India’s Covid-19 cases hits 280,000

India’s confirmed cases of Covid-19 reached 280,000 on Wednesday – almost a third of that total was recorded during the first 10 days of June. On a more positive note, the daily number of people who have recovered from the virus, has exceeded the number of active cases for the first time.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).It was first identified in December 2019 in WuhanChina, and has resulted in an ongoing pandemic.The first case may be traced back to 17 November 2019. As of 10 June 2020, more than 7.24 million cases have been reported across 188 countries and territories, resulting in more than 411,000 deaths. More than 3.37 million people have recovered.[Common symptoms include fevercoughfatigueshortness of breath, and loss of smell and taste.While the majority of cases result in mild symptoms, some progress to acute respiratory distress syndrome (ARDS) likely precipitated by a cytokine stormmulti-organ failureseptic shock, and blood clots. The time from exposure to onset of symptoms is typically around five days, but may range from two to fourteen days.The virus is primarily spread between people during close contact, most often via small droplets produced by coughing, sneezing, and talking. The droplets usually fall to the ground or onto surfaces rather than travelling through air over long distances. Less commonly, people may become infected by touching a contaminated surface and then touching their face. It is most contagious during the first three days after the onset of symptoms, although spread is possible before symptoms appear, and from people who do not show symptoms. The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab.Chest CT imaging may also be helpful for diagnosis in individuals where there is a high suspicion of infection based on symptoms and risk factors; however, guidelines do not recommend using CT imaging for routine screeningRecommended measures to prevent infection include frequent hand washingmaintaining physical distance from others (especially from those with symptoms), quarantine (especially for those with symptoms), covering coughs, and keeping unwashed hands away from the face. The use of cloth face coverings such as a scarf or a bandana is recommended in public settings to minimise the risk of transmissions, with some authorities requiring their use. Medical grade facemasks such as N95 masks should only be used by healthcare workers, first responders and those who care for infected individuals.

According to the World Health Organization (WHO), there are no vaccines nor specific antiviral treatments for COVID-19. Management involves the treatment of symptomssupportive careisolation, and experimental measures.The World Health Organization (WHO) declared the COVID‑19 outbreak a public health emergency of international concern (PHEIC) on 30 January 2020 and a pandemic on 11 March 2020. Local transmission of the disease has occurred in most countries across all six WHO region

Signs and symptoms

Fever is the most common symptom, but it is highly variable in severity and presentation, with some older, immunocompromised, or critically ill people not having fever at all. In one study, only 44% of people had fever when they presented to the hospital, while 89% went on to develop fever at some point during their hospitalization. A lack of fever does not verify someone is disease free.
Other common symptoms include coughloss of appetitefatigueshortness of breathsputum production, and muscle and joint pains. Symptoms such as nauseavomiting, and diarrhoea have been observed in varying percentages. Less common symptoms include sneezing, runny nose, sore throat, and skin lesions. Some cases in China initially presented with only chest tightness and palpitations.A decreased sense of smell or disturbances in taste may occur .Loss of smell was a presenting symptom in 30% of confirmed cases in South Korea.
As is common with infections, there is a delay between the moment a person is first infected and the time he or she develops symptoms. This is called the incubation period. The typical incubation period for COVID‑19 is five or six days, but it can range from one to fourteen days with approximately ten percent of cases taking longer
An early key to the diagnosis is the tempo of the illness. Early symptoms may include a wide variety of symptoms but infrequently involves shortness of breath. Shortness of breath usually develops several days after initial symptoms. Shortness of breath that begins immediately along with fever and cough is more likely to be anxiety than COVID-19. The most critical days of illness tend to be those following the development of shortness of breath.
A minority of cases do not develop noticeable symptoms at any point in time. These asymptomatic carriers tend not to get tested, and their role in transmission is not yet fully known. Preliminary evidence suggested they may contribute to the spread of the disease. In June 2020, a spokeswoman of WHO said that asymptomatic transmission appears to be “rare,” but the evidence for the claim was not released. The next day, WHO clarified that they had intended a narrow definition of “asymptomatic” that did not include pre-symptomatic or paucisymptomatic (weak symptoms) transmission and that up to 41% of transmission may be asymptomatic. The current understanding is that transmission without symptoms does occur.

Complications

may include pneumoniaacute respiratory distress syndrome (ARDS), multi-organ failureseptic shock, and death.[10][14][58][59] Cardiovascular complications may include heart failurearrhythmiasheart inflammation, and blood clots.[60] Approximately 20-30% of people who present with COVID‑19 have elevated liver enzymes reflecting liver injury.[61][62] Neurologic manifestations include seizurestrokeencephalitis, and Guillain–Barré syndrome (which includes loss of motor functions).[63] Following the infection, children may develop paediatric multisystem inflammatory syndrome, which has symptoms similar to Kawasaki disease, which can be fatal.
