of feline leprosy caused by Mycobacterium lepraemurium originating from the island of Kythira (Greece): diagnosis and treatment.

A 2-year-old, 4 kg, healthy, domestic shorthair female cat presented with ulcerated subcutaneous nodules on the commissures of its mouth. The cat was negative for feline leukaemia virus and feline immunodeficiency virus. Skin mycobacteriosis was diagnosed after detection of numerous acid-fast bacilli in Ziehl Neelsen-stained smears from the ulcers. Feline leprosy was suspected following preliminary polymerase chain reaction results: positive for Mycobacterium genus but negative for Mycobacterium tuberculosis and Mycobacterium avium complexes. Mycobacterium lepraemurium was later identified following DNA sequence analysis of the 5' end of the 16S rRNA gene and the 16S-23S internal transcribed spacer region. Microscopic lesions consisted of pyogranulomas containing mainly large foamy macrophages with 10-100 intra-cellular acid-fast bacilli per field. The cat was cured after surgery and a 14-week course of clofazimine (30 mg daily) and clarithromycin (50 mg twice daily).

Current profile of active leprosy in Greece; a five-year retrospective study (1988-1992).

The epidemiological characteristics of newly diagnosed, active leprosy cases (incidence, N = 16 Greeks and 4 expatriates) and relapsed cases (recurrences, N = 25, all Greeks) were studied. Most of the cases were multibacillary, over 50% being lepromatous. The relapses were analyzed by sex, disease duration and residence (rural or urban). Most of the newly diagnosed cases presented with nonreactional skin lesions (70%). The relapses were self-reported and detected mainly because of type 2 leprosy reactions (56%). The main source of the infection for new cases was members of their former extended family. The statistical trend of leprosy in Greece is a continuing decline in a country which already has a very low endemicity.

Hepatitis B virus (HBV) serum markers in Greek leprosy patients.

The prevalence of HBsAg, anti-HBs, and anti-HBc in the sera of 217 patients with the two polar types of leprosy and 382 hospital controls was studied in order to investigate the degree of exposure of Greek leprosy patients to HBV and the ability of these patients to clear HBV from the blood. Two distinct serological patterns were analyzed: effective exposure, characterized by the presence of one or more of the three serological markers, and active infection, characterized by the presence of HBsAg. From the statistical analysis it was found that TT as well as LL cases had a higher prevalence of effective exposure in comparison to controls (p less than 10(-5) and p less than 10(-6)). No significant difference was found between the two polar leprosy types (p greater than 0.30) or between bacteriologically positive and negative LL cases (p greater than 0.30). As far as the prevalence of active infection is concerned among the effectively exposed subjects of all groups, no significant difference existed between TT cases and controls, LL cases and controls, the two polar leprosy cases combined and controls, the two polar leprosy groups, and LL cases positive and negative for Mycobacterium leprae (p for all comparisons greater than 0.30). It is concluded that leprosy cases are at a high risk of HBV infection, but the prevalence of active infection among those effectively exposed does not differ between leprosy cases and hospital controls.

Lepra, psora, psoriasis.

This article traces the curious history of how psoriasis came to be called by its present appellation. In retelling the story, psoriasis is seen as a disease (known since antiquity) that has been confused with leprosy, with some tragic results.
