basic information about covid -19
Answers
Answer:
What is coronavirus?
Coronaviruses are an extremely common cause of colds and other upper respiratory infections.
What is COVID-19?
COVID-19, short for "coronavirus disease 2019," is the official name given by the World Health Organization to the disease caused by this newly identified coronavirus.
How many people have COVID-19?
The numbers are changing rapidly.
The most up-to-date information is available from the World Health Organization, the US Centers for Disease Control and Prevention, and Johns Hopkins University.
It has spread so rapidly and to so many countries that the World Health Organization has declared it a pandemic (a term indicating that it has affected a large population, region, country, or continent).
Do adults younger than 65 who are otherwise healthy need to worry about COVID-19?
Yes, they do. Though people younger than 65 are much less likely to die from COVID-19, they can get sick enough from the disease to require hospitalization. According to a report published in the CDC's Morbidity and Mortality Weekly Report (MMWR) in late March, nearly 40% of people hospitalized for COVID-19 between mid-February and mid-March were between the ages of 20 and 54. Drilling further down by age, MMWR reported that 20% of hospitalized patients and 12% of COVID-19 patients in ICUs were between the ages of 20 and 44.
People of any age should take preventive health measures like frequent hand washing, physical distancing, and wearing a mask when going out in public, to help protect themselves and to reduce the chances of spreading the infection to others.
What are the symptoms of COVID-19?
Some people infected with the virus have no symptoms. When the virus does cause symptoms, common ones include fever, body ache, dry cough, fatigue, chills, headache, sore throat, loss of appetite, and loss of smell. In some people, COVID-19 causes more severe symptoms like high fever, severe cough, and shortness of breath, which often indicates pneumonia.
People with COVID-19 are also experiencing neurological symptoms, gastrointestinal (GI) symptoms, or both. These may occur with or without respiratory symptoms.
For example, COVID-19 affects brain function in some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, inability to taste, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.
In addition, some people have gastrointestinal (GI) symptoms, such as loss of appetite, nausea, vomiting, diarrhea, and abdominal pain or discomfort associated with COVID-19. These symptoms might start before other symptoms such as fever, body ache, and cough. The virus that causes COVID-19 has also been detected in stool, which reinforces the importance of hand washing after every visit to the bathroom and regularly disinfecting bathroom fixtures.
Explanation:
Hope it helps you out.....
The virus is common throughout the world, infecting both humans and animals. Before the emergence of the newest strain in Wuhan, Hubei province, six strains of coronavirus were known to affect humans, with four of them causing mild respiratory symptoms akin to common colds. The other two strains, SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome), are potentially lethal, having together killed about 1,600 people worldwide.
- Is the new strain discovered in Wuhan linked to SARS or MERS?
They all come from the same large family of coronaviruses, but the new strain belongs to a different subgroup. It also demonstrates marked differences in genome sequence from the SARS and MERS-related viruses and appears to be less deadly. However, scientists are cautious of possible mutations of the new strain that could raise the level of risk.
- What are the symptoms of the new strain?
Most patients experience mild symptoms including fever, fatigue, a dry cough and difficulty breathing. They can fully recover with effective treatment. In some cases, patients suffer severe respiratory failure, extremely low blood pressure and other life-threatening conditions.
- How to protect yourself against the new coronavirus?
Due to a lack of knowledge of the new strain, the World Health Organization has so far suggested general protective measures targeting other regular respiratory infections, including avoiding contact with people infected with respiratory illnesses, washing hands regularly and refraining from touching livestock or wild animals. Medical institutions should step up protection and control measures in their emergency.
