10856 Severe Acute Respiratory Syndrome Sars

Overview

SARS is a serious form of pneumonia caused by a virus. It affects the lungs and can make it very hard to breathe. The disease first appeared in 2002 and spread globally, but it has not appeared since 2004.

No. SARS is extremely rare today. The last known natural case happened in 2004, and there have been no outbreaks since then.

People of all ages can get SARS, but it caused the most severe illness in middle-aged and older adults, especially those with existing health conditions like diabetes, heart disease, or lung disease.

Symptoms

Common symptoms

• Fever
• Dry cough
• Shortness of breath or difficulty breathing
• Muscle aches
• Tiredness
• Headache
• Chills and sore throat

Causes

Main causes

• Infection with the SARS coronavirus (SARS-CoV-1)
• Breathing in droplets from an infected person who coughs or sneezes
• Touching your eyes, nose, or mouth after touching surfaces contaminated with the virus

Risk factors

• Close contact with someone who has SARS
• Travelling to an area where SARS is known to be spreading
• Working in healthcare and caring for infected patients
• Living in a household with an infected person
• Older age or having chronic health conditions

When to see a doctor

See a doctor urgently if:

• If you develop fever and breathing problems and have recently travelled to a place with known SARS activity
• If you have been in close contact with a person diagnosed with SARS

Book a routine appointment if:

• If you have a persistent cough and fever and are worried about a lung infection, make an appointment with your doctor

Diagnosis

A doctor will ask about your symptoms, travel history, and contact with sick people. They will listen to your lungs. SARS can only be confirmed by laboratory tests.

Tests that may be done

• Swab from the nose or throat
• Blood tests
• Chest X-ray
• Sample of phlegm from the lungs

What to expect at your appointment

If SARS is suspected, you will be isolated quickly to protect others. Your oxygen levels and breathing will be monitored closely. Testing usually happens in a hospital setting.

Treatment

There is no specific cure for SARS. Treatment focuses on easing symptoms and supporting the lungs so they can heal. Most people receive care in a hospital, especially if their breathing is affected.

Self-care at home

• Rest as much as possible
• Drink plenty of fluids to prevent dehydration
• Use over-the-counter fever relief as advised by a pharmacist or doctor
• Keep room air moist and cool to ease breathing

Medical treatments

In hospital, treatment may include oxygen therapy, fluids through a drip, and medicines to reduce fever and inflammation. In severe cases, a ventilator can help with breathing. There is no approved antiviral drug specifically for SARS, so treatment is supportive.

When is surgery considered?

Surgery is not used to treat SARS.

Living with this condition

Recovery from SARS can take weeks or even months. Take things slowly and be patient with your body. Rest, sleep, and gradually rebuild your strength.

Lifestyle tips

• Do not smoke and avoid secondhand smoke
• Wash your hands regularly to prevent other infections
• Avoid heavy physical activity until your doctor says it is safe
• Keep good ventilation at home

Diet and exercise

Eat a balanced diet with plenty of fruit, vegetables, and protein. Gentle activities like short walks can help once you feel ready, but always follow your doctor's advice about how much activity is safe.

Mental health and emotional wellbeing

Serious illness can be emotionally hard. You may feel anxious, low, or tired for a long time. These feelings are normal, but if they do not improve, talk to your healthcare team or a mental health professional.

Prevention

There is no vaccine against SARS, and the current risk is very low. If a new case ever appears, public health measures such as isolation and contact tracing would help stop it spreading.

Vaccines

No SARS vaccine is currently available.

Screening programmes

Routine screening for SARS is not needed now, but border health checks may be introduced during any future outbreak.

Complications

If left untreated

• Pneumonia
• Acute respiratory distress syndrome (ARDS), a severe lung injury
• Respiratory failure, meaning the lungs cannot supply enough oxygen
• Secondary bacterial lung infections
• Organ failure in very severe cases

Long-term outlook

Most people who had SARS recovered with supportive care, although some were left with lasting lung weakness. Because the disease has not reappeared in years, public health systems are now much more prepared. With careful monitoring and early care, the hope is that any future outbreak can be contained quickly.
