This article will in turn help you find out the above issues, thereby proactively preventing yourself, your family and your loved ones especially when you are traveling or living in Hanoi, Vietnam.
What is Corona Virus?
Coronavirus (it’s short name is Corona), also known as corona virus, is a group of viruses of the Coronavirinae subfamily in the Coronaviridae family, according to the Nidovirales Department. Coronavirus causes disease in mammals, including humans and birds. In humans, the virus that causes respiratory infections is usually mild but in rare cases can be fatal.
Coronavirus is a enveloped virus with a positive single-stranded RNA genome and with a spiral symmetrical nucleocapsid. The coronavirus genome size ranges from 26 to 32 kilo base pair, the largest for RNA viruses.
The name “coronavirus” is derived from the Latin corona, meaning crown or halo, and refers to the characteristic appearance of virions under an electron microscope (EM) with a large margin, forming an image. photo such as royal crown or corona. This morphology is generated by mutated peplomers of the virus, which are proteins that reside on the surface of the virus and identify the host.
Proteins that contribute to the overall structure of all coronaviruses are spike (S), envelope (E), membrane (M) and nucleocapsid (N)). In the specific case of the SARS coronavirus, a receptor binding domain identified on S mediates the binding of the virus to its cell receptor, the enzyme converting angiotensin 2 (ACE2).). The coronavirus virus (especially members of the Betacoronavirus A subgroup) also has a shorter spiny-like protein called hemagglutinin esterase (UK).
Coronavirus usually causes the symptoms of a common cold, infection of the nose, sinuses or throat and spreads through sneezing and coughing. However, it can lead to more serious respiratory illnesses such as severe acute respiratory syndrome (SARS) and death.
What is the manifestation of corona virus infection?
When infected with corona virus, the patient has mild to moderate upper respiratory illnesses, similar to the common cold.
Symptoms of corona virus infection include runny nose, cough, sore throat, headache and fever. These symptoms may last for several days. For those with weakened immune systems, the elderly and children, it is possible that corona virus also causes diseases of the lower respiratory tract such as pneumonia or bronchitis.
nCoV is a respiratory disease. Signs of the illness are fever, cough, shortness of breath, manifested as acute pneumonia, which is more noticeable for people who are returning from China or returning from an epidemic area, who are at risk of coming into contact with an infected person. .
Because this is a viral pneumonia (new strain of coronary virus), antibiotics do not work, current antiviral drugs used for common influenza are also ineffective. The best way is still hospital monitoring.
How is corona virus spread?
Currently, China has confirmed that the new strain of corona virus, the Wuhan pandemic pneumonia virus, can be passed from person to person. In Vietnam, the US and Thailand, human-to-human transmission has been reported. The World Health Organization (WHO) has declared an outbreak of the new strain of corona virus (2019-nCoV) from China as a “global medical emergency”.
Strains of corona virus can be transmitted through contact between humans and animals. Scientists believe that the MERS outbreak originated from camels, while scientists suspected civets as animals that caused SARS outbreaks.
In humans, the virus spreads from person to person through contact with infected body fluids. Depending on the degree of spread of the virus, coughing, sneezing or shaking hands can expose people to exposure.
The virus can also be spread by touching someone on the object with their hands, then on their mouth, nose, and eyes. Patient care workers are also sometimes exposed to the virus when handling patient waste, according to the US Centers for Disease Control and Prevention (CDC).
How to treat corona virus?
There is no specific treatment. In most cases, the symptoms go away on their own. Your doctor can relieve these symptoms by prescribing pain medication or fever.
According to the CDC, staying in a room with adequate humidity or a hot bath will also help relieve sore throat and cough.
Patients should drink plenty of water, fluids, rest and sleep as much as possible. In the event that symptoms do not improve and even worsen, seek immediate medical attention.
What medicine can cure?
So far, at least Vietnam and China have recovered from their illness after testing positive for this new strain of corona virus. However, there is no cure for this new strain of corona virus.
Xinhua recently reported that researchers in China have selected 30 drugs to test anti-coronary virus causing pneumonia in Wuhan, including existing drugs, traditional medicines and natural products. biologically active.
These are not drugs used to treat illnesses, but were initially chosen as “candidate” drugs to be tested, Xinhua quoted a statement from the Chinese Academy of Sciences (CAS).
Based on the latest research, the research team screened commercially available drugs as well as highly effective compounds and medicinal plant compounds. Thereby, they selected 30 types of anti-virus drugs from the combination of screening and enzyme testing.
The selected categories include 12 anti-HIV drugs such as indinavir, saquinavir, lopinavir, carfilzomib and ritonavir, as well as 2 respiratory syncytial, schizophrenia and immunosuppressive drugs.
In addition, a number of traditional Chinese drugs that are believed to have an anti-viral effect against the Wuhan virus, including the tigress (polygonum cuspidatum), also known as the mandarin and blood root, are also included in the weight list. Reminders used to treat.
The case of corona virus infection was first treated in Cho Ray Hospital in Vietnam with antiviral drugs, broad-spectrum antibiotics and other supportive therapies.
What are the ways to prevent coronary virus disease?
There is currently no vaccine to prevent new strains of corona virus. Tests of the vaccine against the MERS virus strain are still in development.
However, people can reduce the risk of infection by avoiding contact with those who are ill. Wear a surgical mask. Wash your hands often with soap and water for at least 20 seconds. Gargle with antiseptic water to prevent pneumonia.
If you are sick, stay home and avoid crowds, avoid contact with others. Cover your cough and sneeze, preferably with a towel, to reduce the spread of respiratory secretions. Disinfect objects and surfaces you touch to avoid spreading the disease to others.
If you have been in contact with an infected person with corona virus, if you have clinical symptoms such as fever, cough, shortness of breath, you must go to health facilities for isolation and testing. If you do not have symptoms, you should also isolate yourself at home for 14 days, wearing a mask when contacting other people.
Medical examination and treatment when suspected corona virus infection in Hanoi?
The Ministry of Health of Vietnam has just instructed the referral division to receive patients with suspected coronary virus infection. Accordingly, the National Hospital of Tropical Diseases (Kim Chung Campus, Dong Anh, Hanoi) receives patients from Ha Tinh back out, in case of out of reserve beds, the patients are transferred to Bach Mai Hospital and Diseases. National Hospital of Pediatrics in Hanoi.
For the health of yourself and your loved ones, as well as your community, please follow the above requirements to join hands to prevent and eliminate this virus. If you have symptoms of this virus, you need to immediately visit the above facilities in Hanoi to treat it soon!
