What you should know about coronaviruses, including who is at risk and how to protect yourself.

A new coronaval disease warning has been issued for the United States and Canada to inform people of possible coronaviral disease risks associated with contact with hair and scalp.

The Centers for Disease Control and Prevention said it is also advising Americans to stay home if they have a history of hair loss or if they are considering getting a hair transplant.

People who have ever had a hair loss should avoid contact with scalp and face if at all possible, the CDC said.

Cancer and other diseases that can lead to hair loss include:Ovarian cancer (CRC): It is thought that about 25 million people worldwide have a genetic mutation that predisposes them to developing prostate cancer.

There is no specific risk for people with a mutation.

Menopause (menopausal): A woman’s age is often the most significant factor in the risk of developing CIN.

The average age of women who die of cancer in the U.S. is 65.

Women who are at the highest risk are those who have a CIN-associated mutation.

Menopausable hair loss is most common in people with mutations that cause CIN in the PAM1 gene and the RAR2 gene, the new advisory said.

The risk for menopausal hair loss and related hair loss due to mutations in the SLC6A4 gene and its related gene is greatest in the older adults and in the elderly.

The warning is not specific to hair products.

“People should be aware of the increased risk of hair and hair loss in people who are currently receiving chemotherapy or other medications for cancer, especially those who are older and are not taking their medications as directed by their doctors,” said Dr. Elizabeth F. Toth, a medical epidemiologist and head of the UMC’s Center for Preventive Medicine.

Families who have been living together may also be at greater risk, the advisory said, citing research that found people with multiple generations living in the same household had higher risk of CIN than the general population.

Those with the most severe hair loss may have hair loss that is more severe than people with no hair loss.

People who use hair removal products or scalp treatments should be alert to the risk, especially for people who have had CIN and are currently taking medications, according to the advisory.

Other important precautions include avoiding contact with facial hair, washing your hands frequently, wearing long-sleeved shirts or pants, and avoiding alcohol.

Tests should be performed on hair and skin to make sure the mutation is not present.

Anyone with a history or current history of CIR should contact their doctor immediately if they notice any hair loss on their face or scalp, the agency said.
