At the beginning of 2020, we suffered from the raging of covid-19.
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first case was identified in Wuhan, China, in December 2019. It has since spread worldwide, leading to an ongoing pandemic. Symptoms of COVID-19 are variable, but often include fever, cough, fatigue, breathing difficulties, and loss of smell and taste. Symptoms begin one to fourteen days after exposure to the virus. Around one in five infected individuals do not develop any symptoms. While most people have mild symptoms, some people develop acute respiratory distress syndrome (ARDS). ARDS can be precipitated by cytokine storms, multi-organ failure, septic shock, and blood clots. Longer-term damage to organs (in particular, the lungs and heart) has been observed. There is concern about a significant number of patients who have recovered from the acute phase of the disease but continue to experience a range of effects—known as long COVID—for months afterward. These effects include severe fatigue, memory loss, and other cognitive issues, low-grade fever, muscle weakness, and breathlessness. (Wikipedia)
So far we know the sequence of events:
In order to prevent the spread of the epidemic, governments of various countries have implemented some effective policies, including prohibiting large gatherings and wearing masks when going out. These measures have reduced the spread of the virus to a certain extent, but have also caused a lot of economic impacts, especially in the aviation industry. From the data point of view, the decline is very obvious from previous years.
And as of now, covid-19 still surrounds us
This had to cause the World Bank to re-evaluate its expectations for future economic growth. Although it lowered its expectations, it was still optimistic.
COVID-19 not only affects us economically but also affects us in life, especially mental health.
Mental health can have an invisible impact on our body, so we must learn to adjust our emotions during the epidemic.
Although the dark cloud of covid-19 still looms over us, we have already seen some hope, that is, the successful development and application of vaccines.
