Since the first quarter of 2020, there has been a worldwide impact from the COVID-19 pandemic. The World Health Organization ("WHO") declared a global emergency on January 30, 2020 with respect to the outbreak, and several countries have initiated travel restrictions, closed borders and given social distancing directives, including instructions requiring "shelter-in-place." These measures by government authorities may remain in place for a significant period of time and they are likely to continue to adversely affect the ability of our employees to visit and qualify new production suppliers, may make it such that we are unable to obtain sufficient components or raw materials and component parts on a timely basis or at a cost-effective price or may significantly hamper our products from moving through the supply chain. Our global business could be adversely affected by risks associated with public health crises and epidemics/pandemics, such as COVID-19. We rely on our production facilities, as well as third-party suppliers, in the United States, Europe and Asia, which have been significantly impacted by COVID-19. This outbreak has resulted in the extended shutdown of certain businesses in many of these countries, which may result in disruptions or delays to our supply chain and significant disruptions to our customer base. Any disruption in these businesses will likely impact our sales and operating results. The impact of COVID-19, including changes in consumer and business behavior, pandemic fears and market downturns, and restrictions on business and individual activities, has created significant volatility in the global economy and led to reduced economic activity. Even after the COVID-19 pandemic has subsided, we may continue to experience an adverse impact to our business as a result of its global economic impact, including any recession that has occurred or may occur in the future.
We implemented precautionary measures intended to help minimize the risk of the virus to our employees including temporarily requiring some employees to work remotely and implementing social distancing protocol for all work conducted onsite. We continue to limit non-essential travel worldwide for our employees. Business disruptions elsewhere in the world could also negatively affect the sources and availability of components and materials that are essential to the operation of our business in the United States, Europe, and Asia. In 2021, COVID-19 had an adverse impact on our operations, supply chains and distribution systems, and it has resulted in our sustaining higher costs on raw materials than we had previously expected. However, many regions, particularly the Southern California region where our operations are principally located, have from time to time experienced increases in COVID-19 cases and governmental authorities have responded by implementing temporary closures, lockdowns and restrictions to combat COVID-19. These increases in COVID-19 cases and restrictions may have negative impacts on our operations, including our product development timelines, supply chains and distribution systems in 2022 and beyond. In addition, our efforts to qualify new suppliers, particularly in Asia, have been postponed indefinitely, which delay has required us to continue using higher cost components for our products. Because of travel restrictions, we are not able to visit many prospective customers in person, which could delay the sales conversion cycle. Due to these precautionary measures and resulting global economic impacts, we may experience significant and unpredictable reductions in demand for certain of our products.
Despite progress in vaccination efforts, global economic activity remains uncertain and cannot be predicted with confidence. Further, in the first half of 2021, a new Delta variant of COVID-19 began to spread globally and caused an increase in COVID-19 cases in many places in the United States, and in November 2021, a new Omicron variant, which appears to be the most transmissible variant to date, was detected, which Omicron variant has since caused an increase in COVID-19 cases in multiple countries, including the United States, and of which the potential severity is currently being evaluated. Public health officials and medical professionals have warned that COVID-19 cases may continue to spike due to the Delta variant and/or the Omicron variant, particularly if vaccination rates do not quickly increase or if additional, potent disease variants emerge. It is unclear how long the resurgence due to Delta or the resurgence due to Omicron will last, how severe the Delta resurgence or Omicron resurgence will be, and what safety measures governments will impose in response to the Delta resurgence or Omicron resurgence. The impact of the Delta variant and the Omicron variant cannot be predicted at this time, and could depend on numerous factors, including vaccination rates among the population, the effectiveness of COVID-19 vaccines against the Delta variant and the Omicron variant and the response by governmental bodies and regulators. The outbreak has and may continue to affect the Company's operations and those of third parties on which the Company relies. The degree and duration of COVID-19's impact on our business, our operations, and the global economy as a whole, are unknown at this time. However, the effects could have a material impact on our results of operations, and we will continue to monitor the situation closely.
