COVID 19 DIFFERENTIAL DIAGNOSIS

The initial stages of coronavirus infection are nonspecific and include symptoms typical of multiple respiratory illnesses such as viral infections etc. The coronavirus can cause a range of symptoms, which include fever, cough, sore throat, and headaches. In severe cases, difficulty in breathing and deaths can occur. Viral infections (which may co-occur with COVID-19) in the differential diagnosis include the following: 1. Influenza Influenza is a viral infection that attacks the respiratory system (nose, throat, and lungs). Symptoms include fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue. Flu is primarily treated with rest and fluid intake to allow the body to fight the infection on its own. Paracetamol may help cure the symptoms, but NSAIDs should be avoided. An annual vaccine can help prevent the flu and limit its complications. 2. Parainfluenza Parainfluenza refers to a group of viruses called human parainfluenza viruses (HPIVs). All forms of HPIV (4) cause an infection in either the upper or lower respiratory tract. Symptoms of HPIVs are similar to the common cold. In mild cases, the viruses are often misdiagnosed— healthy people infected with an HPIV recover without any treatment. 3. Human metapneumovirus HMPV infects airway epithelial cells in the nose and lungs. This infection is associated with 6% to 40% of respiratory tract infections in hospitalized and outpatient children. 4. Human rhinovirus The rhinovirus- the most common viral infectious agent and a predominant cause of the common cold. Symptoms usually include runny nose, nasal congestion, sneezing, sore throat, and cough. These symptoms are accompanied by fatigue, malaise, or loss of appetite. Fever and extreme exhaustion are more common in influenza. 5. Adenovirus Adenoviruses infect the lining of eyes, airways and lungs, urinary tract, intestines, and nervous system. They cause fever, coughs, sore throats, diarrhea, and a pink eye. 6. Respiratory syncytial virus Respiratory syncytial virus (RSV) is a common respiratory virus that usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be severe, especially for infants and older adults. RSV is the most common cause of bronchiolitis and pneumonia in children younger than one year of age. It is also a significant cause of respiratory illness in older adults. Bacterial infections in the differential diagnosis include the following: 1. Haemophilus influenzae pneumonia Haemophilus influenzae, a type of bacteria, can cause many kinds of infections. These infections range from mild, ear infections, to severe, like bloodstream infections. The most common types of invasive disease caused by H. influenzae are: Pneumonia Bloodstream infection Meningitis Epiglottitis Cellulitis Infectious arthritis 2. Streptococcus pneumoniae pneumonia Streptococcus pneumonia is part of the normal upper respiratory tract flora. As with much natural flora, it can become pathogenic under the right conditions, typically when the immune system of the host is suppressed. Pneumonia is the most common of the S. pneumoniae diseases. Symptoms include fever and chills, cough, rapid breathing, difficulty breathing, and chest pain. For the elderly, they may consist of confusion, low alertness, and the formerly listed symptoms to a lesser degree. 3. Moraxella catarrhalis pneumonia These bacteria is known to cause otitis media, sinusitis, bronchitis, and laryngitis. Atypical pneumonia in the differential diagnosis includes the following: 1. Legionellosis Legionnaires' disease or legionellosis, is a form of atypical pneumonia caused by any Legionella bacteria. Signs and symptoms include cough, shortness of breath, high fever, muscle pains, and headaches. Nausea, vomiting, and diarrhea may also occur. 2. Mycoplasma pneumoniae pneumonia Mycoplasma pneumoniae is a "atypical" bacteria that commonly cause mild infections of the respiratory system. Pneumonia caused by M. pneumoniae is sometimes referred to as "walking pneumonia" since symptoms tend to be milder than pneumonia caused by other germs.

Nice Information & Explantations

Asymptotic pts , whether they should be treated with drugs, certainly they can quartined & if there are no guide lines about it what could be the medico-legal implications of it. Recently I got a what's app messege which quotes an article in Guardian dt 2/7/ 2020 that corona is a greatest hoax , what's the opinion of the house.
