New Study Finds Nausea, Vomiting and Appetite Loss as Early Symptoms of Coronavirus
8Why does coronavirus cause digestive symptoms?
Scientists feel that COVID-19 affects the digestive tract because SARS-CoV-2 is almost the same as SARS-CoV. It can infect the human body and bind to a human ACE-2 or angiostein converting enzyme -2 receptor. The process leads to liver injury because of the production of excess liver cells called hepatocytes the are sourced from ells in the bile duct. SARS -CoV-2 has also been found to damage the digestive tract through an inflammatory response, directly or indirectly. The subsequent chain reactions set off harm or injure the digestive system.
9Some common but valid questions being asked about COVID-19
How dangerous is the virus?
The fatality rate of the virus is 2% and similar to the Spanish Flu of 1918 that took the lives of 50 million people. There is much debate among experts who are in conflict over the statistics of the virus. Their biggest concern is whether the actual number of people infected is higher than the number of cases recorded. This is because there could be several people with mild symptoms that they don’t realise until they undergo a test. Only serious cases are being discovered they feel which is why the death toll is appearing higher than it actually is.
An investigation by a WHO official Dr. Bruce Aylward who travelled to China revealed that there were no grounds for this assumption to be true as all records and readings were accurate.
10Can the virus be cured?
COVID -19 as of now is proving difficult for scientists to contain and as a result there is no cure just yet. Antibiotics are not effective against any virus and though antivirals do work against viruses, it takes years of research and money to study the process of a virus and figure out ways to treat it and produce a drug cure. Vaccines are presently in testing stages with human trials and the coming weeks will reveal how effective they are against the virus.
11Healthy people recover with not so severe symptoms
No vaccine exists for the coronavirus yet and it’s not likely one will be developed in time to be of any use in this outbreak, for similar reasons to the above. As of now healthy people contracting the virus will recover without much issues and not much medical help either as symptoms more or less mimic the flu such as runny nose, fever, sore throat and cough. However, it is the elderly and those with underlying health conditions that are more at risk of complications from the virus such as pneumonia. Children are doing surprisingly well against the virus and that is puzzling the experts worldwide.
