Influenza-B virus was identified in 102 children admitted to hospital during two epidemics in 1973 and 1974, enzbling the symptomatology of infection with this virus to be assessed in detail for the first time. Abdominal pain, often severe enough to require differentiation from acute appendicitis, emerged as a dominant symptom, especially in older children. Respiratory symptoms were often insignificant, although the lower respiratory tract was sometimes involved. Other symptoms in some children included convulsions and acute myalgia. The immunofluorescent method of virus diagnosis was found to be reliable for influenza B, except in a few cases ehere nasopharyngeal secretions were scanty, giving 97-5 percent copositivity with standard isolation techniques. The rapid result provided by immunofluorescence was helpful in clinical diagnosis and management and also in the control of hospital cross-infection.

Experimental and clinical experience with compounds containing antimony have shown that the trivalent compounds are generally more toxic than the pentavalent ones. APT can cause severe pain and tissue necrosis and is therefore not given by intramuscular or subcutaneous injection. APT has the actions and uses of AST, but it is less soluble and more irritating than the sodium salt which is therefore more suitable for intravenous use. Trivalent antimony compounds are toxic when used topically. Adverse effects are similar for all trivalent compounds, and include nausea, vomiting, weakness and myalgia, abdominal colic, diarrhoea, and skin rashes, including pustular eruptions. Hypersensitivity reactions also occur. Respiratory symptoms include cough, dyspnoea, and chronic lung changes. Cardiotoxicity is the most important and may produce arrhythmias, myocardial depression and damage, Stokes-Adams attacks, heart failure, and cardiac arrest. Hepatic damage and necrosis, as well as blood dyscrasias, may occur. Toxic effects on the kidney may follow chronic use. Continuous treatment with small doses of antimony may give rise to symptoms of subacute poisoning, similar to those of chronic arsenic poisoning, due to accumulation of antimony in the body, especially if trivalent compounds are used, because of their long biological half-lives. Reproductive disorders and chromosome damage have been reported; antimony compounds are, therefore, potentially toxic to reproduction and have mutagenic, and oncogenic potential. Antimony compounds should, therefore, not be used during pregnancy or in the presence of hepatic, renal, or heart disease. Pentavalent antimony preparations especially the organic compounds, together with non-metallic synthetic preparations, such as the diamidines, have now replaced APT for use in leishmaniasis. Because of the toxicity of antimony compounds, investigations have been undertaken to reduce their adverse effects by combining them with chelating agents. These preparations appear to have reduced the toxic effects of antimony without affecting the efficacy of the preparations. Liposome-encapsulated antimony products have, more recently, been shown to be much less toxic because of the reduced dose of the antimony compound required for effective therapy. The historical uses of antimony were based on the belief that the topical and systemic adverse effects, for example, skin eruptions and diarrhoea and vomiting, were signs that the condition being treated was responding by being brought to the surface to relieve congestion at the diseased area. There is no evidence in topical use, but there is evidence that such use can cause severe reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

A substudy analysis was conducted to determine the clinical characteristics associated with symptomatic, laboratory-documented influenza (LDI) among 2215 veterans with chronic obstructive pulmonary disease who participated in Department of Veterans Affairs Cooperative Study 448 and who received trivalent inactivated influenza virus vaccine with or without intranasal live-attenuated, cold-adapted influenza vaccine. Of 585 evaluable first occurrences of acute respiratory illnesses, 94 (16%) were LDI. Respiratory symptoms of cough, sputum production, and dyspnea occurred in >90% of patients with LDI; 68% had documented or subjective fever, and 81% had myalgias. Stepwise logistic regression identified only fever and myalgia as being statistically associated with LDI. During the influenza outbreak period, the positive predictive value of fever and myalgia was 41%. Clinical criteria were poor predictors of LDI in these older, vaccinated patients with chronic lung disease. Additional studies are warranted to define optimal methods for the diagnosis of influenza among older persons with chronic obstructive pulmonary disease.

It was on 31st December 2019, that a cluster of pneumonia cases was reported to the World Health Organization (WHO) by China. The initial investigations revealed the cases to be due to a previously unknown "never before seen strain of coronavirus". Coronaviruses are a group of viruses, which are normally present among animals such as cows, bats, camels and cats. The disease was officially named COVID-19 by WHO on 11th February 2020. The International Committee on Taxonomy of Viruses named the virus as SARS-CoV-2 due to its resemblance to SARS coronavirus. According to WHO's Situation Report-28 as of 17th February 2020, globally there were 71,429 confirmed cases, which included both laboratories confirmed and clinically diagnosed cases (applicable only to Hubei province of China). Cases are clinically diagnosed based on their signs and symptoms and chest x-rays without laboratory testing. More than 99% of these are in China i.e. 70,635 and 794 are outside China. The cases reported outside of China belong to 25 countries in various regions of WHO: China having the epicenter of the disease bears the greatest brunt, with 1772 deaths. The three deaths outside China have been reported in Philippines, Japan and France. The case fatality rate of COVID-19 ranges between 2-3% A wide spectrum of disease, ranging from mild to severe, has been reported in confirmed cases of COVID-19. Respiratory symptoms, fever, cough, dyspnoea, myalgia, fatigue, breathing difficulties and bilateral lung infiltrates on C.T are common findings. Pakistan so far has not reported any confirmed case of COVID-19. Government is showing its commitment towards the threat of importation. This novel coronavirus, called as a "devil" by Chinese Prime Minister, Xi Ping is really an enigma.
