The 2019‐nCoV outbreak occurred in Wuhan, China in December 2019(1). This unprecedented virus has caused global pandemic and over 2,300,000 cases worldwide in total number(2), which has been bringing tremendous pressure and challenges to medical institutions and clinical staff around the world. 2019‐nCoV can be transmitted by droplets primarily, while it has been reported that surface contact transmission exists as well(3). Keeping the integrity of skin barrier is a critical method to prevent the spread of 2019‐nCoV, since skin is the first line of defense of human body(4). It is of prime importance to ensure and maintain the skin clean, sterilized and protected of clinical health care staff during the fight against the epidemic. Self‐protection of the medical staff is essential, however, utilizing protective equipment such as goggles, masks and protective clothing continuously impairs skin integrity and the skin damage caused by the respective protective measures must be taken seriously.

Keeping the integrity of skin barrier is a critical method to prevent the spread of 2019-nCoV, since skin is the first line of defense of human body (4) . It is of prime importance to ensure and maintain the skin clean, sterilized and protected of clinical health care staff during the fight against the epidemic. Self-protection of the medical staff is essential, however, utilizing protective equipment such as goggles, masks and protective clothing continuously impairs skin integrity and the skin damage caused by the respective protective measures must be taken seriously.

To investigate the skin conditions of the front-line medical staff during the outbreak of 2019-nCoV, and identify any correlations between skin injury and the protection. We created an online questionnaire survey on skin problems in 484 clinical frontline medical staff in China during the period of 2019-nCoV and the results are as follows.

Among the 484 participants, half of them was from Wuhan and half was from the other 11 provinces of China. Female workers accounted for more than three quarters of the total (75.8%), the rest were males. The age distribution of the medical staff divided into four groups. (Fig.1A) .

The department of the medical staff was shown in Fig.1B . The protection level of the participants was divided into three levels. 18.2%, 64.1% and 17.2% of participants were equipped with biosafety level 1, 2 or 3, respectively (Fig.1C ). More than half of the participants wore the protective suit between 4-6 hours at a time and 9.1% of them kept the suit on for longer than 6 hours ( Fig.1D ). 64.2% of the staff worked 3-5 days a week, 12.4% of the staff worked more than 5 days a week, and 11.8% worked 1-2 days a week (Fig.1E)

Our correlation analysis showed that medical staff with level 2＆3 protection were more likely to experience itching than those using primary protection (p=0.0121). More advanced protection (p=0.0016), higher working frequency (p ＜ 0.001) and longer wearing times of protective suits (p=0.0016) were more correlated with the appearance of facial skin lesions (p=0.0006). The occurrence of erythema is related to protection level (p=0.0021), working frequency (p＜0.001) and the duration of wearing protective suit (p=0.0006) ( Table.1 ).

Based on the above findings, the occurrence of skin lesions of frontline medical staff is closely related to the level of protection, working frequency and duration of wearing protective suits.

Therefore, to avoid decimation of the active workforce due to irritated skin, we recommend the implementation of effective measures to ensure the integrity of skin barrier of the frontline medical staff, what's more the dermatologist's intervention is necessary.

Finally, level 3 protection was defined as the same combination as in level 2 but with addition of face mask, or a medical mask, goggles or face mask to a full set or with electric air filter respirator). Fig.1D Duration of using the protective suits. More than half of the participants wearing the protective suit between 4-6 hours per time and 9.1% of them wearing the suit over 6 hours.

Fig.1G Type of the lesions. 73.1% of the participants suffered from different type of lesions. The lesions manifested as erythema (38.8%), scratch (22.9%), blister (13.8%), rahagades (13.6%), papule/edema (12.8%), exudation/crust (6.8%) and lichenification(5.6%).
