In the past two years, most COVID-19 patients exhibited three primary symptoms: fever, persistent cough, and loss or change in taste or smell. According to the Times of India, the emergence of new variants has drastically altered the symptoms beyond these three common signs, making early recognition of the infection somewhat complex.
Reports indicate that the new Omicron variant can lead to some uncommon symptoms. Researchers in the UK have found that only 50% of confirmed COVID-19 cases display the classic three symptoms, while only 20% are currently experiencing issues with smell and taste. Scientists have identified additional symptoms that patients infected with the Omicron variant experience, often along with cold-like feelings. Experts note that there are other signs not typically associated with respiratory issues that can go unnoticed, such as rashes, delirium, and loss of appetite.
**Rash**
Rashes can occur for various reasons, including allergies, exposure to high temperatures, and even infections. COVID-19 can lead to rashes on the skin, hands, toes, mouth, and tongue. It is a symptom of the Omicron infection observed in many individuals who tested positive. Rashes caused by COVID-19 are typically itchy, may worsen at night, and could lead to insomnia. Some people may also experience sensitivity to ultraviolet light along with the rash.
**Delirium**
Delirium is a disruption in mental functions that may lead to confusion and reduce awareness of the surrounding environment. This condition is also linked to COVID-19 and primarily manifests among older patients. Delirium symptoms can occur suddenly within days after contracting the virus. Elderly patients may become easily confused and behave oddly after being diagnosed with COVID-19, but these symptoms tend to resolve on their own after recovery from the infection.
**Loss of Appetite**
One in three COVID-19 patients experiences a loss of appetite or a desire to skip meals. A COVID-19 patient may find it unappetizing to eat for more than a week after infection, leading to weight loss and weakness. Additionally, skipping meals while suffering from COVID-19 can make it more challenging for the patient to recover from the infection as quickly as possible.
