The Centers for Disease Control and Prevention (CDC) has tripled the number of signs and symptoms for Covid-19.
The original symptoms included fever, coughing and shortness of breath. The new symptoms include muscle pain, headache, shaking chills, sore throat and loss of taste or smell. The symptoms appear 2 to 14 days after exposure to the virus.
A rare sign usually seen among the elderly population is reddened eyes, pink eye or eye irritation and itching.
Many adults report a loss of taste or smell. There are enough reports of this symptom to add it to the original list.
"If you have a sudden change in taste or smell... this may be the initial marker, so you would not want to be spreading it," said a CDC researcher.
The CDC warns that older adults over 50 and those with underlying, preexisting conditions such as diabetes, COPD, heart problems, HIV/AIDS, obesity, and asthma continue to be at high risk for Covid-19.
98% of people who test positive for Covid-19 recover after showing no symptoms or mild to moderate symptoms.
