Learn about the nature of the SARS-like virus, its symptoms, and prevention methods, as well as how to distinguish it from other common respiratory infections.
What is a SARS-like virus?
This virus belongs to the coronavirus family, named for its crown-like appearance under a microscope. This family typically causes respiratory infections ranging from mild to moderate in humans, while they may cause gastrointestinal, neurological, and respiratory diseases in animals.
This large family of viruses includes common cold pathogens as well as more dangerous strains such as Severe Acute Respiratory Syndrome (SARS). New patterns of these viruses have emerged causing acute pneumonia; while most infected individuals recover with simple supportive treatments, rare cases may experience serious complications affecting the kidneys and respiratory system.
Symptoms of a SARS-like virus infection
Initial signs of infection are similar to common flu symptoms and include:
- Standard fever or an increase in temperature reaching 38°C (100.5°F) or higher.
- Dry cough, sneezing, and runny nose.
- Headache and muscle aches.
- Sore throat.
- Diarrhea may appear in some cases, and after about a week, the condition may progress to shortness of breath.
How infection spreads and risk factors
The virus is transmitted through several routes, most notably:
- Droplets released into the air during coughing, sneezing, or speaking.
- Direct contact with a patient’s secretions and fluids.
- Contaminated hands or touching contaminated surfaces such as doorknobs and phones.
The virus enters the body through the membranes of the pharynx, larynx, and nose. The likelihood of infection increases for people who have close contact with infected individuals, such as family members and healthcare workers. The risk of complications, such as heart, liver, or respiratory failure, increases for those over sixty years old or those with chronic diseases such as diabetes, hepatitis, heart and chest diseases, and immunodeficiency.
Prevention and treatment methods
There is currently no specific and effective cure for SARS syndrome, as antibiotics do not affect viruses, and antiviral drugs have not shown significant benefit. Therefore, prevention relies on the following measures:
- Washing hands frequently with soap and water or using an alcohol-based sanitizer with at least 60% alcohol.
- Wearing protective masks (surgical masks) in crowded places or when caring for a patient.
- Disinfecting contaminated surfaces with household disinfectants.
- Washing the infected person’s clothes and towels with hot water and soap.
- Ensuring the receipt of influenza and meningitis vaccinations.
Frequently Asked Questions
Is the SARS-like virus highly contagious?
Health experts indicate that this virus is not highly contagious, as evidenced by the lack of widespread infection during certain periods.
How long does the illness last?
The infection lasts for several days and can sometimes reach two weeks; the patient often recovers spontaneously without the need for treatment.
Are there vaccines available against SARS?
Researchers have conducted studies to develop vaccines, but none have been tested on humans so far.
When should you visit a doctor?
You should see a doctor immediately in the following cases:
- The appearance of respiratory infection symptoms.
- The appearance of flu-like symptoms accompanied by fever after traveling abroad.
