Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for coronavirus disease 2019 (COVID-19), which began as a few cases of a flu like disease in Wuhan, China, is now a pandemic that has affected millions of people globally and has forced upon unprecedented changes in every field of life [1]. During these times of crisis, inevitably people are expected to develop fear of the unknown and resist change, the magnitude of which has brought about population-wide psychological impact. Due to the ongoing pandemic, individuals are most likely to develop feelings of anxiety and uncertainty due to fear of contracting the virus, whereas with all the changes and adjustments to daily routines, it has also brought on financial pressures, social isolation and unhealthy habits, therefore the impact of which on individuals undergoing rehabilitation is likely to be significant [2]. During a previous influenza A H1N1v outbreak in the UK in 2009, around 10% to 30% of the general public were very or fairly worried about the possibility of contracting the virus [2]. Consequently, there has been a striking increase in cases of depression, anxiety, and substance abuse [2]. Indeed, recent researches suggest that addiction problems are likely to worsen during the lockdown instead of slowing down [3]. Importantly, the COVID-19 affected patients particularly those in isolation are likely to express stress, anxiety and depressive symptoms. Such behavior has previously been reported from SARS and MERS cases, which found that many of those patients experienced some degree of confusion (27.9%, 36 of 129 patients), depressed mood (32.6%, 42 of 129), anxiety (35.7%, 46 of 129), impaired memory (34.1%, 44 of 129), and insomnia (41.9%, 54 of 129) [4]. In a meta-analysis, the point prevalence in the post-illness stage of these cases was found to be 32.2% (95% CI 23.7–42.0%) for post-traumatic stress disorder (PTSD), 14.9% (12.1–18.2%) for depression, and 14.8% (11.1–19.4%) for anxiety [5].

Since COVID-19 pandemic has remarkably raised mental health concerns, one of the high risks and possibly neglected groups includes individuals undergoing mental health rehabilitation, the impact on which can be significant as compared to the rest of the population. This can be due to pre-existing depression and anxiety disorders in such individuals that can exacerbate in the times of crisis and shake the foundations of stability or recovery for them. To facilitate speedy and smooth recovery of such individuals during this time period, an added responsibility is placed upon rehabilitation center counselors, staff and management [6].

As social distancing is considered to be the key preventive measure for infection control, mental health rehabilitation day boarding and day care centers, being a non-emergency service have limited new admissions, cancelled programs and have been temporarily closed at some places which in turn is going to significantly deprive people with chronic mental illnesses and intellectual disabilities of these services [7]. The clinical outcome for these individuals will be adverse with a risk of aggravation of symptoms and even a relapse. Therefore, it is imperative to develop home-based rehabilitation strategies such as telepsychiatry in order to continue therapy for them [8].

Individuals with pre-existing mental health problems are generally at high risk of infections, hence they are inevitably at an increased risk of COVID-19 [9]. Some of them are of older age and on medications, and being identified as a vulnerable group can contribute to heightened anxiety [10]. For patients with psychiatric disorders, it is expected of them to exhibit irrational behavior as many have been reported to show increased stress about their physical health, anger, impulsivity, and suicidal ideation [11]. It may be difficult for people with schizophrenia and other related disorders to practice and adhere to the protective measures recommended to prevent infection such as hand washing, wearing masks [12]. Of note, it is a major challenge for individuals in rehabilitation to practice social distancing, as social interaction for them is not a luxury, but rather a form of therapy [13]. Group interactions and projects are part of their treatment where they walk the grounds, dine in communal areas, watch television together in day rooms, exercise and go to therapy together. The peer-support groups meetings and activities are such a vital source of emotional and spiritual support to people struggling to stay in recovery. Hence isolation can be dangerous and the fear of contracting a life-threatening illness is unlikely to promote psychiatric healing. The psychology of fear associated with this virus can result in elevated levels of anxiety and depression which may have a negative impact on recovery [14]. One of the major challenges faced by many individuals with underlying mental disorders and in recovery is prolonged isolation, which is likely to cause anxiety and depression that can be damaging if they are required to stay at home until the pandemic lasts. Isolation is considered as a negative notion when it comes to mental health rehabilitation, hence forcing people to isolate will likely have adverse effects on recovery [15].

In the fight against COVID-19 pandemic, there is a need to address mental health challenges and develop strategies and interventions to ensure continued quality care. Adequate measures are being taken in some countries like the USA, such as regular testing of patients and potential patients for COVID-19, adapting their programs to comply with social-distancing guidelines such as the use of telepsychiatry to limit the exposure possibility [16]. There is a shift observed from on-site facilities and group therapies to virtual or phone conferencing platforms. These strategies will be effective to mitigate spread of COVID-19 in vulnerable communities and simultaneously provide adequate care to mental health rehab patients.

One emerging consequence of COVID-19 is the presence of post-intensive care syndrome (PICS) characterized by symptoms involving physical strength deficits, cognitive decline, and mental health disturbances observed after discharge from critical care that persist for a protracted amount of time [17]. Therefore, patients surviving intensive care units (ICU) and mechanical ventilation for several weeks and other severe conditions will require early rehabilitation and other interventions. It is imperative to establish an integrated rehabilitation response for patients recovering from critical care at hospital with the help of psychologists, physical and occupational therapists etc. This issue needs additional attention in low resource countries where resources and workforce required for rehabilitation are inadequate [18].

In order to ensure that all individuals on the road to recovery and/or admitted to a rehabilitation center are not alone and forgotten during the times of coronavirus crisis they should be provided with adequate resources, such as online meetings and group therapy sessions, assessment, treatment and support by telephone and video consultation and getting the medications they need to recover.
