2019 Novel corona virus –COVID 19 with its origin from Wuhan, Hubei province China by the end of 2019 is a rapidly evolving situation which needs better prevention. W.H.O declared it as a public health emergency of international concern on January 30, 2020.
According to some research papers published, though there have been researches conducted on the epidemiology, genetics of covid 19 in China, the researchers from other countries are not able to access it due to the language barrier. It is important to understand that whatever information is available for prevention of epidemiology has to reach the healthcare workers which will be an effective strategy to reach the public. Since the outbreak now meets with the criteria for PHEIC or public health emergency of international concern, there is a need for coordinated efforts for a better preparedness and prevention to interrupt the virus spread.
Initiatives has to be taken as per Article 44 of the IHR (2005), in supporting each other on the identification of the source of this new virus, its full potential for human-to-human transmission, preparedness for potential importation of cases, and research for developing necessary treatment.In an effort to fight against the outbreak which meets with the criteria for public health emergency of international concern,it is important to understand that interruption of covid 19 spread is to be achieved through coordinated efforts for prevention and to educate health care workers there by reaching public.
Early recognition is required for the management of this condition.
As per the reports, it is indicated that initial cases of coronavirus is epidemiologically linked to the exposure to Wuhan’s Hunan sea food marketing, where wild animals are traded. It is observed that the symptoms include lower respiratory tract illness with fever, dry cough and dyspnoea which is similar to symptoms caused by other corona viruses that is SARS and MERS. As per lancet journals on COVID-19 it is observed that imaging features of covid 19 are diverse as it ranges from normal to diffuse changes in lungs.
Tests for diagnosis includes:
- RT- PCR
- CT Scan
- Serum antibody test in asymptomatic high risk individuals.
As per the research papers published the most common patterns observed during ct is ground glass opacity, ill defined margins, smooth or irregular interlobular septal thickening, a crazy waving pattern and thickening of adjacent pleura. It is observed that abnormal lung CT findings can be present even in asymptomatic patients, and lesions can rapidly evolve into a diffuse ground-glass opacity predominance or consolidation pattern within 1–3 weeks after onset of symptoms, peaking at around 2 weeks after onset. As it is a rapidly evolving situation and still the researches are going on regarding its outbreak the effective strategies to be adopted is to educate all regarding its prevention. It includes:
- Use face masks especially when you are sick.
- Cover your cough or sneeze with a tissue and make sure you throw the tissue in the trash.
- Clean and disinfect the frequently touched objects in your house.
- Always wash hands with sanitizer if hands are visibly dirty.
- Try to avoid exposure to untidy and over crowded areas.
- Avoid close contact with sick people.
- Maintain hygiene.
- Try to take properly washed and cooked vegetables and clean healthy homely food.
It is beneficiary to understand that chances of human to human transmission is high as it is a droplet infection in which the virus can survive for few days in the infected droplets from a patient and can spread through surface contact also.
