Introduction

Corona virus comprises of a large family coronaviridae sub family coronavirinae of viruses that infect a large range of hosts including human beings as well animals (camels, cattle, cats, and bats).
There are four different strains of corona virus [1].
1. Alpha coronavirus- HCoV-22E and HCoV-NL63 (infect humans), Pig,Cat,dog CoVs.
2. Beta coronavirus- HCoV-OC43, HCoV-HKU1, MHV, a) HCoV-SARS (that causes severe acute respiratory syndrome, or SARS)
b) MERS-CoV(that causes Middle East Respiratory Syndrome, or MERS)
c) SARS CoV-2(novel coronavirus that causes the coronavirus disease 2019, or also known as COVID-19)
3. Gamma corona virus-Chicken and turkey CoVs
4. Delta corona virus - Bird CoVs

Sometimes corona virus from animals infects humans and spread further via human to human transmission such as with MERS-CoV, SARS-CoV, and now with this COVID 19 (Corona disease 2019). The virus that causes COVID-19 is designated as severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) previously, referred to as nCoV-2019.In December of 2019, this novel corona virus was found to be a cause of upper and lower respiratory tract infections in Wuhan, a city in the Hubei Province of China. It rapidly spread throughout China and then gradually epidemic spreading to other parts of the world in pandemic proportions. It has spread almost every continent in this world. In February 2020, the World Health Organization designated the disease COVID-19, which stands for corona virus disease 2019 [2,3].

Mode of Transmission

The virus is released along with the respiratory secretions when an infected person coughs, sneezes or talks. These droplets carrying the infection can spread infection to others if they make direct contact with the mucous membranes. Infection can also spread by touching an infected surface and followed by eyes, nose or mouth. Patients are thought to be most contagious when they show clinical symptoms of active disease. Some spread might be possible before symptoms appear, but this is not thought to be a common occurrence [4-6]. Asymptomatic carriers (also referred to as super spreaders) have been shown to spread the COVID-19. These are cases that have no symptoms and radiological manifestations but can transmit the virus to others [7]. Globally, as of 23rd july 2021, 17:11 GMT there have been 4,489,503 confirmed cases of COVID-19, 192,284,207 cases including 4,136,518 deaths, reported to WHO [8] Figure 1.

Pathophysiology of COVID-19

The Coronaviruses are a large family of single-stranded RNA viruses (+ssRNA) that can be isolated in different animal speciesSARS-CoV-2 belongs to the betaCoVs. It has a round or elliptic and often pleomorphic form, and a diameter measuring approximately 60–140 nm (Figure 2). According to recent research, this spike mutation, which probably occurred around late November 2019, triggered transmission to humans. The disease progression can be divided into below mentioned three distinct phases [9-11] (Table 1).
a) Early infection phase
b) Pulmonary phase
c) Severe hyper-inflammatory phase

Clinical Features

a) Incubation period- approximately 4 to 14 days following exposure [12,13]
b) Common clinical features at the onset of illness were [13,14].
c) Fever in 88-99 %
d) Fatigue in 38-70 %
e) Dry cough in 59-68%
f) Anorexia in 40 %
g) Myalgia in 15-35 %
h) Dyspnea in 19-31 %
i) Sputum production in 27-34 %

Laboratory Findings

Total number of peripheral white blood cells is normal or decreased, the lymphocyte count is reduced, and some children have increased liver enzymes, lactate dehydrogenase (LDH), muscle enzymes, and myoglobin some critically ill patients have increased troponin, D-dimer and ferritin and the number of peripheral blood lymphocytes have progressively decreased.

Radiology

The most important finding in early stages is a single or multiple limited ground-glass opacity which is most commonly located under the pleura or near the blood vessel of the bronchus especially in the lower lobes. Severe period is very rare, manifested by diffuse unilateral or bilateral consolidation of lungs and a mixed presence of ground glass opacities [15]. Consolidation with surrounding halo seen in pediatric patients and was suggested as a typical sign in pediatric patients [16] (Figures 3 & 4).

Impact of COVID 19 Pandemic on Delivery of Surgical Care

The pandemic of COVID-19 caused by the coronavirus SARSCoV- 2 is disrupting global health, social welfare and the economy in a proportion unparalleled in modern history [17]. In addition to the effects of the COVID 19 pandemic itself on public health, a collateral effect from panuniversal disruption and cancellation of operative interventions has emerged. The current pandemic has unprecedented implications for surgical services and patients with surgical conditions [18]. Surgical capacity may experience extreme challenges in pandemic zones [19,20]. The ability of surgical services to play a key role depends on the development of the peak of the pandemic, the spread of the infection and disease, the duration of societal regulations and implementation of societal laws, and the duration and temporal epidemic cycle repeats by which the disease burden will approach the threshold of maximum capacity of the critical care resources [21] (Figure 5).

Number of surgeries being put on a pause and how this burden will be addressed in the fallout of the pandemic. Rough estimates suggest that approximately 330 million operations are done worldwide annually [22]. The vast majority in high-income countries now following a strong policy of deferring of all nonemergency surgeries (North America and European countries).
With a global average of about six million a per week, the total numbers of patients who will be affected over the coming months are growing rapidly .In the current pandemic, patients may prefer to have elective surgery deferred due to fear of contracting the disease during the hospital stay .However, this fear also leads to patients not seeking timely care for conditions that would otherwise have been correctable or curable by presenting at an earlier stage; loss of function, reduced life expectancy and chronic debility may be the result of delayed presentation and hence an untimely diagnosis. This burden will only increase with the duration and severity of the pandemic. When the destructive effects of natural or man-made forces overwhelm the ability of a given area or community to meet the demand for healthcare [23].
Trauma admissions still occur during a pandemic, although there are unconfirmed reports of a reduction in acute and trauma admissions due to social distancing and overall reduced activity in society. Although trauma admissions may drop, so may the recruitment of the regular bunch of blood donors, potentially leading to a shortage of blood products in many systems. In addition, coagulation may be affected in patients who are COVID- 19-positive, potentially adding to issues with bleeding injuries [24]. Patients who were admitted for an acute abdomen or any pathology requiring acute surgery may be co-infected with COVID-19, and hence represent a risk for infecting the healthcare personnel and other patients, even when asymptomatic or experiencing severe symptoms suggestive of COVID-19. One of the main concerns is the ability asymptomatic patients may have to infect during the incubation period [25].
Pandemic effects on organ transplantation is related to its impact on the donor pool and the risk of transmission of infection, risk to healthy living donors and overall access to scarce resources [26,27]. The scenario of exposing a healthy donor to a major surgical procedure in concordance with the risk of being infected with COVID-19 must be considered and calls for caution, even if cases of successful recovery exist [28]. As the overall strain of the pandemic intensifies, this might dynamically change organ allocation and prioritization of policies [26,27].

Material and Methods

The information and statistical data is collected from various international journals published worldwide and electronic media.

Results

Impacts of COVID pandemic on surgical services are profound potentially long-lasting and extensive. Due to the cancellation of surgeries, there is drastic effect not only on wellbeing of the patient but also on emotional, psychological and physical health. Surgeries which was planned in pre COVID week are cancellation after lockdown because of that patients can experience feelings of sadness, disappointment, anger, frustration and stress [29]. This superimposes on the potential economic consequence (loss of jobs, sick leaves or reduction in work availability) and impact on family life. A complete neglect of certain surgical services can be considered unwelcome collateral damage, and unwittingly increase the number of deaths and life-years lost where the onus lies on the COVID-19 pandemic. This can create ethical dilemmas at a time of scarce resources and high pressure, burnout, guilt and unbearable psychological pressure on health care workers. As elective surgery has been cancelled on a scale never seen before in history of modern medicine, the collateral damage to health and well-being, maintenance of functionality, and risk of shortened lifespan is present for patients in countries of all income and development statuses. With a long-lasting lockdown and social distancing in effect, there will be millions of operations cancelled, postponed or simply not done at all over the times to come. The cancellation of all elective operations creates a huge backlog of patients who have been, or would be, seen for planned surgery (Figure 6).
The effects of COVID-19 on surgical outcomes (and vice versa) are not known. Pathological changes in blood coagulation [30], inflammatory response [31], and co-morbidities added to single or multiple organ failures, [32] may be considered as mechanisms for added risk for surgery. Blood and blood products reserves could be affected to a great extent as blood donations decrease due to decrease in frequent (regular) blood donors, potentially leading to as shortage of blood and blood products in some systems. In addition, coagulation system may be deranged in patients who are COVID-19-positive, potentially adding to issue in patients undergoing major surgeries requiring blood transfusion and traumatic bleeding injuries. Limiting access to transplantation is associated with a significant fall in prognosis for most patients on the transplant list, there is decreased donor pool, risk of transmission of COVID infection to the healthy donor. Lung transplant recipient have risk of getting infection via infected lungs. One of the main concerns is the ability asymptomatic patients may have to infect during the incubation period [33], and if large number of senior surgeons is exposed to infected patients, the possibility for them to become infected and requiring self-isolation is real and could potentially result in a dangerous shortage of senior expertise within surgical teams. The competition for scarce resources related to hospital, ICU beds, health care workers, PPE and blood transfusions mandates strict prioritization in several surgical disciplines, notably transplantation, cancer surgery and other highrisk procedures. As a result, some patients may unfortunately not receive the treatment they would otherwise have received. The post pandemic evaluation and future planning should involve strategies to tackle shortage and include surgical services as an essential part to maintain appropriate surgical care.

Discussion

As elective surgery has been cancelled on a scale never before seen in modern history, the collateral damage to health and wellbeing, maintenance of function, and risk of shortened lifespan is present for patients in countries of all income designation, poor and marginalized will be affected most severely. In a situation where resources are scarce, one should not treat or prioritize on a first-come, first-served principle [34]. With a long-lasting lockdown and social distancing in effect, there will be millions of operations cancelled, postponed or simply not done at all over the times to come. Surgery is already recognized as a scarce resource in much of the world [35-36]. with a global challenge to provide safe surgery and anesthesia as a recognized area of priority [37,38].
A strong advocacy agenda is needed that includes investigation, planning research and communication for surgical services for future pandemics. Surgical delivery before, during and after a pandemic, owing to its cross-cutting nature and synergistic effects on health systems at large needs to be addressed into the WHO agenda for national health and planning. In this pandemic situation mindful utilization of financial and human resources is very important. Judicious utilization of resources and manpower is of utmost importance in healthcare. It is important to ensure the ability of surgeons, so we need to change the policies in the country like construct surgical systems in terms of infrastructure, workforce, care delivery, information management, financing and governance so that we can combat the damage caused by this pandemic. To inform COVID-19 surgical plans and address patients’ concerns effectively, there is an urgent need for high-quality multi center research. Data on the effects of surgical cancellation on patients’ complete well-being, including emotional and physical health, are much required. In addition, the effect of the stacking up of operations and the fallout of the pandemic will need to be analyzed. Guidance is urgently needed on how to deliver surgical services safely and effectively in the face of pressures placed by the COVID-19 pandemic [17-19].

Conclusion

Surgical services need a contingency plan for maintaining surgical care in an ongoing or post pandemic phase. The current situation is unparalleled in history of modern medicine, and so no readily available information exists to compare or extrapolate the effect of disruption of surgical services and operations on public health during the global pandemic. To mount an effective response to the COVID-19 pandemic, hospitals should prepare detailed context-specific pandemic preparedness protocols and teams for surgical services and key domains for the same includes prepare a pandemic response plan for surgical services ,ensure staff are trained to deliver surgery safely during pandemic, hospital response to COVID-19,agree a team-based approach for running emergency services .Important areas for future research may include finding the impact of COVID-19 infection on postoperative outcomes, identifying risk stratification strategies, and determining whether prophylaxis using drugs for COVID (example HCQ) reduces rates of hospital-acquired COVID-19 infection. There is also a need to determine whether COVID-19 is present in abdominal fluids (urine, bile and peritoneal fluid) or aerosols created during introduction of pneumoperitoneum, in order to inform recommendations around the benefits and risks of open and laparoscopic surgery during the COVID-19 pandemic.
