In March 2020, Dr. Lai Hsien-yung, a Taiwanese doctor, devised an aerosol box to minimize risk of infection to health care personnel during high aerosol generating procedures like intubation. It consists of a transparent plastic box, with an opening on one side to fit over the patient's chest and 2 holes on the opposite side through which physicians can fit their hands. 4 The efficacy of this aerosol box was later tested on mannequins with simulated cough reflex. 5 Currently, many modifications of the original aerosol box have been proposed for application in other fields like dentistry and otorhinolaryngology. 6 Dermatology is another speciality where the physicians have a high risk of exposure to the virus while examining and operating on lesions on the face.

Hence, the authors propose a modified design of this aerosol box to assist in performing dermatological procedures on the face like electrocautery, microneedling with a dermapen/dermaroller, chemical peels and lobuloplasty, amongst others. This modified aerosol box ( Figure 1) consists of:

• A narrower base on the head end, so as to be accommodated on a procedure chair, which gradually widens by 10cm towards the foot end, to accommodate the shoulders of patients.

• In addition to the two circular working ports on the back surface at the doctor's end, this modified aerosol box also has two more working ports on each of the other two surfaces.

This facilitates access of the patient's face from all directions during a procedure.

• Height of the box is 50cm, with extra 5cm length of the frame projecting downwards from the base U-plate. This provides stability to the box and prevents it from sliding down from an inclined chair.

The box can be easily disinfected using 0.5% hypochlorite solution or 70% alcohol and reused for multiple patients on the same day. The authors acknowledge that this aerosol box, just like any other device, is not 100% protective or fail proof. It has been proposed to aid in providing protection to the dermatologist, in case the patient inadvertently sneezes/coughs suddenly during a procedure.

Currently, dermatologists are faced with a moral dilemma of whether to continue their practice or not. Most clinics are offering consultations only for emergency cases, while the routine cases are advised to follow up through tele-consultations. 7 While this can be followed for a short time, until we tide over the acute crisis of COVID-19, it is not practical in the long run.

Dermatological procedures cannot be postponed indefinitely. At the same time, we cannot restart our practice the same way as before the COVID era. We need to restructure our work environment to adapt to the current scenario. 8, 9 At present there is no specific treatment or vaccine for COVID-19 which can help to eradicate the infection in the near future. We need to prepare to resume our daily lives, despite the prevalence of the infection. WHO recommends using COVID-19 rapid tests only in research setting and not in clinics, as they were found to lack both sensitivity as well as specificity. 10 Hence, we propose the use of this aerosol box, as a precautionary measure, to minimize spread of infection to the maximum possible extent.
