In response to the COVID-19 pandemic, many governments have taken drastic measures to avoid an overflow of intensive care units. Accurate metrics of disease spread are critical for the reopening strategies. Here, we show that self-reports of smell/taste changes are more closely associated with hospital overload and are earlier markers of the spread of infection of SARS-CoV-2 than current governmental indicators. We also report a decrease in self-reports of new onset smell/taste changes as early… 
The Link between Public Health Crisis and Presidential Approval: Evidence from the COVID-19 in South Korea
This study examines the relationship between the changes in the number of the COVID-19 confirmed cases and presidential approval ratings by using cases of infectious disease prevention management in
Google Searches for Taste and Smell Loss Anticipate Covid-19 Epidemiology
Findings suggest that Google searches numbers for olfactory and gustatory dysfunctions may help predicting the epidemiological trajectory of COVID-19 early before official reporting.
The autumnal lockdown was not the main initiator of the decrease in SARS-CoV-2 circulation in France
The results suggest that in France, the 2020 autumnal lockdown was not the main initiator of the decrease in SARS-CoV-2 circulation and curfews were important in achieving control of the transmission.
Global monitoring of the impact of the COVID-19 pandemic through online surveys sampled from the Facebook user base
In regions with strained health infrastructure but active social media users, it is shown it is possible to define COVID-19 impact trajectories using a remote platform independent of local government resources, and the best benchmarked UMD-CTIS signal is used.
Loss of Smell and Taste Can Accurately Predict COVID-19 Infection: A Machine-Learning Approach
It is concluded that smell and taste disorders are accurate predictors, with ML algorithms constituting helpful tools for COVID-19 diagnostic prediction.
Covid-19 and the criminalisation of viral transmission
The public is made cognisant that while parallels may be drawn between STI cases and coronavirus, both the mode of transmission (coughing versus sexual intercourse) and symptom presentation (non-specific versus pathognomic markers) are vastly different and come with their own inherent stigmas.
The sudden interest in smell impairment and growing frequency of online queries among the population can be used as an indicator of the spread of coronavirus infection among the Population as well as for evaluation of the effectiveness of COVID-19 epidemic control measures.
Modeling the effectiveness of olfactory testing to limit SARS-CoV-2 transmission
It is suggested that screening for olfactory dysfunction could be a high impact and cost effective method for broad COVID-19 screening and surveillance, and could reduce risk when used at point-of-entry for single-day events.
Olfactory loss is an early and reliable marker for COVID-19
Detection of early and reliable symptoms is important in relation to limiting the spread of an infectious disease. For COVID-19, the most prevalent symptom is either losing or experiencing reduced


Relationship Between Odor Intensity Estimates and COVID-19 Prevalence Prediction in a Swedish Population
Stochastic measures of odor intensity, if obtained in a large and representative sample, can be used as an indicator of COVID-19 disease in the general population and a large drop in olfactory performance is found.
Estimating the burden of SARS-CoV-2 in France
France has been heavily affected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and went into lockdown on 17 March 2020, and population immunity appears to be insufficient to avoid a second wave if all control measures are released at the end of the lockdown.
Self-Rated Smell Ability Enables Highly Specific Predictors of COVID-19 Status: A Case–Control Study in Israel
Self-reported quantitative olfactory changes, either alone or combined with other symptoms, provide a specific and powerful tool for clinical diagnosis of COVID-19.
Corona Viruses and the Chemical Senses: Past, Present, and Future
The analysis pinpoints the need for further studies to better quantify olfaction and taste disturbances associated with SARS-CoV-2 infection, compared to those of other viral and respiratory infections, and to understand how persistent are these disturbances after the infection has resolved.
Predictive Value of Sudden Olfactory Loss in the Diagnosis of COVID-19
Considering the high frequency of smell loss in non-hospitalized COVID-19 patients, acute olfactory impairment should be recognized as an early symptom of the disease and should be tested for on a regular basis.
A New Symptom of COVID‐19: Loss of Taste and Smell
The people with the greatest knowledge of current symptoms are the healthcare workers in the countries being most affected, yet they also have the least time to transmit this important information to the greater public.
Acute‐onset smell and taste disorders in the context of COVID‐19: a pilot multicentre polymerase chain reaction based case–control study
The use of STD assessment in anamnesis as a hint for COVID‐19 and to support individuals’ self‐isolation in the current epidemic context is suggested.
Preparing for a responsible lockdown exit strategy
This work proposes a framework for what is arguably the most difficult health challenge that governments have faced since the beginning of this century: a responsible lockdown exit strategy.
Loss of taste and smell
The urgent dental care provided was undoubtedly strenuous, but it was also a source of great satisfaction for the dentist, both personally and professionally.
