Coronavirus disease (COVID-19) is an infectious disease caused by coronavirus 2 that causes severe acute respiratory syndrome (SARS-CoV-2). It was discovered for the first time in China. COVID-19 was later labelled a pandemic by the World Health Organization on March 11, 2020, causing widespread worry. As no specific medicine or vaccine is available, more than 7.03 million people have become infected and 3.15 million people have recovered across 188 countries since November 2019. Social distancing, wearing masks, working from home, online learning, cashless payments, online marketing, and businesses are the new normal. There is also a huge change in the buying patterns of customers.

The symptoms of this disease are fever, coughing, headache, body pain, etc. The coronavirus disease 2019 (COVID-19) spread due to direct, indirect, or close contact with infected people. These spreads due to mouth or nose secretions which include saliva, respiratory, or droplet secretion [2]. The person who has close contact with infected droplets within 1 meter gets into the mouth, eyes or nose may lead to getting infected [6]. The proportion of cases tested positive due to the SAR-COV-2 virus concerning asymptomatic cases is 16%.

This virus causes the coronavirus disease 2019 (COVID-19), which spreads from person-to-person through saliva droplets or nasal discharges during coughing, sneezing, or talking by a patient. Symptoms include fever, cough, shortness of breath or difficulty in breathing.

Coronavirus disease 2019, abbreviated as ‘COVID-19' and scientifically known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), spread as an unknown virus in the late December of 2019 in Wuhan, Hubei Province, China (Ciotti et al., 2020). SARS-CoV-2 manifests itself in various ways in different people. Most people infected with the virus are treated at home without hospitalisation for mild to moderate illness. Fever, cough, fatigue, and loss of taste or smell are the most common symptoms of the disease. On the other hand, dyspnea, loss of speech or mobility, dizziness, and chest pain are among its severe symptoms. A person is infected with the virus for an average of 5–6 days before symptoms appear; however, this time can vary up to 14 days (World Health Organization, 2020a).

The major symptoms or signs of COVID-19 include fever, cough, difficulty in breathing and in severe cases, it can lead to pneumonia, kidney failure and death. COVID-19 belongs to viral specie that causes common cold. The name ‘Corona’ means ‘Crown’ which is name after the spike proteins on their surface which resemble crown as shown in Figure). Coronaviruses are zoonotic in nature and thus they can be transmitted from animals to humans. Although the exert source of the SARS-CoV-2 remains unknown for scientists but many evidences associated the virus to bats unlike SARS-CoV-1 and MERS-CoV, which are associated with Civet cat and Camels, respectively. COVID-19 can be transmitted through an infected person respiratory secretion such as cough or sneeze, physical contact with infected person or direct contact with surfaces that are contaminated with the virus (Park et al., 2020; Word Health Organization Report on Coronavirus disease, 22020; Chen N et al., 2020)

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is spread primarily by aerosols and droplets of respiratory fluids that are expelled by infected people when they cough, breathe, talk, sing and sneeze (Adenaiye et al. 2022; CDC 2022; Klompas et al. 2021; Tellier 2022; Wang et al. 2021). To reduce the transmission of SARS-CoV-2, public health agencies have recommended a variety of non-pharmaceutical interventions, including increased ventilation and air filtration, physical distancing, limiting occupancy of indoor spaces, and the universal wearing of well-fitting face masks, respirators, or other types of face coverings (called universal masking) (CDC 2021b; WHO 2022). Masks and other face coverings reduce the spread of infectious respiratory diseases primarily by reducing the amount of aerosols and droplets that are expelled by the wearer into the environment (called source control) (CDC 2021a). Masks also provide some personal protection to the wearer, although respiratory protective devices such as N95 filtering facepiece respirators are far more effective (Lawrence et al. 2006; Oberg and Brosseau 2008; Pan et al. 2021).
