Presentation Transcript

  1. Do you know that coughing sneezing and myalgia are some sign and symptoms for corona virus? • Do you know that the corona virus was called so due to its for the crown-like spikes on their surface? • Do you know that transmission of virus occurs through direct contact with the an infected person? • Join us as we reveal the facts about such an important spread of an obscure opponent “ CORONA VIRUS”!

  2. Microbiology Intro BS 1 nursing

  3. VIRUS

  4. A virus is a small infectious agent that can replicate only inside the living cells of an organism. Viruses can infect all types of organisms, from animals and plants to bacteria. • Viruses vary in size & shape

  5. Respiratory system :The respiratory system (or ventilatory system) is the biological system that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. • The respiratory system includes: • Nose and nasal cavity • Pharynx • Larynx • trachea • bronchi and their smaller branches • Lungs that contain the terminal air sacs or alveoli

  6. Respiratory system and new corona virus! • The new coronavirus can easily infect the cells of the airways of the human lung and in fact is as adept at doing so as a common cold virus. • the new virus multiplied at a faster rate than the SARS virus did in the human cells. • It does not need a phase of adaptation.

  7. Chest radiographs of index patient with SARS which is similar to that of patient with CoV SARS virus. day 5 day 10 day 13 day 15.

  8. corona viruses

  9. What are coronaviruses? • they are common viruses, first identified in the mid 1960s;that infect not only animals but humans as well. • This particular strain of coronavirus is distinct from other known coronaviruses and SARS. • named for the crown-like spikes on their surface. • usually causes mild to moderate upper-respiratory tract illnesses & even acute respiratory infection presenting as pneumonia.

  10. Corona viruses are currently divided into 4 antigenic groups:(note: recently other groupings have been proposed) • Group I coronavirusesTGEV, FIPV, CCV, PRCV, HCoV-229E, RbCoV, FECoVSpike not cleavedM is N-glycosylatedNo HE proteinNo ORF 2 • Group II coronavirusesMHV, BCV, HCoV-OC43, HEV, SDAV, SARS-CoVCleaved spikeM is O-glycosylatedHE proteinORF 2 present

  11. Group III coronaviruses (Avian group)IBV, TCoVCleaved SpikeM is N-glycosylatedNo HE proteinNo ORF 2 • Group IV coronaviruses (similar to Group II) SARS-CoV • -In group III coronaviruses spike forms the basis for different serotypes

  12. What are the diseases that coronaviruses cause in humans? • HCoV-229E • HCoV-OC43 • NL63/NL(New Haven coronavirus) • HKU1-CoV • HCoV-EMC previously known as Novel coronavirus 2012. • But the most common disease is the SARS-COV& the most recent disease namely MERS-CoV.Since All cases have had some link to the Middle East

  13. SARS vs. new CoV- sars

  14. Is MERS-CoV the same as the SARS virus? No. MERS-CoV is not the same virus that caused severe acute respiratory syndrome (SARS) in 2003

  15. SARS VS corona virus

  16. What is MERS? Middle East Respiratory Syndrome (MERS) is a viral respiratory illness. MERS is caused by a coronavirus called “Middle East Respiratory Syndrome Coronavirus” (MERS-CoV). • What is MERS-CoV? MERS-CoV is a beta coronavirus. It was first reported in 2012 in Saudi Arabia. MERS-CoV used to be called “novel coronavirus,” or “nCoV”. It is different from other coronaviruses that have been found in people before.

  17. Source of MERS-CoV

  18. Risk factors The greater the population the greater risk in public places occurs. Low immunity due to any kind of disease, infection …

  19. Incubation • Scientists don't know how long the virus sticks around in the body before showing symptoms. the first symptoms of infection showed up within 10 days.

  20. There is very limited information on its impact, transmission and severity at this stage. First symptoms appear • The first symptoms of the virus include fever and upper respiratory tract infection, and a cough — similar to a flu or cold. Shortness of breath - in the later stage • Sore throat • Extreme  • fatigue  • Diarrhea • Headaches • Fever • Lethargy • loss of appetite • Myalgia - pain in the muscles • Chills

  21. Multiple organ dysfunction • About seven days after getting to the hospital, your liver enzymes — an indication of the organ's health — will start to rise. Multiple patients suffered kidney failure along with their respiratory symptoms. • Death  • Eventually your body gives in and you die. The first patient died 11 days after being admitted to the hospital. His death was deemed to be from "progressive respiratory and renal failure."

  22. MERS Cases and Deaths, April 2012 - May 2013

  23. -If residence in or history of travel to the Arabian Peninsula or neighboring countries within 10 days before onset of illness • -a person with an acute respiratory infection (e.g. pneumonia or Acute Respiratory Distress • Syndrome) • -If close contact with a probable or confirmed cases within 10 days before onset of illness • -A person with laboratory • confirmation of infection with • MERS-CoV.

  24. How do I test for MERS-CoV? Is there a lab test? Lab tests (polymerase chain reaction or PCR) for MERS-CoV are available at CDC and other international labs. Otherwise, these tests are not routinely available.

  25. Is it contagious?

  26. A possible case or a case with a positive laboratory result (preliminary or confirmed) for MERS-CoV : Standard, droplet and contact precautions with additional precautions for aerosol generating procedures Standard, airborne and contact precautions for patients who are in an intensive care unit or require aerosol generating procedures on an ongoing basis Note: If a contact of a case with a positive laboratory result (preliminary or confirmed) develops a respiratory tract infection; the above precautions should be applied.

  27. Are there treatments? • Scientists studying the Human Coronavirus-Erasmus Medical Center, which first appeared April 2012 in the Middle East, have discovered helpful details about its stronghold tactics. • Their findings predict that certain currently available compounds might treat the infection. These could act, not by killing the virus directly, but by keeping lung cells from being forced to create a hospitable environment for the virus to reproduce.

  28. The new virus appears to specifically hamper the work of several genes that enable the body to sense the presence of viruses. The scientists believe such gene re-tuning by the virus could significantly lower the ability of lung cells to mount an appropriate antiviral reaction. • At present no proven treatment exists for human coronavirus EMC. Because the virus succeeds in multiplying by hijacking cellular processes initiated in response to infection, the scientists searched for drugs that might target these cellular responses, and in so doing stop the virus from reproducing.

  29. There are currently no vaccines available to protect you against human coronavirus infection.  You may be able to reduce your risk of infection by—washing your hands often with soap and water, not touching your eyes, nose, or mouth.

  30. avoiding close contact with people who are sick.

  31. People coming in close contact with infected individuals should use a mask and eyewear to cover their nose, eyes, and mouth to prevent transmission from sneezing or coughing.

  32. What should I do if I get sick?  If you have an illness caused by human coronaviruses, you can help protect others by—staying home while you are sick, avoiding close contact with others, covering your mouth and nose when you cough or sneeze, and keeping objects and surfaces clean and disinfected.

  33. Most people with coronavirus illness will recover on their own. • However, some things can be done to relieve your symptoms, such as: • taking pain and fever medications (Caution: Aspirin should not be given to children) • using a room humidifier or taking a hot shower to help ease a sore throat and cough. • If you are sick, you should —drink plenty of liquids, and • stay home and rest. • .

  34. If you are concerned about your symptoms, you should see you healthcare provider
