please tell me the carriers of covid 19
Answers
Answer:
The novel coronavirus is rapidly spreading globally and has put the entire planet on standby. Despite following strict measures of hand washing and social distancing, the SARS-CoV-2 virus causing COVID-19 has been impossible to contain. Nearly 80% of people infected by coronavirus will develop mild to moderate respiratory illness which will usually recover without any treatment. However, this disease can cause serious complications in elderly people and people with underlying medical problems such as cardiovascular disease, diabetes, respiratory diseases, and cancer.
With time, we are learning more about the virus as it continues to evolve. Earlier it was thought that only people showing symptoms such as cough, high fever, or breathing difficulty was possibly infected by SARS-CoV-2 and could spread the disease through contact. But this has been proved wrong by recent studies. Even people showing no symptoms may spread the virus through contact transmission. Hence, while we have to maintain a safe distance from people showing flu-like symptoms, we also have to be aware of asymptomatic carriers who can spread the disease.
Classifying people based on the severity of the disease symptoms
Classifying people based on their symptoms is not an exact science. You may not fit anyone classification exactly or may shift from mild to moderate symptoms or vice-versa during the course of illness. With so many people that are affected, everyone may not fit perfectly into the simple groups of classification. If your symptoms are predominantly mild, with one or two moderate symptoms, you may be classified as one with mild to moderate symptoms. People with COVID-19 are classified broadly as follows:
Silent carriers
Patients with mild to moderate symptoms
Patients with moderate to severe symptoms
Critically ill patients with multi-organ dysfunction
Who is a silent carrier?
There is recent evidence that COVID-19 can spread through silent carriers. These silent carriers or spreaders are people who are infected with coronavirus but show little or no symptoms of the disease. As a result, these people carry on with their daily lives, meeting family and friends, going to work, and spreading the disease without their own knowledge. It appears that most asymptomatic carriers are healthy young adults and children. If you come to contact with people who are positive for COVID-19, you may be positive despite not showing any symptoms of the disease.
Types of Silent Carriers
The terms that are used to classify the silent carriers are:
Mildly symptomatic carriers
People who display very mild symptoms like a mild cough or may just be feeling a little low come in this category. The virus mainly affects the upper respiratory tract and may cause mild cough or mild breathlessness on exertion. Your fever may not reach 37.8℃. You may lose your sense of smell, have mild headaches, or develop a runny nose. These symptoms usually last for seven to ten days. It has been seen that some people showing mild symptoms can rapidly deteriorate, more often among people in the high-risk group.
Pre-symptomatic carriers
Some people do not develop any symptoms for up to a week after contracting the disease. They may later on experience cough, fever, or breathing difficulty.
Asymptomatic carriers
These are people who do not show any signs or symptoms of the disease on contracting it for the entire duration of the incubation period. This can last for around 14 days. As a result, they end up transmitting the virus to a lot of people. This fuels the pandemic in a rapid and dangerous manner.
Unusual symptoms to look out for
Some people may develop symptoms that are not typical to COVID-19. These include symptoms such as loss of smell, loss of taste, and diarrhea. This means that some of the people placed in the category of asymptomatic carriers could be shifted to the mildly symptomatic category keeping these symptoms in mind. Until these symptoms have been categorized, it is best to follow strict personal hygiene practices and Government protocols for quarantine and
