The current measles outbreak has gripped US states like Texas and New Mexico leaving people worried whether it would become a new pandemic. According to the Texas Department of State Health Services as of February 21, 90 cases were diagnosed in the last month in the South Plains area, with at least 77 of them were reported in children and teens under 17.

Measles is highly contagious and can be deadly. The outbreak, which started spreading in late January, has resulted in multiple hospitalizations, with at least nine confirmed cases and three probable cases as of early February. Health officials caution that at least one in five infected individuals will have to be hospitalized, highlighting the severity of the situation.

Misinformation surrounding vaccines and with the new Trump administration anti-vaccine campaigs, has causing parents to hesitate or refuse vaccination.

Furthermore, the country down under Australia is also witnessing a surge in measles cases as health officials in Sydney have issued an urgent alert, urging residents to watch for measles symptoms after an infected individual visited several places in Sydney over the last seven days.

Authorities report that the traveller had returned from South East Asia where there are ongoing outbreaks of measles.

What Are The Symptoms Measles?

Key symptoms of measles include fever, a runny nose, sore eyes, and a cough. Typically, a red, blotchy rash appears three to four days later, spreading from the head down to the body. Symptoms can manifest between 7 and 18 days after exposure.

Anyone who experiences these symptoms after potential exposure should immediately contact their doctor or emergency department. It is crucial to call ahead before visiting to avoid potentially exposing others in the waiting room. Dr. Selvey also highlighted that ongoing measles outbreaks are occurring in various parts of the world, making awareness and prompt action essential.

Why It Is Important To Get Vaccinated?

According to CDC everyone should get the MMR vaccine. It protects you from measles, mumps, and rubella. Getting vaccinated helps stop these diseases from spreading. There are two safe MMR vaccines available. They work the same way, so it doesn't matter which one you get. Kids can also get a shot that protects against chickenpox too, but this is only for children.

Who Should Get Vaccinated?

Kids Need Two Shots

All children should get two MMR shots. The first shot should be given when they are between 12 and 15 months old. The second shot should be given when they are between 4 and 6 years old. If needed, the second shot can be given earlier, but it must be at least 28 days after the first shot.

College Students Need to Be Protected

Students going to college or other schools after high school, need two shots if they are not already immune. The shots must be at least 28 days apart.

Adults Need at Least One Shot

Most adults need at least one MMR shot. Some adults need two shots, especially those who work in healthcare, travel a lot, or go to college. These people should get two shots, with 28 days between them.

Travelers Need to Be Extra Careful

Anyone traveling to other countries should make sure they are protected. Babies 6 to 11 months old should get one shot before traveling. Kids 12 months and older, teens, and adults need two shots, with 28 days between them.

Healthcare Workers Must Be Immune

People who work in healthcare should have proof that they are immune to measles, mumps, and rubella. If they are not immune, they need two MMR shots, spaced 28 days apart.

Women Thinking About Having Babies

Women who might get pregnant should talk to their doctor about the MMR vaccine. It's safe to get the shot while breastfeeding.

India’s RT-PCR testing system is capable of detecting the Bundibugyo strain of the Ebola virus, and the chances of missing a confirmed infection are very low when standardized protocols are followed, said health experts after the suspected Ebola case in Bengaluru involving a Ugandan woman tested negative.

The woman, who arrived in Bengaluru from Kampala, Uganda, on May 23, was suspected of Ebola infection after developing mild symptoms including body ache. She was shifted from a hotel to the state-run Epidemic Diseases Hospital on May 26, and her samples were sent to the National Institute of Virology (NIV), Pune. The tests today returned negative. India currently has no reported case of Ebola, the Health Ministry said.

Let’s take a look at how testing for Ebola takes place in India’s virology labs.

Speaking to HealthandMe, Dr. NK Ganguly, former Director General of ICMR, said that RT-PCR remains the confirmatory test for Ebola infection, while rapid diagnostic tests (RDTs) are mainly used for initial screening with limited sensitivity — of around 85-89 per cent.

According to him, the World Health Organization recommends that RT-PCR should only be carried out in specialized reference laboratories due to biosafety requirements. India currently has two designated Ebola reference laboratories — the National Institute of Virology (NIV), Pune, and the National Centre for Disease Control (NCDC).

"The Altona RT-PCR kit is the real star and is highly standardized. It rarely misses Ebola cases when proper protocols are followed,” Dr Ganguly said.

Can India Detect The Bundibugyo Strain?

Bundibugyo is one of the strains of the Ebola virus currently linked to outbreaks in parts of Africa, including Uganda and the Democratic Republic of the Congo (DRC). The rare strain has caused over 900 cases and more than 200 deaths.

Dr. Ganguly said the incubation period for the Bundibugyo strain can range from six to seven days up to 15 days or even three weeks.

“If a person tests RT-PCR negative during this period, the chances of being infectious are lower. However, isolation is still necessary because there may be a short window period during which the infection may not be detected,” he said.

The expert added that travelers arriving from outbreak-hit countries should remain under quarantine even if their initial Ebola test is negative.

Why Ebola Testing Is Complicated

Dr. Ganguly explained that Ebola belongs to the filovirus family, which includes several strains such as Bundibugyo, Sudan, Taï Forest and Zaire viruses.

He noted that Ebola has a high fatality rate, with nearly 50 per cent of infected individuals dying from the disease. He added that the virus can spread through several body fluids including tears, saliva, milk and urine.

In the early stages, Ebola symptoms can resemble flu, malaria or other viral illnesses, including fever, cough, sore throat, headache, diarrhea, skin rashes and body ache, making early diagnosis difficult.

Dr. Ishwar Gilada, a Mumbai-based infectious disease expert, told HealthandMe that the Bengaluru patient’s symptoms were similar to common viral infections, which is why epidemiological history and travel exposure become critical in suspecting Ebola infection.

“The symptoms of Ebola can be a little confusing because they are just like any other flu,” Dr. Gilada said, adding that travelers arriving from Ebola-affected countries should remain under observation for up to 21 days.

Are There Any Limitations In India’s Ebola PCR Testing?

Dr. Jatin Ahuja, Consultant, Infectious Diseases, Indraprastha Apollo Hospital, Delhi, told HealthandMe, there are no major loopholes in India’s Ebola PCR testing system, but there are certain limitations common to all diagnostic tests.

"One key limitation is the timing of testing. If RT-PCR is performed very early in the infection, there is a possibility of a false-negative result because the viral RNA levels may still be too low for detection," he said.

Dr. Ahuja also pointed out that test accuracy depends on whether the PCR targets are correctly aligned with the specific Ebola strain being tested. Improper alignment may reduce sensitivity.

He added that pre-analytical factors such as sample collection, storage, transport and RNA extraction also influence the final test outcome.

“Negative Ebola PCR substantially reduces concern, but interpretation always depends upon the clinical picture, travel history and exposure risk,” Dr. Ahuja said.

Hypertension is the “number one killer” in India, with nearly 1.6 million people dying from the condition every year, said Dr. Ambuj Roy, Professor of Cardiology at the All India Institute of Medical Sciences, New Delhi, today.

Speaking to media persons on hypertension, Dr. Roy said the deaths “linked to high blood pressure are five times higher than tuberculosis fatalities and exceed the combined toll of communicable diseases such as TB, malaria, dengue, and HIV”.

Calling hypertension a “silent but deadly disease,” he said most people remain unaware they have high blood pressure because symptoms are often absent.

“Ninety per cent of the time, hypertension does not cause symptoms. The only way to detect it is through regular screening,” he said.

Dr. Roy also cited the ICMR and NFHS-5 data showing that nearly 30 crore Indians are living with hypertension.

According to him, one in four adults in rural India and one in three adults in urban areas have the condition. However, “only one in three people know they are hypertensive, one in five receive treatment, and just one in twelve achieve proper blood pressure control below 140/90 mmHg”.

Lifestyle Changes Surging Hypertension Risk

Dr Roy said lifestyle changes are driving the growing burden of hypertension in India. Poor diet, obesity, physical inactivity, air pollution, stress, and poor sleep habits are major contributors, particularly among younger people.

He highlighted excessive salt intake as a key concern. While the recommended salt intake is less than 5 grams per day, average consumption in India is around 12 grams daily. He also stressed the importance of potassium-rich foods such as fruits and vegetables, noting that most Indians fail to consume the recommended 400 grams of fruits and vegetables per day.

Pollution: An Emerging Concern

Further, the Cardiologist linked pollution exposure to rising hypertension rates. Referring to studies conducted by AIIMS in collaboration with IIT Delhi, Dr. Roy said areas exposed to crop burning showed a 15 per cent higher prevalence of hypertension.

Another study found that every 10 microgram increase in PM2.5 levels was associated with a 5 per cent higher risk of hypertension.

How To Reduce Hypertension

Dr. Roy said reducing blood pressure by just 10 mmHg can significantly lower the risk of

• cardiovascular mortality by 20 per cent,
• stroke 28 per cent,
• heart failure by 28 per cent,
• coronary artery disease by 17 per cent,
• mortality by 13 per cent.

He also referred to the “TOPSPIN trial,” a large Indian hypertension study, which found that a single-pill combination therapy using two medicines reduced blood pressure by 30–40 mmHg and helped nearly 70 per cent of patients achieve blood pressure control.

The expert stated that around 70 per cent of patients may require long-term treatment or may need it lifelong. However, for nearly 30 per cent of people, hypertension can be reduced by stopping medication through:

• sustained lifestyle changes
• weight loss,
• low-sodium diets,
• exercise,
• better sleep.

‘Do Not Stop BP Medicines Abruptly’

Importantly, Dr Roy cautioned people against stopping blood pressure medicines abruptly once readings improve.

“Blood pressure is controlled because of the medicine. If you stop it suddenly, BP can rise sharply and may trigger a brain stroke or hemorrhage,” he said.

Dr. Roy also dismissed fears around side effects of antihypertensive medicines, calling them among the safest long-term drugs available. “The only side effect they have is benefits,” he remarked, adding that these medicines reduce the risk of heart attack, stroke, and kidney failure.

To reduce blood pressure naturally, the expert advised people to

• remain physically active for at least 150 minutes per week,
• reduce processed and salty foods,
• maintain hydration during heatwaves,
• adopt DASH-style diets rich in fruits and vegetables.

The American Cancer Society (ACS) has updated its colorectal cancer testing guidelines, which bring new screening options for colorectal cancer. This will give the Americans two new options of stool-based tests and blood-based screening tests.

The ACS recommended colorectal cancer screening for citizens as the risk of the disease starts at the age of 45 and continues through age 75 for those with a life expectancy of 10 more years. Thus, to make colorectal cancer tests more accessible to the masses, the new guideline gives nod to blood-based screening tests and FDA-approved new stool sample kits.

Blood-based screening tests must be done in a doctor's office, while one can use stool sample kits for testing at home. Notably, colonoscopy is still the most accurate option for detecting colorectal cancer.

The new guidelines acknowledged the fact that people are likely to choose the most effective colorectal cancer screening test. But still about 20 million eligible Americans remained untested, according to the ACS.

ACS mentions that 1 in 5 colorectal cancer cases is seen in young adults; the new guidelines were a direct result of this huge problem. Though the one who will choose colonoscopy would only have to go through screening every 10 years, on the other hand, the gap between screenings will be every one, three, or five years, depending on the specific method of testing selected.

Early Symptoms Of Colorectal Cancer

Some of the most commonly missed early signs include:

• Persistent changes in bowel habits, especially if they last more than a few days, must be taken seriously. Narrow or ribbon-shaped stools may indicate a tumor partially blocking the colon.
• Blood in the stool is one of the most common and concerning signs. While it might be due to hemorrhoids or fissures, it’s important not to assume. A proper evaluation is critical.
• Unexplained weight loss: Especially when unintentional.
• Abdominal cramps or bloating: Misinterpreted as common digestive issues.

Ignoring such a red flag delays diagnosis and drastically reduces treatment success rates. A timely visit to a healthcare provider can change outcomes.

How To Prevent Colorectal Cancer?

• Diet: More fibre-rich fruits, vegetables, and whole grains; less processed food and red meat.
• Physical activity: “Even 30 minutes of daily walking helps.”
• Screenings: Especially vital for those over 45 or with a family history.
