Is Nepal safe from the coronavirus?
Recently the outbreak of the coronavirus has brought disaster throughout the world. People all over the world are afraid due to this virus. The coronavirus was first identified in Wuhan, a city in Eastern China, however, now the effect of the virus can be seen all over the world. More than 3,300 people have died globally from the COVID-19, as the illness is officially known, whereas more than 98000 infections have been confirmed in dozens of countries according to the World Health Organization.
In such a condition if you are planning to travel Nepal then there might be some questions on your mind related to the effects of the virus in Nepal. Is Nepal Trekking safe from coronavirus? Are there any chances of getting infected while traveling to Nepal? Here we will provide some information related to these questions.
Coronaviruses are a group of viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that are typically mild, such as the common cold, though rarer forms such as SARS, MERS, and COVID-19 can be lethal. Symptoms vary in other species: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to prevent or treat human coronavirus infections.
Coronaviruses were first discovered in the 1960s. The earliest ones discovered were infectious bronchitis virus in chickens and two viruses from the nasal cavities of human patients with the common cold that were subsequently named human coronavirus 229E and human coronavirus OC43. Other members of this family have since been identified, including SARS-CoV in 2003, HCoV NL63 in 2004, HKU1 in 2005, MERS-CoV in 2012, and SARS-CoV-2 (formerly known as 2019-nCoV) in 2019. Most of these have involved serious respiratory tract infections.
After entry into the host cell, the virus particle is uncoated, and its genome enters the cell cytoplasm.The coronavirus RNA genome has a 5′ methylated cap and a 3′ polyadenylated tail, which allows the RNA to attach to the host cell's ribosome for translation.Coronavirus genomes also encode a protein called RNA-dependent RNA polymerase (RdRp), which allows the viral genome to be transcribed into new RNA copies using the host cell's machinery. The RdRp is the first protein to be made; once the gene encoding the RdRp is translated, translation is stopped by a stop codon. This is known as a nested transcript. When the mRNA transcript only encodes one gene, it is monocistronic.Coronavirus non-structural proteins provide extra fidelity to replication, because they confer a proofreading function, which is lacking in RNA-dependent RNA polymerase enzymes alone.The genome is replicated and a long polyprotein is formed, where all of the proteins are attached. Coronaviruses have a non-structural protein – a protease – which is able to cleave the polyprotein. This process is a form of genetic economy, allowing the virus to encode the greatest number of genes in a small number of nucleotides.
Human to human transmission of coronaviruses is primarily thought to occur among close contacts via respiratory droplets generated by sneezing and coughing.
Symptoms of coronavirus
Common Symptoms of infections include respiratory symptoms, fever, cough, shortness of breath and difficulty in breathing. If the case is more severe then the infection can result in pneumonia, severe acute respiratory syndrome, kidney failure and even a death of a person might occur.
How to prevent yourself from CoronaVirus?
According to WHO(World Health Organization), ten preventive measure for Coronavirus are:
Clean your hands regularly – wash with soap and water, or clean with alcohol-based hand rub
Clean surfaces regularly with disinfectant – for example, kitchen benches and work desks;
Educate yourself about COVID-19. Make sure your information comes from reliable sources;
Avoid traveling if you have a fever or cough and if you become sick while on a flight, inform the crew immediately. Once you get to your destination, make contact with a health professional and tell them about where you have been;
Cough or sneeze into your sleeve. If using a tissue, dispose of the tissue immediately into a closed rubbish bin, and then clean your hands;
Take extra precautions to avoid crowded areas if you are over 60 years old, or if you have an underlying condition;
If you feel unwell, stay at home and call your doctor or local health professional;
If you are sick, stay at home, and eat and sleep separately from your family, use different utensils and cutlery to eat.
If you feel shortness of breath, call your doctor and seek care immediately;
It’s normal and understandable to feel anxious, especially if you live in a country that has been affected. Find out what you can do in your community. Discuss how to stay safe in your workplace, school or place of worship.
