Everything to know about COVID 19

 History and Introduction:

Corona virus disease (COVID-19) is an infectious disease caused by a newly discovered corona virus.The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or exhales. These droplets are too heavy to hang in the air, and quickly fall on floors or surfaces.You can be infected by breathing in the virus if you are within close proximity of someone who has COVID-19, or by touching a contaminated surface and then your eyes, nose or mouth.

                                                                                                                                                

Origin of COVID 19:

You can be infected by breathing in the virus if you are within close proximity of someone who has COVID-19, or by touching a contaminated surface and then your eyes, nose or mouth.The virus shows little genetic diversity, indicating that the spillover event introducing SARS-CoV-2 to humans is likely to have occurred in late 2019. Epidemiological studies estimate each infection results in 1.4 to 3.9 new ones when no members of the community are immune and no preventive measures taken.

                                  All SARS-CoV-2 isolated from humans to date are closely related genetically to corona-viruses isolated from bat populations, specifically, bats from the genus Rhinolophus. Bats in the Rhinolophus genus are found across Asia, Africa, the Middle East, and Europe. SARS-CoV-2 is not genetically related to other known coronaviruses found in farmed or domestic animals.

Symptoms:

COVID-19 affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization.

Most common symptoms:

fever

dry cough

tiredness

Less common symptoms:

aches and pains

sore throat

diarrhea

conjunctivitis

headache

loss of taste or smell

a rash on skin, or discoloration of fingers or toes

Serious symptoms:

difficulty breathing or shortness of breath

chest pain or pressure

loss of speech or movement

Seek immediate medical attention if you have serious symptoms. Always call before visiting your doctor or health facility.

People with mild symptoms who are otherwise healthy should manage their symptoms at home.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.

Treatments:

To date, there are no specific vaccines or medicines for COVID-19. Treatments are under investigation, and will be tested through clinical trials.

Self-care

#)If you feel sick you should rest, drink plenty of fluid, and eat nutritious food. Stay in a separate room from other family members, and use a dedicated bathroom if possible. Clean and disinfect frequently touched surfaces.

#)Everyone should keep a healthy lifestyle at home. Maintain a healthy diet, sleep, stay active, and make social contact with loved ones through the phone or internet. Children need extra love and attention from adults during difficult times. Keep to regular routines and schedules as much as possible.

#)It is normal to feel sad, stressed, or confused during a crisis. Talking to people you trust, such as friends and family, can help. If you feel overwhelmed, talk to a health worker or counselor.

Medicines:

While some western, traditional or home remedies may provide comfort and alleviate symptoms of mild COVID-19, there are no medicines that have been shown to prevent or cure the disease. WHO does not recommend self-medication with any medicines, including antibiotics, as a prevention or cure for COVID-19. However, there are several ongoing clinical trials of both western and traditional medicines. WHO is coordinating efforts to develop vaccines and medicines to prevent and treat COVID-19 and will continue to provide updated information as soon research results become available.
