Novel CORONA virus OUTbreak

When disease is new, there is no vaccine until one is developed.

A virus is a micro organism and is able to multiply only within the living cells of a host. Viruses are different from plants, animals, and baceria in their structure and function. Viruses Infect Plant, Animal, and Bacterial cells.

Coronaviruses are a large family of viruses with some causing less severe disease like common cold and others causing more severe disease like Middle East Respiratory Syndrome(MERS) and Severe Acute Respiratory Syndrome(SARS).

On 31 December 2019, the World Health Organisation (WHO) was informed of a cluster of cases of pneumonia of unknown causes detected in Wuhan city, Hubei province of China. On 12 January 2020, it was announced that a novel coronavirus had been identified in samples obtained from the cases. A novel coronavirus (CoV) is a new strain of coronavirus that has not been previously identified in humans. According to W H O, the interim name of the disease-causing current outbreak should be “2019-nCov acute respiratory disease”. So “2019-nCov” is the interim name of the virus -where ‘n’ is for novel and Cov is for Coronavirus.

Since the disease represents a risk outside of China, where it emerged, the W H O declared on 31.01.2020 that the new Coronavirus outbreak was a global health Emergency. The declaration serves notice to all U N member states. Countries can decide whether to close their borders, cancel flights, screen people arriving at Airports or take other measures. Investigations are on going to confirm whether the outbreak is by a Zoonotic source. If it is Zoonotic, they will transmit between animals and people. Several known coronaviruses are circulating in animals that have not yet infected humans.

The 2019- nCov has ben traced to snakes in China. Snakes often hunt for Bats in wild. Reports indicate that snakes were sold in the local seafood market in Wuhan in China, raising the possibility that the 2019-nCov might have jumped from the host species bats- to snakes and then to human at the beginning of the outbreak.

Transmission

Like other coronaviruses, the novel 2019-nCov is suspected transmitting by large respiratory droplets and direct or indirect contacts with infected secretions. At present, there is no proven antiviral treatment for coronavirus. Common signs include respiratory symptoms, fever, cough and breathing difficulties. In more severe cases infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.So many of the symptoms can be treated and hence the treatment is based on patients clinical condition.

Follow the standard precautions to reduce the transmission of illness. Maintain basic hand and respiratory hygiene, safe food practices and avoid close contact with anyone showing the symptoms.
