<b><i>Introduction:</i></b> The course of anosmia and ageusia in COVID-19 patients is not yet clearly known. We present short-term follow-up data concerning mild to moderate disease in home-quarantined COVID-19 patients in Greece. <b><i>Methods:</i></b> We provided a symptom questionnaire and instructions for a self-administered home smell-and-taste test to 79 positive COVID-19 patients from 2 tertiary hospitals in Greece. The patients recorded their subjective symptoms before and during infection as well as 4 weeks after the diagnosis. The patients also underwent the home test during infection and 4 weeks later. <b><i>Results:</i></b> Twenty-nine patients (36.7%) reported a loss of smell, and 21 (27.8%) reported a loss of taste, with equal prevalences between genders. We observed 2 types of recovery, i.e., a rapid, almost complete recovery, and a second slower and partial recovery. The type of recovery was not age related. A rapid recovery was observed in two thirds of the patients, with their olfactory ratings presenting a trend towards significance in correlation with nasal obstruction. A slow recovery in olfaction was correlated with low intensity ratings in odors with a trigeminal compound. The loss of taste was more pronounced in sweet and salty intensity ratings. <b><i>Conclusion:</i></b> Chemosensory deficits associated with COVID-19 infection were quite frequent among the Greek patients with mild or moderate disease who, in most cases, returned to normal within 4 weeks. However, 1 in 3 patients presented with persistent olfactory and gustatory dysfunction in the short term.

Since the beginning of the pandemic, public health authorities have provided support to long-term care facilities (LTCFs) for the implementation of risk mitigation measures. Nevertheless, the necessity of these measures has been doubted, especially after vaccines and antiviral treatment became available. Here, we present the burden of COVID-19 infection in LTCFs during the first 9 months of 2022 across Greece. We tested the possible association of LTCF characteristics and public health response with the occurrence of clusters (two or more linked cases in LTCFs) with facilities recording one case as reference. After excluding LTCFs with sporadic cases, we tested the effect of the abovementioned variables on attack rate (cases/total number of persons in the LTCF). The disease burden in LTCFs was high and substantially varied among facilities, with hospitalization and case fatality rates ranging from 2 to 80% (median 14%, IQR 27%) and from 1 to 50% (median 5%, IQR 7%), respectively. The probability of transmission inside the facility increased when notification of public health authorities was delayed (p-value < 0.001) after adjusting for vaccination status and phase of the pandemic. Results showed that active support from public health authorities is still important in reducing the burden in LTCFs.
