When covid-19 started?

Covid-19 is a desease and was first detected in Wuhan, China, in late 2019 and has set off a global pandemic.

• Fever or chills
• A dry cough and shortness of breath
• Feeling very tired
• Muscle or body aches
• Headache
• A loss of taste or smell
• Sore throat
• Congestion or runny nose
• Nausea or vomiting
• Diarrhea

In more severe cases, infection can cause pneumonia, respiratory failure, septic shock, and death.

How long is the incubation period for COVID-19?

The estimated incubation period is between 2 and 14 days, with a median of 5 days. It is important to note that some people become infected and do not have any symptoms or feel bad.

How long does it take for symptoms of the coronavirus disease to appear?

On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.

Why covid-19 pneumonia is more deadly?

As COVID-19 pneumonia slowly moves through the lungs, it leaves damaged lung tissue in its wake and contributes to the fever, low blood pressure and organ damage common in COVID-19 patients.

The long duration of COVID-19 pneumonia, rather than greater severity, may be why it causes more serious complications than other types of pneumonia.

Why covid-19 vaccine is important?

The COVID-19 vaccines produce protection against the disease, as a result of developing an immune response to the SARSCov-2 virus. Developing immunity through vaccination means there is a reduced risk of developing the illness and its consequences. This immunity helps to fight the virus if exposed.

Which covid-19 vaccine is the best? 

There are more vaccine candidates simultaneously in the pipeline for COVID-19 than ever before for an infectious disease. All of them are trying to achieve the same thing – immunity to the virus, and some might also be able to stop transmission. 

The evidence is overwhelming that no matter which one you take, the vaccines offer life-saving protection against a disease that has killed millions.

What Covid vaccines are accepted in USA?

The Pfizer BioNTech, Moderna, and Janssen also called Johnson & Johnson (J&J) COVID-19 vaccines are FDA-approved for use in U.S.A. 

Additionally, the United States accept the use by international visitors of COVID-19 vaccines authorized by U.S. regulators or the World Health Organization.

What are the organs most affected by COVID‐19?

The virus can damage the lungs, heart and brain, which increases the risk of long-term health problems.

Some adults and children experience multisystem inflammatory syndrome after they have had covid-19. In this condition, some organs and tissues become severely inflamed.

Are children at lower risk of COVID-19 than adults?

There are different types of disease presentation based on the age of the person who is infected by this virus. Luckily, children and adolescents tend to have more mild disease compared to adults. Especially in the youngest children, they tend to be milder, which means they don’t have as many symptoms as adults do.

Some children may have gastrointestinal symptoms like diarrhoea or vomiting, but they tend to be milder. And even most children tend to have asymptomatic infection, which means they don’t have any symptoms at all.

COVID-19 and pregnancy

The Centers for Disease Control and Prevention lists pregnant women as a high-risk group for severe COVID-19 disease.

Symptomatic pregnant women who contract COVID-19 are at higher risk for severe disease, complications and death than non-pregnant women. Additionally, many pregnant women have medical conditions that put them at increased risk.

What are the symptoms of newborns infected with COVID-19?

Studies have reported mainly no symptoms or mild disease from COVID-19 in infected newborns, with low risk of neonatal death.

Can COVID-19 be transmitted through food?

There is no evidence that COVID-19 can be spread through contact with food. COVID-19 is generally thought to be spread from person to person. However, it’s always important to practice good hygiene when handling food to prevent any foodborne illnesses.

Will covid-19 end in 2022?

As we near the 2-year mark for the ongoing COVID-19 crisis, experts are offering predictions on how the situation might change going into 2022.

The COVID-19 Scenario Modeling Hub predicts pandemic deaths will fall below 100 per day by March 2022. 

Some scientists also believe vaccination could be the deciding factor in reduced deaths.
