Causes

 Acute respiratory syndrome coronavirus 2 or SARS-CoV-2 infection causes coronavirus disease 2019 (COVID-19). Virus agent

 COVID-19 spreads easily among people. According to the data, the Covid-19 virus spreads from person to person, mainly among people who are in close contact (within about 6 feet or 2 meters). The virus is spread through respiratory droplets when a person carrying the virus coughs, sneezes, breathes, sings or talks. These droplets can be inhaled or enter the mouth, nose, or eyes of nearby people. particle for the direct object

 The Covid-19 virus can spread when a person is exposed to very small droplets or aerosols that float in the air for minutes or hours. This is known as air diffusion.

 Touching a surface on which the virus is attached and then touching the mouth, nose, or eyes can spread the virus. But the risk is small. particle for the direct object

 The covid-19 virus can spread to people who are infected but have no symptoms. This is called asymptomatic infection. The COVID-19 virus can also spread to people who are infected but do not yet have symptoms. This is called presymptomatic infection. It is possible to get

 COVID-19 occurs several times but is rare. In the case of

 This virus has one or more new mutations and is called the original type of virus. Currently, the CDC has identified two strains of the virus that cause COVID-19. These include the delta type (B.1.617.2) and the omicron type (B.1.1.529). The delta variant is more contagious than the previous variant and can cause more serious diseases. Omicron varieties spread more easily than other varieties, including Delta. However, Omicron appears to cause less serious illnesses. Omicron has several major (sub) derivatives such as BA.1, BA.2, and BA.3.

 Risk factors

 Risk factors for COVID-19 appear to be:

 COVID-19 (new coronavirus infection)

 The infected person coughs or sneezes

 Complications

 Most people with Covid-19 have mild to moderate symptoms, but the disease can cause serious complications and in some cases be fatal. Elderly people and people with existing medical conditions are at risk of developing this disease

Complications include:

•  Pneumonia and shortness of breath
•  Organ failure in multiple organs
•  heart problem
•  Severe lung disease in which little oxygen reaches the organs through the bloodstream (acute respiratory distress syndrome)
•  Clot
•  Acute kidney injury
•  Additional viral and bacterial infections

 Long-term effects of COVID-19

 Prevention

 The U.S. Food and Drug Administration (FDA) has granted emergency use authorization for some COVID-19 vaccines in the United States. The FDA has approved Pfizer-BioNTech's COVID-19 vaccine, now called Comirnaty, to prevent COVID-19 in people over 16 years of age. 15 years. The FDA has approved Moderna's vaccine, now called Spikevax, to prevent Covid-19 in people over 18 years of age. The FDA has also approved Moderna's Covid-19 vaccine for children 6 months to 17 years of age.

Due to the risk of potentially life-threatening blood clotting problems, the FDA restricts the use of the Janssen/Johnson & Johnson vaccine to certain individuals over 18 years of age. Examples include people who have had a severe allergic reaction after receiving a COVID-19 mRNA vaccine or who cannot be vaccinated with a COVID-19 mRNA vaccine due to limited access or personal or religious concerns. will be. Be sure to understand the risks and symptoms of blood clotting problems when getting this vaccine. particle for the direct object

 Vaccines can prevent you from becoming seriously ill if you have or have been infected with the Covid-19 virus. In addition, the COVID-19 vaccination may provide better protection against COVID-19 infection. Recent studies show that unvaccinated people who have previously been infected with Covid-19 are more than twice as likely to get reinfected with Covid-19 than fully vaccinated people. back

 Vaccination can safely return to many activities that may not have been possible due to the pandemic. However, if you're in an area with a high number of people hospitalized for Covid-19 and new cases of Covid-19, the CDC recommends wearing a mask in public. 2 weeks after the second vaccination with the mRNA vaccine COVID-19 or 2 weeks after the first vaccination with the Jansen / Johnson & Johnson COVID-19 vaccine is considered fully vaccinated. All recommended Covid-19 vaccines are considered up-to-date, including booster immunizations if eligible.
