Summary
Early diagnosis of Coronavirus disease 2019 (COVID-19) is vital. Olfactory and gustatory dysfunction were reported by two-thirds of European patients, highlighting their significance in non-laboratory diagnostics for COVID-19.
Area of Science:
- Infectious Diseases
- Epidemiology
- Otolaryngology
Background:
- The rapid global spread of Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, necessitates efficient diagnostic methods.
- Limited resources underscore the importance of accessible, non-laboratory diagnostic tools for early detection.
Purpose of the Study:
- To investigate the prevalence and significance of olfactory and gustatory dysfunction in European patients diagnosed with COVID-19.
- To assess the utility of sensory dysfunctions as early indicators for COVID-19.
Main Methods:
- A cross-sectional study design was employed.
- Data were collected from European patients with confirmed COVID-19 diagnoses.
- Patient-reported symptoms, specifically olfactory and gustatory dysfunction, were recorded.
Main Results:
- A significant proportion of COVID-19 patients reported olfactory dysfunction.
- A substantial number of COVID-19 patients reported gustatory dysfunction.
- Two-thirds of European patients with confirmed COVID-19 experienced these sensory changes.
Conclusions:
- Olfactory and gustatory dysfunction are highly prevalent in COVID-19 patients.
- These sensory symptoms serve as important indicators for the early diagnosis of COVID-19.
- Non-laboratory diagnostics, including the assessment of smell and taste, are crucial for managing the COVID-19 pandemic effectively.

11.0K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

11.8K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

01:24The Physiology of Taste
6.7K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...
