It can cause severe complications, particularly in malnourished children and people with reduced immunity. TRANSMISSION Measles virus, the causative agent, is a single-stranded negative-sense RNA virus belonging to the family Paramyxoviridae, genus Morbillivirus. Measles virus is efficiently transmitted by aerosol entering the respiratory tract or by direct contact with respiratory secretions, causing a systemic infection. This disease can also be transmitted through sexual intercourse. After an incubation period of 8–12 days, measles signs and symptoms will begin to show. SIGNS & SYMPTOMS Fever Cough Coryza common cold Conjunctivitis Sore throat Headache Abdominal pain Photophobia from iridocyclitis Rash first noted on the face and neck which increases in number for 2 or 3 days, especially on the trunk and face. Koplik’s spots bluish-white, slightly raised lesions, appears on the buccal mucosa, usually opposite the first molar, and occasionally on the soft palate, conjunctiva, and vaginal mucosa 1 DIAGNOSIS Although the diagnosis of measles is usually determined from the classic clinical picture, laboratory identification and confirmation of the diagnosis are necessary for public health and outbreak control. Laboratory confirmation is achieved by means of the following: Serologic testing for measles-specific IgM or IgG titers Isolation of the virus Reverse-transcriptase polymerase chain reaction (RT-PCR) evaluation COMPLICATIONS Complications from measles have been reported in every organ system (refer table 1). It usually happens among very young infant or immunocompromised patient. Many of these complications are caused by disruption of epithelial surfaces and immunosuppression. 2 TREATMENT There is no specific antiviral treatment for measles. Complications May require antibiotic treatment. Other treatments Focus on management of signs and symptoms. People with low levels of vitamin A are more likely to have a more severe case of measles. The WHO recommends vitamin A supplementation for all children diagnosed with measles : Age Dose < 6 months 50,000 IU/day PO for 2 doses 6-11 months 100,000 IU/day PO for 2 doses > 1 year 200,000 IU/day PO for 2 doses Children with clinical signs of vitamin A deficiency : The first 2 doses as appropriate for age, then a third age-specific dose given 2-4 weeks later IMMUNIZATION PROGRAM In Malaysia, measles is mainly prevented by the measles, mumps and rubella (MMR) combination vaccine. In some countries, the measles, mumps, rubella and varicella (MMRV) combination vaccine has been used in the vaccination program. Almost all people who have 2 doses of a measles-containing vaccine will be protected against measles. Table 2. Measles vaccine and MMR vaccine program in Malaysia 3 ANTI-VACCINE ISSUES The measles vaccine has almost eliminated measles in the United States of America. The cases have declined from an estimated 5 million a year to virtual disappearance. However, the latest issues regarding MMR vaccine contribution in the development of autism in children has once again give arise to the once forgotten disease. In 2011, the number of people with measles in the United States was higher than usual. There were 220 people reported to have measles. That’s more than any year since 1996. The same trend was also observed in Malaysia during 2011, when there were 1603 confirmed cases of measles, compared to 2010 with only 74 people with measles. The suggestion that MMR vaccine might lead to autism had its origins in research by Andrew Wakefield, a gastroenterologist, in the United Kingdom. In 1998, Wakefield and colleagues published an article in The Lancet claiming that the measles vaccine virus in MMR caused inflammatory bowel disease, allowing harmful proteins to enter the bloodstream and damage the brain. When the finding could not be reproduced by other researchers, the validity of this finding was later called into question. Moreover, the findings were further discredited when an investigation found that Wakefield did not disclose he was being funded for his research by lawyers seeking evidence to use against vaccine manufacturers. Furthermore, large studies of children done in the United States, the United Kingdom, and Denmark found no link between MMR vaccine and autism. In a nutshell, people who choose not to vaccinate their children actually make a choice for other children and put them at risk.

It is caused by a type of bacteria called Bordetella pertussis. These bacteria attach to the cilia (tiny, hairlike extensions) that line part of the upper respiratory system, produce toxins that paralyze the cilia, and cause inflammation of the respiratory tract, which interferes with the clearing of pulmonary secretions. Pertussis occur mainly in infants and children, and only found in humans. Transmission of pertussis can occur through direct face-to-face contact, through sharing Bordetella pertussis of a confined space, or through contact with oral, nasal, or a fastidious, gram-negative bacterium, respiratory secretions from an infected source. The aerobic , coccobacillus capsulate of the incubation period of the disease is 5 to 10 days (maximum is up to 21 days). The infectious period is at the beginning of genus Bordetella the catarrhal period which is prior to cough onset and up to 21 days after the cough started. Pertussis can cause violent and rapid coughing, over and over, until the air is gone from the lungs and patient forced to inhale with a loud "whooping" sound. This extreme coughing can cause vomiting and exhaustion. CLINICAL MANIFESTATIONS The clinical course of the illness is divided into three stages: catarrhal, paroxysmal and convalescent. Pertussis has an insidious onset with catarrhal symptoms that are indistinguishable from those of minor respiratory tract infections. The cough, which is initially intermittent, becomes paroxysmal. In typical cases paroxysms terminate with inspiratory whoop and can be followed by posttussive vomiting. Paroxysms of cough, which may occur more at night, usually increase in frequency and severity as the illness progresses and typically persists for 2 to 6 weeks or more. After paroxysms sub- side, a nonparoxysmal cough can continue for 2 to 6 weeks or longer. 5 The spread of pertussis can be limited by decreasing the infectivity of the patient and by protecting close contacts. Symptoms may be lessened if antimicrobial treatment is started early in the course of illness during the first 1 to 2 weeks, prior to paroxysmal coughing. If treatment begins later in the course of illness, it may not decrease symptoms but will shorten the period of infectivity. When patient is on antibiotics, the infectious period is at the onset of cough until the 5th day of the 14 days of recommended antibiotic treatment. Patients with pertussis are infectious from the beginning of the catarrhal stage through the third week after the onset of paroxysms (multiple, rapid coughs) or until 5 days after the start of effective antimicrobial treatment Treat persons aged >1 year within 3 weeks of cough onset and infants aged <1 year and pregnant women (especially near term) within 6 weeks of cough onset The need for antibiotic prophylaxis is particularly important in the following high risk groups: i. infants ii. non-immunized children iii. immunocompromised individuals iv. pregnant women v. individuals with chronic respiratory illness, including asthmatics ANTIMICROBIAL AGENTS FOR TREATMENT AND PROPHYLAXIS OF PERTUSSIS Antibiotic Infant < 6months Erythromycin < 30 days of age : not preferred (associated with infantile hypertrophic pyloric stenosis) ≥ 6 months & children 40-50 mg/kg/day in 4 divided doses for 14 days (maximum 2g/day) Adult 2g/day in 4 divided doses for 14 days Use if azithromycin unavailable : 40-50mg/kg/day in 4 divided doses for 14 days.

Suspected cases who do not receive antibiotics should be isolated for 3 weeks. Vaccination does not provide life-long protection. It provides high level of protection Minimum Period of isolation of Contacts If contact is symptomatic use the same restriction as for cases If contact is an asymptomatic (healthcare worker not receiving prophylaxis) exclude from workplace for 21 day after last exposure or if unknown, for 21 days after the onset of the last case setting If the contact is asymptomatic (not a health care worker) and exposed within the 21 days patient should receive antibiotic prophylaxis but no isolation is generally required Quarantine Inadequately immunized household contacts less than 7 years of age should be excluded from schools, day care centers and public gatherings for 21 days after last exposure or until the cases and contacts have received 5 days of a minimum 14 - day course of appropriate antibiotics.
