    Coronaviruse:-

Coronaviruses are a group of enveloped viruses with no segmented, single-stranded, and positive-sense RNA genomes. Corona virus emerged in Wuhan, China, at the end of 2019. As in the start of 2020,   several cases  had  been  diagnosed  in  nine countries:  China,  Thailand,  Japan,  South  Korea, Singapore,  Vietnam,  Taiwan,  Nepal,  and  the  United States.

Introduction:

The novel coronavirus (2019-nCOV)or the severe acute respiratory syndrome corona virus 2(SARS_oV_2).On December 31, 2019, the China Health Authority alerted the World Health Organization (WHO) to several cases of pneumonia  in Wuhan City in Hubei Province in central China. The cases had been reported since December 8, 2019, and many patients worked at or lived around the local Huanan Seafood Wholesale Market although other early cases had no exposure to this market. On January 7, a novel coronavirus, originally abbreviated as 2019-nCoV by WHO, was identified And until now 400,000 deaths have occurred, mainly in patients who had serious illness. Although the information about the emergence of this virus such as its origin and its abilit spread among humans   remain unknown, an increasing number of cases appear to have resulted from human-to-human transmission. World Health organization (WHO) has ordered countries to take it seriously and has declared this as worldwide pandemic and declare Health Emergency so that the growth of this virus can be minimized.

Types:

229E (alpha Coronavirus)

NL63 (alpha Coronavirus)

Death rate:-

Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable.

Transmission:

Data from published epidemiology and virology studies provide evidence that COVID-19 is primarily transmitted from symptomatic people to others who are in close contact through respiratory droplets, by direct contact with infected persons, or by contact with contaminated objects and surfaces.

•Person to Person

When an infected person cough, sneeze or talks, droplets with virus fly into the air from their nose or mouth. Droplets of coronavirus can enter into the lungs from 6 feet distance. 

Cough is the main source of Covid19 transmission because a person having covid19 coughs that transmittal the spot and by this way virus goes from person to person.

•people aged above 65

It is observe that coronavirus was dangerous for aged people because of their weak immune system.

•Children’s:

Covid19 is also very dangerous for children because their immune system is very weak and they can't fight with diseases the way a teenager can fight.

Prevention:

• Clean your hands often. Use soap and water, or an alcohol-based hand sanitizer

• Maintain a safe distance from anyone who is coughing or sneezing.

• Don’t touch your eyes, nose or mouth.

• Cover your nose and mouth with your hand or a tissue when you cough or sneeze.

• Stay home if you feel unwell.

• If you have a fever, cough and difficulty breathing, seek medical attention.

Testing:

Ppatient suspecting symptoms of coronavirus should visit a government designated public or private hospital. They see are equipped to collect samples for coronavirus.

Diagnose:

• Those requiring admission to hospital 

• who have either clinical or radiological evidence of pneumonia

• Acute respiratory distress syndrome

• Influenza like illness (fever ≥37.8°C) and at least one of the following respiratory symptoms, which must be of acute onset: persistent cough [with or without sputum], hoarseness, nasal discharge or congestion, shortness of breath, sore throat, wheezing, sneezing)

A loss of, or change in, normal sense of taste or smell (anosmia) in isolation or in combination with any other symptoms.

Covid19 worldwide:

Coronavirus is getting worse day by day. There is economical destroy because of lockdown and health emergency. In start research shows that covid19 getting worse in highly populated countries bit as the time we find that there is no any truth in this statement. The countries that are highly effected by Covid19 are.

Coronavirus Cases:                         Recovered:

 7,113,156                                          3,472,126 

Deaths:

406,549

Treatment:

Scientist and biological experts uses the plasma therapy for the cure of Covid19 disease till the vaccine produce by pharmaceuticals. Plasma.

In the search for an effective treatment for COVID-19, an old method of fighting infectious diseases has recently resurfaced: transfusions with convalescent plasma. Plasma is a component of blood.

This is a simple method. The blood of people who have recovered from an infection contains antibodies. Antibodies are molecules that have learned to recognize and fight the pathogens, such as viruses, that have caused disease.

Doctors can separate plasma, one of the blood components that contain such antibodies, and administer it to people whose bodies are currently fighting an infectious disease

Conclusion:-

Diseases do not, indeed, know borders. This is now more vital to understand and recognize than ever. Millions of people are

 searching for answers, treatments, improvements and care in their daily lives. Aren’t we, during “normal circumstances”, 

Advice for covid19 patient:-

Patients have been advised not to go to their community pharmacy if they are concerned that they have COVID-19. Those with a new, continuous cough or a high temperature or too, rapidly approaching what can only be described as a state of emergency when it comes to no communicable diseases, with the brain leading as the highest cause of ill-health and disability worldwide? Could we, too, easily have a no communicable pandemic brewing around us

• Benefit of lockdown:

• Clearer water of all the river including in Venice.

• Reduction in pollution due to not use of vehicular traffic.

• Reduction of carbon emissions.

• No dust in the air due to construction sites

• Low level of carbon dioxide

• Blues skies all over the world
