Genotyping data are used in the ongoing verification of measles elimination within Australia. Public Health Laboratory Network (PHLN) provides information on the laboratory diagnoses of measles. PHUs should liaise with GPs and hospital EDs to promote early identification, isolation and appropriate testing of suspected cases, and their notification to PHUs. Measles is characterised by fever and skin rash and usually associated with cough, coryza and conjunctivitis those who have not had two doses of measles containing vaccine) are at increased risk of measles. Measles spreads through droplet transmission from the nose, throat, and mouth of someone infected with the virus. Transmission of Measles. Measles is transmitted by airborne droplets and direct contact with discharges from respiratory mucous membranes of infected persons and less commonly by articles freshly soiled with nose and throat secretions . Where a State/Territory does not have the facility for the WHO accredited measles virus genotyping, samples may be sent to Victorian Infectious Diseases Reference Laboratory (VIDRL). A characteristic maculopapular (non-itchy) rash appears about 2 to 7 days after the onset of the prodrome, and begins on the face or upper neck, spreads to become generalised and typically lasts 4 to 7 days. Table 3: Post-exposure guidelines from 3 days (72 hours) to within 6 days (144 hours) of first exposure to infectious case. A dry sterile swab of the nasal passage combined with a similar swab from the back of the throat is the recommended specimen for detection of viral nucleic acid (PCR).

The incubation period is variable, about 10 days (varying from 7 to 18, occasionally longer) to the onset of fever and about 14 days to the onset of the rash. Cases should avoid contact with susceptible persons, especially children <1 year old and immunocompromised persons. MMR now, then repeat dose at 12 months of age or 4 weeks later (which ever is later) and the usual dose at 18 months. Eye protection must be used where there is a known or potential risk of exposure to splashes. The PHU should facilitate communication with and between the laboratories involved concerning collection of suitable specimens and transport arrangements. Throat swabs are alsosuitable for culture. Cases are usually very unwell and miserable; other symptoms can include anorexia, diarrhoea (especially in infants) and generalised lymphadenopathy3. For eg., if an open wound comes in contact with the blood of a Hepatitis B infected patient, the wounded person might contract the disease. Respiratory droplets can remain infective for at least 1 hour in a close space. Transmission. Check your child's immunization record or contact the doctor to see whether your child has already received the MMR vaccine. This is a mode of transmission for most STIs and many other infectious agents, such as bacterial and viral conjunctivitis (a.k.a. Using a multidisciplinary approach, Human Respiratory Viral Infections is set at the level between the definitive reference work and an essential clinical manual. How can one prevent disease transmission? Causes of Measles. We develop a model, the TSIR (Time-series Susceptible-Infected-Recovered) model, that can capture both endemic cycles and episodic outbreaks in measles. Answer: B. Procedures that are likely to generate aerosols should be conducted in a biosafety cabinet. If arrival at the testing laboratory will be delayed more than 72 hours then, if possible samples should be frozen at -70C and transported on dry ice.
