COVID-19 causes symptoms that can be clear for up to 10 days. People with more severe forms of the disease will take longer to recover and can have up to two weeks. There are seven rare signs that COVID-19 experts warn people should be aware of because they may indicate COVID-19 infection.
Symptoms that have been reported but are not officially recognized include:
Skin rash on fingers and toes
Data from Zoe Cubid’s symptom research app, looking at the reported symptoms of sufferers in the UK, shows that some of the people who suffered from Covid-19 noted changes in their skin, including their toes.
It is not clear what causes these changes but may be related to the immune response to the virus.
The rashes are usually itchy and may make it difficult to sleep and can appear as prickly heat or a chickenpox rash, which are the most itchy red bumps.
Some people report changes in the mouth and tongue to the Zoe Covid app.
These include mouth ulcers and their tongue looks coated or patched.
Other changes include dry mouth and fungal infections as well as aches or muscles aches while chewing.

A hoarse voice
Hoarse voice is not a very common symptom of Cubid 19; However, at the beginning of the epidemic many clinical teams reported experiencing a hoarse voice during their illness which affected speech.
A hoarse voice can be heard and felt, different from person to person.
Some may notice their voice crackling, coarser, or rougher, quieter, or even changes in pitch.
If you have a hoarse voice, you may feel that it takes more effort to speak.
The COVID-19 virus affects the tissues in the human respiratory system of which the voice box (throat) is a part.
A small amount of people using the Zoe Symptom app have experienced significant chest pain, but it is important to remember that chest pain can be a sign of something wrong, such as a heart attack of a blood clot in the lungs.
It is most likely caused by the virus that directly affects the muscles and lungs.
While this is rare, people with Cubid who suffer from chest pain are at a higher risk of needing hospital support, especially if the chest pain is alongside confusion or shortness of breath.
Loss of appetite
Loss of appetite has been described as a possible symptom of the coronavirus virus.
Loss of appetite means that a person does not have the same desire to eat as before.
Signs of decreased appetite include unwillingness to eat, unintentional weight loss and lack of hunger no matter what time of day.
In fact, the idea of eating food may make a person feel nauseous, as if he may vomit after eating.
Delirium is an important symptom of Covid-19 in the elderly, according to Zoe researchers.
There are two types, hyperactive hallucination, in which someone suddenly changes his character and starts acting strangely, he may be agitated or distressed and even aggressive.
The second type is the hypoactive delirium, which is more common and more difficult to notice.
People who suffer from hypo-active hallucinations become withdrawn and less responsive or preoccupied with what is happening around them, and sometimes drowsy.
