The top five things to understand about polio

-

 Public health officials have advised medical professionals to be on the lookout for polio, but most doctors are unlikely to be familiar with this highly contagious, potentially fatal disease.




1.Although used internationally, the oral polio vaccination has not been used in Canada since 1996.

The oral polio vaccine's poliovirus can live for weeks and spread through faeces. It can evolve and revert to a form that causes paralysis in underimmunized or immunocompromised individuals when circulating among underimmunized populations. Outbreaks are more likely to occur in areas with poor vaccination rates. Canada uses inactivated polio vaccination, which is disease-free

2.The poliovirus might be present in Canada.

Polio from the vaccine was found in wastewater in the United States and the United Kingdom in 2022.People who have received the vaccine fewer than four times run the risk of contracting an infection.

3.fecal-oral route.

People can shed the extremely contagious poliovirus asymptomatically for weeks and spread it via the fecal-oral route. The disease takes 3-6 days to incubate, and paralysis sets in about 7–21 days. The greatest risk is to children under the age of five.

3.The symptoms of polio can range from asymptomatic to fatal paralysis.

75% of poliovirus infections have no symptoms. In the remaining 24%, symptoms could include digestive problems that progress quickly to weakness and ultimately paralysis over the course of 1-3 weeks. One in 200 people will acquire paralytic polio, and 5–15% of paralysed people will pass away from respiratory muscular paralysis.

4.All patients with abrupt flaccid paralysis should be tested for polio.

Send a stool sample for enterovirus molecular serotyping and enterovirus polymerase chain reaction. Even without test confirmation, if there is a clinical suspicion, it should be reported right once to the patients and public health.

Sometimes all you really need in life is a plate of warm, delectable cookies. There is nothing better, whether for a special after-school snack or a Sunday night treat! I sincerely hope you enjoy this dish as much as my family and I do.   Tips for Making the Best Chocolate Chip Cookies Without Gluten 1.Brown butter is the first ingredient in a secret recipe. Gluten-free cookies occasionally don't have a rich flavour. These cookies have a delicious nutty, toasted, almost caramelised flavour that comes only from brown butter. 2.Add two teaspoons of milk. The next tip is to incorporate a tablespoon of milk into this recipe for gluten-free cookies. This aids in making up for the butter's liquid evaporation during the browning process.

Measles: WHO has declared it an ‘imminent global threat’

 Reduced access to routine healthcare and lower immunisation rates were two effects of the epidemic. As a result, the measles was deemed a "imminent concern in every corner of the world" by the World Health Organization in November 2022. In 2021, a record number of around 40 million kids missed at least one dose of the measles vaccine, according to their account. A respiratory virus causes measles. Similar to COVID, transmission is fueled by respiratory droplets and aerosols, which are transmitted from person to person (airborne transmission ). In mild cases, the infection causes a rash and fever. However, severe cases can result in pneumonia, blindness, and encephalitis (brain swelling). There are roughly 128,000 fatalities every year and 9 million cases.  The measles vaccine is quite effective, and it can be given alone or in conjunction with other shots like the mumps and rubella vaccines to form the MMR immunisation. The majority of nations use a two-dose regimen, wit...
