Do you know who can donate blood to you or who can you donate blood to? Blood donation may not be complex, but it does need to be compatible with yours and vice-versa. The blood types are determined by the presence or absence of certain antigens - substance that can trigger immune response if they are foreign to the body.
There are four major blood groups which are determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. There is also a protein called the Rh factor, which can either be present (+) or absent (-), which creates A+, A-, B+, B-, O+. O-, AB+, AB- blood types.
Group A blood type has only A antigens on red blood cells and B antibody in the plasma. B has only B antigen on red cells and A antibody in the plasma. AB has both A and antigens on red cells, but neither A nor B antibody is present in the plasma. O has neither A nor B antigens on red cells, but both A and B antibody are present in the plasma.
Your blood type determines who can you donate to. This is because there are very specific ways in which blood types must be matched for safe transfusion. The right blood transfusion could actually save you, while the wrong one could be lethal. Also, Rh-negative blood is given to Rh-negative patients and Rh-positive or Rh-negative blood can only be given to Rh-positive patients.
If you are O blood type, you can donate to O, A, B, and AB, if you are A blood type, you can donate to A and AB, if you are B blood type, you can donate to B and AB, however if you are AB, you can only donate to AB.
If you are O blood type, you can only receive from O. If you are A, you can receive from type A and O. If you are blood type B, you can receive from type B and O. If you are AB, you are lucky, you can receive blood from O, A, B, and AB.
There are more than 600 other known antigens, the presence or absence of which creates "rare blood types". Certain types are unique to specific ethnic or racial groups, this is why an African-American blood donation can be the best hope for the needs of patients with sickle cell disease, as per the Red Cross Organization.
Type O is one in high demand, as it can donate blood to anyone. O negative blood type is the universal blood type, which can donate to everyone, especially during the emergency transfusions and for immune deficient infants.
In the US, 37% Caucasian, 47% African-American, 39% Asians, and 53% Latino-American are O-positive. However, only 8% of Caucasian, 4% of African-American, 1% Asian, and 4% Latino=Americans are O-negative.
A+: 33% Caucasian, 34% African-American, 27% Asian, 29% Latino-American
A-: 7% Caucasian, 2% African-American, .5% Asian, 2% Latino-American
B+: 9% Caucasian, 18% African-American, 25% Asian, 9% Latino-American
B-: 2% Caucasian, 2% African-American, .4% Asian, 1% Latino-American
AB+:3% Caucasian, 4% African-American, 7% Asian, 2% Latino-American
AB-: 1% Caucasian, .3% African-American, .1% Asian, .2% Latino-American

Doctors are reporting a change in the way the flu is presenting as a new strain spreads across the UK. Hospital admissions linked to the flu rose sharply at the beginning of the year, with an average of 2,924 people a day admitted by January 4. Four hospital trusts have declared critical incidents, citing ongoing and intense pressure on services. These include three trusts in Surrey and one in Kent.
Surrey Heartlands Trust said winter pressures had been made worse by a rise in flu and norovirus cases. NHS national medical director Professor Meghana Pandit said the situation remains difficult, with hospitals seeing another increase in patients admitted with flu and other respiratory infections last week.
She said it is still vital for people to seek medical help when needed and reminded the public that there are many chances to get vaccinated against flu. Health Secretary Wes Streeting also stressed that flu can be dangerous, especially for older adults, young children, and those with existing health problems. He urged everyone who qualifies to get their flu vaccine as soon as possible, calling it the best form of protection.
Doctors say this latest flu strain appears to be causing different symptoms. The virus, known as subclade K, is a variant of the A H3N2 type of influenza.
Dr Mark Loafman told NBC Chicago that many patients are experiencing much higher fevers than usual. He said the fever can last five to seven days, which is longer than people typically expect and is a cause for concern.
In some cases, doctors say the fever does not respond well to common medicines such as paracetamol or ibuprofen. Lung specialist Dr Juanita Mora said this strain is linked to very high temperatures, a severe and persistent cough with heavy phlegm, vomiting, diarrhoea, and widespread joint and muscle pain.
Doctors have also noticed a rise in stomach-related symptoms, including nausea and vomiting, often referred to as gastrointestinal or GI issues. Dr Loafman said that, based on what doctors are seeing, adults infected with the subclade K strain seem to be showing more signs of GI illness than usual.
According to the NHS, flu symptoms usually appear suddenly and tend to be much more severe than those of a common cold. While most people start to recover within about a week, the illness can feel particularly harsh while it lasts.
The main symptoms usually begin abruptly and include:
Most people can deal with flu symptoms at home without needing to see a doctor. The NHS advises the following self-care measures:

People across the UK are being urged to follow basic safety steps as concerns grow over so-called “evolving” bacteria. A few decades ago, antibiotics were routinely prescribed for a wide range of illnesses and minor infections.
Today, many GPs are far more cautious about giving them out, largely because of the steady rise in bacteria that no longer respond to treatment. Figures from the UK Health Security Agency show that close to 400 antibiotic-resistant infections are being recorded every week in England.
According to the World Health Organisation (WHO), antibiotic-resistant infections develop when bacteria change over time and stop responding to the medicines meant to kill them. As a result, infections that were once easy to treat become much harder, and in some cases impossible, to cure. This can lead to serious illness, longer hospital stays, and a higher risk of death.
While antibiotic resistance can occur naturally, the WHO warns that misuse and overuse of antibiotics in both humans and animals greatly speeds up the process. This allows resistant bacteria, often referred to as “superbugs,” to survive, multiply, and spread more easily.
The biggest risk linked to these “superbugs” is that they are much harder to treat because standard antibiotics no longer work against them. Infections caused by resistant bacteria can lead to serious complications, including pneumonia and bloodstream infections, which can be life-threatening if not controlled quickly.
In a post shared on X, the UKHSA said: “Bacteria are evolving against antibiotics, with nearly 400 new resistant infections appearing each week in England.” NHS guidance has also warned that several bacteria have already developed resistance as a result of antibiotic overuse. These include MRSA, Clostridium difficile, and the bacteria linked to multidrug-resistant tuberculosis.
A major concern is that this growing trend could eventually lead to new strains of bacteria that cannot be treated with any existing antibiotics.
According to UKHSA advice, people can play a role in slowing the spread of resistant bacteria by following a few simple precautions in daily life. These include:

Many people rely on over-the-counter medicines, but a pharmacist has recently cautioned against the frequent use of some well-known remedies. Occasional indigestion or heartburn is common, but if these symptoms keep returning, there are important health points to be aware of to avoid creating bigger problems.
A pharmacist who goes by Pharmacist Anum on TikTok has shared a warning for people who regularly turn to these treatments. She explained that using certain medications too often can lead to complications, and said it is crucial for people to understand the risks before depending on them long term.
This is not the first time she has offered such guidance. Only a few weeks earlier, she highlighted key concerns around taking excessive amounts of paracetamol. In her recent video, Pharmacist Anum said: “If you’re taking over-the-counter medicines without being properly checked, you could actually be doing more harm than good. The first group of medicines I’m talking about are those used for indigestion.
“Think about products like Gaviscon, Rennies, and esomeprazole. These are easy to buy over the counter in the UK and, for most people, they are safe when used for a short time.
“Problems arise when people start depending on them, taking them several times a week or even more often. If that sounds familiar, I would urge you to speak to your GP so they can look into what’s really causing your symptoms. Using these medicines too much can raise the risk of side effects and may also hide symptoms of a more serious issue.” In the same video, she also spoke about the risks linked to overusing common painkillers. She added that there are specific things people should understand about indigestion treatments.
Taking indigestion medicines too often, including antacids and proton pump inhibitors (PPIs), can conceal serious health problems and may lead to notable side effects. These can include kidney-related issues, such as stones or damage, as well as electrolyte imbalances, including low sodium or potassium levels.
Using the recommended dose for a short period is generally safe, but long-term use can interfere with normal digestion and may even lead to dependency. This is why it is important to seek medical advice if symptoms continue, so the underlying cause can be identified.
If you have been using these medications for an extended period, or even for years, it is important to speak with your doctor. A discussion about the risks and benefits can help determine whether there may be another health issue behind your symptoms.
According to the NHS website: “Always follow the instructions provided with Gaviscon or the guidance given by your doctor. The dose you need depends on the type of Gaviscon you are using.
“If you experience occasional mild heartburn or indigestion, take Gaviscon only when needed. If heartburn or indigestion is frequent, Gaviscon can be taken up to four times a day.
“The most effective times to take it are after meals and before bedtime, whether or not symptoms are present, as discomfort often worsens during these periods.
“If you have been taking Gaviscon for more than seven days and still feel uncomfortable or in pain, speak to your doctor. If you have used Gaviscon regularly over a long time, consult your doctor before stopping, as stopping suddenly may cause symptoms to return.” Further details are available on the NHS website.
